Spectral selectivity: UV + blue light absorbed · visible light transmitted
Switch to compare: without R5503 the UV, blue and visible bands all pass through; with R5503 the 320–470nm band is absorbed and blocked by the nano film while 440–780nm visible light passes as usual — daylighting and transparency are barely affected.
Precisely absorbs UV + blue light · resists photodegradation
By absorbing 320nm–470nm UV and blue light it effectively blocks their transmission and protects the product from photodegradation.
Visible light transmitted · clear and bright
At the same time it allows 440nm–780nm visible light through, with minimal effect on visible light, keeping the product appearance clear and bright and with almost no effect on transparency or daylighting.
Non-toxic · contains essential trace elements · >1000℃
The product is non-toxic and contains elements essential to the human body; it withstands over 1000℃ and suits many demanding environments.
Why 10nm particles give high clarity · heat resistance and dispersion
A particle size far below the visible wavelength means very weak light scattering, hence high clarity — this is the physical link between the "10nm" and "clear and bright" figures.

01Product positioning
What it is. In formulations, R5503 performs 'light-band management': it blocks UV and blue light and lets visible light through. Three qualitative descriptions align: page title verbatim 'Light blocker R5503'; official category field 'Light blocker' (English category name 'Light Blocker'); official one-liner 'Blocks UV and blue light, transmits visible light, withstands 1000°C', mechanism field 'inorganic nano UV/blue-light absorption'. (Data source: product handbook / official product data)
Attribution and coordinates (two layers listed in parallel, not merged or converted). Handbook layer: within the 'Comprehensive Series' section of the product catalog it occupies a separate line; the catalog line verbatim 'R5503: light blocker for daily chemicals/food'—immediately adjacent to the R333 line (this line comes first), each with its own independent descriptor, not mixed together. Official layer: listed under the Comprehensive Series, sequence position 24 in the official website product list; application domains classified under 'Film Packaging' domain (registered terms include 'light-blocking materials') and 'Special Functions' domain (registered terms include 'UV/blue-light blocking'). (Data source: product handbook / official product data)
Names and layer-by-layer wording (same value written differently, transcribed layer by layer). Page title 'Light blocker R5503' (edited version wording 'Light blocker R5503', only one space difference); official full name 'Daily chemicals/food dedicated light blocker R5503', English name 'Light Blocker R5503', traditional Chinese name 'Daily chemicals/food dedicated light blocker R5503'. Detail page layer: navigation '· Light blocker · TDS', page header 'TECHNICAL DATA SHEET · TDS-R5503 · REV 2026-09 · CN', above-the-fold subtext 'Nano inorganic materials · Absorbs UV and blue light · High transparency', above-the-fold badge includes 'temperature resistance over 1000℃'. (Data source: product handbook / official product data)
What problem it solves. Photo-induced degradation and the transparency trade-off: UV and blue light are common causes of photodegradation and discoloration of daily chemicals, food, and their packaging materials, while deepening color or increasing opacifying powder sacrifices transparency. R5503 places the absorption window at 320nm-470nm and the transmission window at 440nm-780nm, so its application domain falls in the direction of 'transparent materials that need to block UV and blue light'. Official application labels, three items: `Daily chemicals industry`, `Food industry`, `Transparent light-blocking materials`. (Data source: product handbook / official product data)
What it is not. It is not a flame retardant (not in the flame retardant series); not an anti-gamma-ray aging agent (R333's category, for radiation aging protection); not a thermal insulation agent / far-infrared reflective agent (R66's category, for infrared reflection and insulation); not a hyperdispersant or coupling agent; not a color masterbatch, pigment, or powder filler; there is no corresponding masterbatch grade.
Data boundaries (stated up front). This grade's page has only four columns: overview, features (five items), technical specifications (six items), application fields. There is no dosage column, no packaging / storage / transportation / usage / precautions / quality commitment entries, and no compliance statement sentence or test-method column. The numerical values below are all as recorded in the source data. (Data source: product handbook / official product data)
- High-efficiency light-blocking performance: precisely absorbs UV and blue light, protecting products from photodegradation
- High transparency: minimal effect on visible light, keeping product appearance clear and bright
- Safe and environmentally friendly: the product is non-toxic; its composition contains essential elements for the human body, for more peace of mind in use
- High-temperature resistance: withstands temperatures over 1000℃, suitable for various harsh environments
- Broad applicability: food packaging, food packaging, etc., easy to process. (★ The
- item's original text reads thus—'food packaging' is repeated, as written on the data page, transcribed unchanged)
02Formulation system & mechanism of action
Identity and composition. The 'Main component' column in the technical specifications table says verbatim 'nano inorganic material'; the official field layer `main_component` also reads 'nano inorganic material', and the official table 'Appearance' value is also 'nano inorganic material'. The source does not name the specific inorganic substance (no chemical formula, CAS number, or elemental composition entry)—not inferred or supplied on its behalf. (Data source: product handbook / official product data)
Product overview sentence (verbatim). The source original: 'This light blocker is made of inorganic nano materials. By absorbing UV and blue light in the 320nm-470nm band, it effectively blocks the transmission of UV and blue light; at the same time, it allows visible light from 440nm-780nm to pass through, with very little effect on transparency and daylighting.' This sentence is the entire mechanism skeleton: inorganic nano materials + absorption (by absorbing UV and blue light in the 320nm-470nm band) + transmission (allowing visible light from 440nm-780nm to pass). (Data source: product handbook / official product data)
Mechanism reading (technical claim layer). Consider three points: the absorption band 320–470nm (UV + blue light) and the transmission band 440–780nm (visible light) each maintain their boundaries; particle size determines transparency—10 nm is far smaller than visible light wavelengths, light scattering is extremely weak, and this is the physical basis for 'high transparency' (comparison card verbatim '10 nm ≪ 400–780 nm · extremely weak scattering', '≈ 1/40–1/78 of wavelength', mechanism note 'particle size far smaller than visible light wavelength → extremely weak light scattering → high transparency'); temperature resistance determines the applicable range (over 1000℃).
Detail page layer (transcribed item by item). Spectral window title 'SPECTRAL WINDOW · R5503', section title 'Spectral selectivity: UV + blue light absorbed · visible light transmitted', two segment labels 'Absorption 320–470nm' 'Transmission 440–780nm visible light', legend 'Absorption band 320–470nm (UV + blue light)' 'Transmission band 440–780nm (visible light)'; toggle comparison 'Without R5503 · full transmission' ↔ 'With R5503 · UV + blue light blocked', readout line '320–470nm absorbed · 440–780nm visible light transmitted · daylight almost unaffected'; film layer 'R5503 nano film', segments 'UV 320–400nm' 'Blue light 400–470nm' 'Visible 440–780nm'; dispersion line 'Dispersed in water (H) · alcohol (C) · ether, etc.'; batch note 'A COA test report is included with each batch.'; marquee ten items: nano inorganic NANO-INORGANIC, absorbs UV + blue light, 10nm particle size, >98% active content, temperature resistance >1000℃, high transparency HIGH CLARITY, daily chemical packaging DAILY CHEM, food packaging FOOD PACK, water / alcohol / ether dispersion, anti-photodegradation ANTI-DEGRADATION; feature cards also include 'Broad applicability' ('compatible with various transparent material systems') and 'Nano inorganic carrier' ('dispersed in water/alcohol/ether'). (Data source: official product data)
★ Overlap region presented as is. Detail page footnote verbatim: 'Note: the absorption band 320–470nm and the transmission band 440–780nm overlap in the 440–470nm interval; this is presented as the original specification states.' Transcribed, no judgment of right or wrong, no substitution or correction. (Data source: official product data)
Effect boundaries. The source provides only band boundaries and qualitative features; quantitative values such as absorption rate / transmission rate curves, haze, and light transmittance, as well as quantified duration and rating for photodegradation protection, are not given—no calculation, no extrapolation. (Data source: product handbook / official product data)
03Key parameters
[Technical Specifications] The six items in the table, verbatim (primary basis). (Data source: product handbook / official product data)
| Item | Value / description |
|---|---|
| Main component | Nano inorganic material |
| Appearance | Nano inorganic material |
| Particle size | 10 nm |
| Active content | > 98% |
| Solvent | Water (H), alcohol (C), ether, etc. |
| UV/blue light blocking | 320-470 nm |
| Visible light transmission | 440-780 nm |
| Temperature resistance | > 1000 °C |
| Three-layer wording presented side by side (same value, different wording; not standardized or rewritten) | (Data source: product handbook / official product data) |
| Seven items of technical data at the official field layer | Appearance `nano inorganic material`, particle size `10 nm`, effective content `> 98%`, solvent `water(H), alcohol(C), ether, etc.`, UV/blue light blocking `320-470 nm`, visible light transmission `440-780 nm`, temperature resistance `> 1000 °C`. Two notes on readings: First, the source of the official-layer 'temperature resistance' item is handbook feature ④ ('temperature resistance over 1000℃'), not new data; Second, the official layer writes the two bands as two independent lines, while the handbook layer writes them in the overview sentence—same value, different position, not converted. (Data source: product handbook / official product data) |
| Detail-page layer metrics quick view (same-position wording) | Particle size / effective content row '10 nm · >98%', composition row 'nano inorganic material · non-toxic', solvent row 'water(H) · alcohol(C) · ether, etc.'. The compositional character is carried by feature ③—'The product is non-toxic, and its composition includes essential elements for the human body'; the elements are not named. (Data source: official product data) |
The values in the table are as recorded in the source materials; before bulk use, small-scale trial verification is recommended. (Data source: product handbook / official product data)
04Recommended dosage window
Conclusion first: the materials for this grade do not have a 'recommended dosage / addition amount' column. The grade page's four columns (overview / features / technical specifications / application fields) have no dosage column; the six technical specification items and all other columns contain no dosage figures ⇒ this page does not give a dosage value. (Data source: product handbook)
| Scenario | Dosage | Conditions & notes |
|---|---|---|
| Handbook layer | No dosage column (four-column structure, no addition amount / recommended dosage-type item) | No value |
| Official data layer | The dosage field records a percentage value with no denominator specified; after full-source verification, it has no handbook source (the handbook has no corresponding column, the value is not recorded anywhere in the full source, the field has not been verified against source text) | No source (isolated handling) |
| Detail page layer | No dosage entry (the metrics overview lists six spectral and physicochemical indicators: bands / particle size / effective content / temperature resistance / solvent / composition) | No value |
Three points must be made clear. First, there is no 'both are present'—neither the handbook layer nor the detail page layer has a dosage value; only the official data layer retains an isolated field value with no handbook counterpart. Second, this value is handled according to 'the material page prevails': isolated handling, not participating in any statement on this page (to be handled after confirmation from the material side; this page does not alter official website data on its behalf). Third, the external release side has been handled accordingly: the official product data provided externally does not contain a dosage field ⇒ for customers, this grade has no official dosage value that can be cited. (Data source: official product data)
The above are values recorded in the source materials; for actual production, please conduct small-scale trial confirmation in combination with your own system and process. (Data source: product handbook / official product data)
05Applications
Application fields sentence (verbatim · primary basis): 'Suitable for the daily chemicals industry, food industry, and other transparent material fields requiring UV and blue light blocking.' (Data source: product handbook / official product data)
- Application fields sentence (verbatim · primary basis)
- 'Suitable for the daily chemicals industry, food industry, and other transparent material fields requiring UV and blue light blocking.' (Data source: product handbook / official product data)
- Application wording across layers presented side by side
- (Data source: product handbook / official product data)
- Application domain placement
- 'Film packaging' domain (scope term includes 'light-blocking material') + 'special functions' domain (scope term includes 'UV/blue light blocking')—the two domains are presented side by side, not converted. (Data source: official product data)
- Two boundary points
- First, do not extrapolate industries: the materials list only the above three types of occasions; the industry domain registration in the official application mapping layer is empty (the note states explicitly: the instructions' [Application Fields] only list the daily chemicals industry, food industry, and 'transparent material fields requiring UV and blue light blocking'; no other industry field wording appears) ⇒ do not write extrapolations of the form 'suitable for a certain industry.' Second, the masterbatch side has no counterpart: neither the masterbatch materials nor the official data layer has an entry for this grade, nor is there any statement of the form 'R5503 is used internally'—do not infer. (Data source: product handbook / official product data)
- Selection-oriented reading approach (technical claim)
- First determine four things: the band to block, the visible light to retain, the dispersion medium (water / alcohol / ether system), and the operating temperature; then perform sample verification and small-scale trials.
Field issues & application examples (as recorded in the source material)
| Field issue | What the source material states |
|---|---|
| What exactly is R5503? Is it the same as R333 and R66? | No. R5503 is a light-blocking agent: it absorbs UV and blue light at 320nm-470nm and allows visible light transmission at 440nm-780nm. R333 is an anti-gamma-ray aging agent, and R66 is a thermal insulation agent (far-infrared reflective agent). The three grades differ in category field and target of action, and are not interchangeable. (Data source: product handbook / official product data) |
| What is the recommended addition amount? | The materials for this grade have no dosage column (the four-column structure and the six technical specification items all have no dosage row) ⇒ this page does not give a dosage value. The dosage field in the official data layer does not correspond to this grade's material page (the value has no handbook source; it has been handled according to 'the material page prevails', isolated handling, and does not participate in any statement on this page), pending confirmation from the material side; the official product data released externally likewise does not contain a dosage field. For actual addition, please refer to the technical documents supplied with the goods and the supplier's application guidance. (Data source: product handbook / official product data) |
| What does it block and what does it let through? | It blocks UV and blue light (absorption band 320–470nm) and lets visible light through (transmission band 440–780nm). Its particle size of 10nm is far smaller than visible light wavelengths and scattering is extremely weak, so while blocking light it has very little effect on transparency and daylighting. (Data source: product handbook / official product data) |
| Why emphasize particle size and temperature resistance? | Particle size determines transparency: 10 nm is an order of magnitude different from visible light wavelengths (400–780nm) (the detail page notes '≈ 1/40–1/78 of the wavelength'), and light scattering is extremely weak—this is the physical basis for 'high transparency.' Temperature resistance determines the applicable scope: temperature resistance exceeds 1000℃ (the official field layer writes '> 1000 °C'). Both items are values recorded in the source materials. (Data source: product handbook / official product data) |
06How it differs from related grades
Overall verdict: the three grades have different identities, are not equivalent, and are not substitutes for one another. R5503 = light-band management (absorbs UV / blue light, transmits visible light); R333 = protection against material aging under gamma irradiation; R66 = infrared / thermal insulation (UV absorption + infrared reflection). Discrimination depends only on the category field and official full name. (Data source: product handbook / official product data)
| Comparison item | R5503 (this grade) | R333 | R66 |
|---|---|---|---|
| Official full name | Light blocker R5503 for daily chemical products/food | Anti-gamma-ray aging agent R333 for PP/PE | In-plastic additive thermal insulation agent R66 (far-infrared reflector) |
| Handbook page title | Light blocker R5503 | Anti-gamma-ray aging agent R333 for PP/PE | (Not cited in this table) |
| Category field | Light blocker / Light Blocker | Anti-gamma-ray aging agent | Thermal insulation agent |
| Official one-liner | Blocks UV and blue light, transmits visible light, withstands 1000°C | Resistant to 60Co irradiation, suitable for medical and aerospace applications | UV absorption 70%+, infrared reflection 70%+ |
| Main components | Nano inorganic material | Hindered amine derivative, chelating agent, phosphate ester dilaurylamine | Silicon compound |
| Dosage basis | The source does not provide a dosage column (this field has no source at the official level and is handled in isolation) | 0.5%-1.2%; 1.2%-1.8% (denominator not specified) | 0.5%—1% of the final plastic product (denominator = final plastic product) |
| Appearance | Nano inorganic material (value of 'Appearance' in the official table) | White uniform fine particles (powder) | White powder |
| Target | 320–470nm UV and blue light (transmits 440–780nm visible light) | Material aging under gamma-ray irradiation | Infrared (far-infrared reflection) + UV absorption |
Reading note: The comparison only explains each grade's source positioning and applicable targets; values for each grade cannot be applied interchangeably; discrimination is based on the official full name and category field. (Data source: product handbook / official product data)
07Usage & storage
The following points are taken item by item from the source record; items not listed in the source are not drafted.

08FAQ
What exactly is R5503? Is it the same as R333 and R66?
No. R5503 is a light blocker: it absorbs 320nm-470nm UV and blue light and allows 440nm-780nm visible light to pass. R333 is an anti-gamma-ray aging agent, and R66 is a thermal insulation agent (far-infrared reflector). The three grades have different category fields and targets, and are not substitutes for one another. (Data source: product handbook / official product data)
What is the recommended dosage?
This grade's source does not have a dosage column (the four-column structure and six technical specification items have no dosage row) ⇒ no dosage value is given on this page. The dosage field at the official data layer does not correspond to this grade's source page (this value has no handbook source and has been handled according to 'the source page prevails' and in isolation, and does not participate in any statement on this page), pending confirmation from the source side; the externally released official product data also does not contain a dosage field. For actual addition, please follow the technical documents supplied with the shipment and the supplier's application guidance. (Data source: product handbook / official product data)
What does it block, and what does it let through?
It blocks UV and blue light (absorption band 320–470nm) and lets visible light through (transmission band 440–780nm). The particle size of 10nm is much smaller than the wavelength of visible light, and scattering is extremely weak; therefore, while blocking light, it has very little effect on transparency and daylighting. (Data source: product handbook / official product data)
Why emphasize particle size and temperature resistance?
Particle size determines transparency: 10 nm differs by an order of magnitude from visible light wavelengths (400–780nm) (detail page notes '≈ 1/40–1/78 of the wavelength'), and light scattering is extremely weak——this is the physical basis for 'high transparency'. Temperature resistance determines the applicable range: temperature resistance exceeds 1000℃ (written as '> 1000 °C' at the official field level). Both items are values recorded in the source. (Data source: product handbook / official product data)
How is halogen labeled?
This grade is not on the list of nine true halogen-free grades, and the source has no halogen-related statement either ⇒ the two compliance labeling terms are both omitted and treated as 'not applicable'. (Data source: product handbook / official product data)
How are packaging, storage, and transport handled?
Not provided in the source (this grade's page has no packaging / storage / transport / usage method / precautions entries) ⇒ for the specific part number, request the technical documents supplied with the shipment from the supplier; a COA test report is included with each batch. This page does not draft packaging specifications or storage and transport conditions. (Data source: product handbook / official product data)
Can it be used in food-contact or daily chemical formulations?
The application field sentence in the source states 'daily chemical products industry, food industry, and other transparent material fields requiring UV and blue light blocking'; Feature 3 separately states 'the product is non-toxic, and its composition includes essential elements for the human body'. Food-contact compliance statements and document numbers are not provided in the source——for formal projects, request compliance documents before deciding. (Data source: product handbook / official product data)
AppendixData sources
The data on this page comes from two types of sources and can be traced item by item:
- Facts come from two types of sources: product handbooks (additive main volume / additive content edited version / comprehensive series special volume; the three volumes corroborate each other with the same text, and were additionally cross-checked against the full handbook text) and official product data (product fields, list and series data, application domain and application mapping data, detail page copy and multilingual naming, external release surfaces); data are annotated with sources inline and can be checked back item by item.
- Cross-reading with the two articles on R333 and R66: the category, full name, main components, dosage basis, and direction in the Section 6 comparison table are five points aligned with the two articles, with no conflict; the record in the R66 article that 'the source does not establish a comparison relationship between R66 and other functional directions' is aligned with §6.2 of this page.
- All values on this page are values recorded in the source; for actual production, please conduct small-scale trials for confirmation in combination with your own formulation, equipment, and raw materials.
Not covered by the source material (not written on this page — to be added later)
- The dosage field at the official data layer does not correspond to this grade's source page (this grade's page has no dosage column)——it has been handled according to 'the source page prevails' and in isolation, and does not participate in any statement on this page; pending confirmation from the source side.
- Packaging / storage / transport / usage method / precautions / quality commitment / compliance statement / test method: none are provided on this grade's page (see Section 7 for the list of omissions).
- Component details: specific inorganic substance names, chemical formulas, CAS numbers, elemental composition——not provided in the source and not drafted.
- Optical quantification: absorptivity / transmittance curves, haze, light transmittance, scattering rate——the source only provides band boundaries (not inferred).
- Measurement conditions for the temperature resistance basis: the measurement method and duration corresponding to >1000℃——not provided in the source.
- Food-contact compliance: declaration of conformity and document number——this grade's page has no compliance sentence.
- Same-family / adjacent-position relationships: the source does not establish any pairing or substitution relationship between this grade and any other grade (including R333 / R66); if there is an internal comparison basis, please supplement the record and synchronize this page.
