R900A

What it is. R900A is a liquid color masterbatch base—in the words of the documentation, a 'carrier base with hyperdispersing and high-lubricity properties developed specifically for rubber and plastics liquid color masterbatch.' In liquid color masterbatch manufacturing, it acts as a base and carrier, carrying, wetting, and dispersing pigments and functional additives; it is not itself a finished color masterbatch, and the color is user-defined. Its official full name is verbatim 'Liquid Color Masterbatch Base R900A', English name 'Liquid Color Masterbatch Base R900A', official category field 'Liquid Masterbatch', and English category name 'Liquid Masterbatch'. (Data source: product handbook / official product data)

Names and wording at each level. The technical data page title for this grade is verbatim 'Liquid Color Masterbatch Dedicated Base R900A'; the product catalog line is verbatim 'R900A: liquid color masterbatch base, dedicated dispersant for degradable masterbatch, wetting and dispersion of high oil-absorption inorganic powders, black color masterbatch, etc.'; the official website product list page title is written as 'Hyperdispersant Dedicated to Liquid Color Masterbatch', the detail page main title 'Dedicated Base for Liquid Color Masterbatch', and the subtitle contains 'polyolefin ether · narrow molecular weight distribution polymer liquid · temperature resistance 80–280°C'. (Data source: product handbook / official product data)

What problem it solves. Liquid color masterbatch is a coloring solution that uses liquid as carrier; the documentation states one core value most directly: 'Liquid color masterbatch can effectively eliminate color spots and speckles on the surface of products, with very ideal results; therefore, in film extrusion and fiber drawing, its application has advantages unmatched by other coloring methods.' The remaining points are: higher pigment content per unit weight, greatly reduced addition ratio, saving coloring cost; higher coloring strength, hiding power, and product gloss; simple processing conditions, clean coloring environment, uniform and stable color; multiple functional additives can be 'loaded' into the same system to make multifunctional masterbatch. (Data source: product handbook)

Official fields and series coordinates. The official one-line positioning is verbatim 'liquid color masterbatch carrier, degradable masterbatch dispersion'; the mechanism field is 'hyperdispersing + high-lubricity carrier'; the application list is: liquid color masterbatch, degradable masterbatch, wetting of high oil-absorption inorganic powders, black masterbatch; the main component field is 'polyolefin ether'. R900A is included in the hyperdispersant series, at sequence position 13 in the official website product list (previous one R780, next one R101A). (Data source: official product data)

What it is not. It is not the masterbatch itself (masterbatch is a finished-product form from another product line; there is no 'internal use' phrasing or mapping relationship between this grade and masterbatch); it is not a resin or filler itself; nor is it a post-treatment agent for coating on the surface of products. R900, with a similar number, is another independent grade (composite dispersant, aimed at inorganic powders and filler applications); the two grades are not sub-codes or substitutes of the same product—see Section 6 for the boundary. (Data source: product handbook / official product data)

Documentation boundaries (stated first). The documentation for this grade does not provide dedicated experimental data tables or curves, nor production-line measured data; shelf life and safety data (MSDS-type) are not listed; 'temperature resistance 80-280℃' is not accompanied by test conditions or inspection method descriptions. The values below are all values recorded in the documentation, not performance commitments for finished products. (Data source: product handbook / official product data)

Composition and form. The documentation summary sentence is verbatim: 'R900A is a liquid color masterbatch base developed, produced, and sold by our company, a polymer liquid produced under high-temperature and high-pressure conditions using a precise ratio. It has excellent molecular weight and a fairly narrow molecular weight distribution, and outstanding dispersion performance. R900A is mainly suitable for plastics, rubber, and other products with temperature resistance 80-280℃, or for wetting and dispersion of high oil-absorption inorganic powders, or for black masterbatch production, etc.' The main component is verbatim 'polyolefin ether'. In form, it is a polymer liquid: colorless and transparent in the normal-temperature range, turning into a white paste in the low-temperature range (see Section 3 for phase-change dual state). (Data source: product handbook / official product data)

It is a 'carrier', not a finished color masterbatch. In the description section for varieties in the same series, the documentation states: 'R900A is a carrier base with hyperdispersing and high-lubricity properties developed specifically for rubber and plastics liquid color masterbatch.' The official mechanism field is consistent with this—'hyperdispersing + high-lubricity carrier'. These two layers of wording define its role as a carrier: on one end, it relies on hyperdispersing ability to wet and stabilize difficult-to-disperse objects such as high oil-absorption inorganic powders; on the other end, it relies on high-lubricity properties to let the system flow smoothly during production and processing. (Data source: product handbook / official product data)

Why use liquid color masterbatch (documentation copied item by item). The documentation has two additional sentences directly stating end-user benefits: First, 'Products made with R900A liquid color masterbatch base are almost suitable for addition to any plastic or rubber.' Second, 'With liquid color masterbatch, processing conditions are simple, operation and use are convenient, the coloring environment is clean, color is uniform and stable, the finished-product qualification rate is high, economic benefits...... Therefore, the liquid color masterbatch coloring solution will have broader application space in the future.' (Data source: product handbook)

Compatibility and processability. The documentation states that the selected organic liquid is 'fully compatible with plastic raw materials' and 'in practical applications instead improves certain processing techniques of plastics (e.g., lowering processing temperature, increasing flowability), and enhances certain physical properties of plastic raw materials'; the same paragraph also gives a list of functional modules (anti-blocking and slip agent, antistatic agent, clarifying agent, weather-resistance agent, antioxidant, mold-release agent, foaming agent, etc.), which can be added in appropriate amounts according to customer requirements to make multifunctional masterbatch products. (Data source: product handbook / official product data)

Parts not provided by the documentation. Molecular-level descriptions of the dispersion mechanism (anchoring groups, solvated chain structures), quantitative data on particle size and dispersion degree, viscosity-temperature curves, etc., are not provided for this grade; this page does not draft them on its behalf. (Data source: product handbook)

The physicochemical properties given on this grade's technical data page are as follows (recorded verbatim):

Reading notes (three items). 1. The phase-change dual states are two temperature phase states of the same product, not two products: white paste below 0°C and colorless transparent liquid above 5°C; the detail page presents this pair of states as "temperature phase-change switching". 2. Same value, different wording, recorded as written: the detail page writes appearance as "white paste below 0°C, colorless transparent liquid above 5°C", pH as "6.0 – 7.0", viscosity as "200 – 600 mPa·s", and density as "1.220 g/cm³"; the values are consistent, the wording is layered, and this page records them by layer without unifying them on its own. 3. Concepts and boundaries: density 1.220g/cm³ is an ex-factory typical value basis, and "temperature resistance 80-280℃" is the applicable temperature range given in the materials; the two are not the same concept; this grade has no solids content item, so do not apply the solids content value of a neighboring grade; the table above is for grade selection comparison and incoming material verification, and before production, the technical documents supplied with the goods and small-scale trial results shall prevail.

Four dosage bases coexist for R900A in the materials and official data, and their denominators differ. To avoid errors from converting among them, all are listed by denominator layer here, without choosing only one.

Basis 4 · Official website detail page three-interval scale (same values, layered wording). The official website detail page uses "addition level interval (based on final plastic product / article mass)" as the scale title and lists three intervals separately: transparent articles "0.2% – 0.5%", solid-color articles "0.6% – 2.0%", and base material in the final plastic product "1% – 10%"; the scale note is verbatim: "0–10% shared scale: the three intervals for transparent articles / solid-color articles / total base material are not to be confused with each other." (Data source: official product data)

Basis 3 · Official data layer dosage field (denominator = liquid masterbatch formulation). The dosage field registered in the official product data entry is verbatim: "15-40% (relative to liquid masterbatch formulation)" — the denominator is the liquid masterbatch formulation (i.e., the proportion of base material in that formulation); the source has only this one sentence. This page records it verbatim, does not supplement it, and does not judge right or wrong; the correspondence between it and the various handbook bases is not stated in the materials (for registration, see "Items to be verified" item 1 at the end). (Data source: official product data)

Three main scenarios. The official application list item by item is: liquid masterbatch, degradable masterbatch, wetting of high oil absorption inorganic powder, black masterbatch; the technical data page [Application Areas] entry is verbatim: "For production of various liquid masterbatches, medical-grade and cosmetic-grade products, pharmaceutical excipients, softening agents for chemical fibers, rubber and plastic products, etc. Or for wetting and dispersing high oil absorption inorganic powder, or for production of black masterbatches, etc." The detail page lists the tracks in five cells: production of various liquid masterbatches; medical-grade and cosmetic-grade products and pharmaceutical excipients; softening agents for chemical fibers and rubber/plastic products; wetting and dispersing of high oil absorption inorganic powder; production of black masterbatches. (Data source: product handbook / official product data)

Covered systems and temperature range

The materials overview sentence states: "mainly suitable for use in plastics, rubber, and other products with temperature resistance of 80-280℃"; official application domain data lists R900A in both the "masterbatch pigment" domain and the "rubber elastomer" domain. The compatibility statement is "fully compatible with plastic raw materials"; for specific grades, a small-scale trial is recommended first. (Data source: product handbook / official product data)

Changes perceivable by end users

Color spots and speckles on article surfaces are effectively eliminated; in film extrusion and fiber spinning, the materials state it has advantages unmatched by other coloring methods; higher coloring strength, hiding power, and gloss, with the addition ratio greatly reduced. (Data source: product handbook / official product data)

Boundaries (two items)

1. No correspondence with the masterbatch line: between this grade and the masterbatch volumes, there is no "internal use" phrasing, nor any mapping relationship between masterbatch and additives; do not calculate according to a correspondence relationship. 2. It is not the same product as R900: R900 is another independent grade, with different application direction and dosage basis (see Section 6); values for the two grades must not be transferred between them. (Data source: product handbook / official product data)

Field issues & application examples (as recorded in the source material)

At positions with similar codes, the data also includes an R900 item. The two grades are two independent products: each has its own independent name, technical data page, and application positioning; the data does not describe the two as parent/sub-codes, upgrades, or substitutes, so the compositional wording, physicochemical values, and application directions of the two grades must be read item by item separately; values must not be copied from one another, and specifications must not be interchanged. Special note: R900A is an independent grade, not a suffix sub-code of R900. (Data source: product handbook / official product data)

Reading note: The comparison only explains each product's data positioning and applicable objects; values for each grade must not be interchanged. Identification should be based on the official full name and category field. (Data source: product handbook / official product data)

The following points come item by item from the data records; items not listed in the data are not supplied by inference.

The data on this page come from two types of sources and can be traced item by item:

• The facts on this page come from two traceable sources: the product handbook (technical data page, catalog rows, advantages clauses) and official product data (product entry fields, site dictionary, product list, application domain, and detail page copy).
• Dosage, specifications, and packaging are transcribed verbatim from the original text; where the same value is written differently, it is retained by layer without unified rewriting; original wording in quotations (such as 'shi yong yu') is transcribed unchanged.
• This page strictly separates R900, whose code is similar: R900 values are used only in Section 6 for boundary comparison, with the source grade named at each point; R900A dosage, specifications, and applications are taken exclusively from this grade's own data.

Not covered by the source material (not written on this page — to be added later)

• The dosage field in the official data layer '15-40% (relative to the liquid masterbatch formulation)' and the handbook [Addition Content] (1%—10% of the final plastic product) coexist with different denominators; the corresponding relationship is not explained in the data—this page registers them side by side and does not convert them into one another; it is recommended to align with the official basis before publication.
• In the official website copy layer, the wording 'polyolefin ether + ester functional groups' is also seen, which is inconsistent with 'polyolefin ether' on this grade's technical data page and in the official field—this page uses 'polyolefin ether', and that added wording is not adopted and has been recorded.
• Inter-layer writing differences: '0°C and below…' and '0°C and below…', '6.0-7.0' and '6.0 – 7.0', '200-600mPas' and '200 – 600 mPa·s' coexist—transcribed by layer and not changed into one another.
• Shelf life and safety data (MSDS type) are not listed; 'temperature resistance 80-280℃' has no test-condition description; there are no dedicated experimental data tables or curves.
• There is no thickness-dosage direction clause available for verification; the company profile list sentence also has the wording 'Liquid masterbatch base (dedicated dispersant for degradable masterbatch)' (coexisting with catalog rows, etc.)—the main text follows the official full name, and the list-sentence wording is not adopted.
