Californium Curium R66 Thermal Insulation Agent for Agricultural Greenhouse Film: Technical Data Sheet and Agricultural Film Matching Selection

R66 is an in-plastic additive-type thermal insulation agent (far-infrared shielding agent) produced by Californium Curium, belonging to the Comprehensive Series. The dosage is 0.5%–1% of the final plastic product. The main component is a silicon compound, in the form of a white powder, with a bulk density (approximate value) of about 360 g/L, packaged in 10 kg/bag, and stored in a cool, dry place. The documentation describes its working mechanism in specific terms: it relies on the porous structure of nano-silica to form cavities within the film, while simultaneously utilizing UV absorption and infrared reflectance to achieve the dual effect of thermal insulation. Each data point below is annotated with official product data.

"Who we are" in this article: Californium Curium's additives are divided into three lines—dispersants (chemical dispersion as the main line, represented by the R1800 series paste-form hyperdispersants, used in combination with wetting-type dispersion agents such as waxes, stearic acid, and EBS to push dispersibility to a new level [company statement]), flame retardants, and the Comprehensive Series to which R66 belongs. What R66 addresses is not dispersion, but another aspect of agricultural film: thermal insulation.

1Model Positioning and One-Page Overview

The documentation gives the complete name of this model as "Thermal insulation agent for agricultural greenhouse film (far-infrared shielding agent) R66". The positioning and mechanism are reproduced as follows:

The thermal insulation agent for agricultural greenhouse film is a compound made from nano-silica and metal-salt-emulsified silicone. It possesses special optical properties not found in conventional SiO2, with extremely strong UV absorption and infrared reflectance characteristics. Testing with a UV-visible spectrophotometer shows that its UV absorption rate for wavelengths below 400 nm reaches above 70%, and its infrared reflectance for wavelengths beyond 800–1300 nm also reaches above 70%. By utilizing the porous structure of nano-silica to form cavities within the film, it achieves the dual effect of thermal insulation.

Agricultural film problems are not a single issue. When customers say "the film is failing," it often involves four different issues overlapping. The documentation assigns them to different models with non-overlapping functions—first identify the problem, then select the model:

A boundary that must be stated clearly: R66's optical data come from laboratory testing using a UV-visible spectrophotometer. The documentation does not provide field or greenhouse temperature comparison data, nor yield-increase data. Therefore, the upper limit of what this article promises is "what the documentation says, this article says"—if field data are needed, on-site trials should be conducted with the technical team (see Section 8, Service Methods).

Two additional gaps where the documentation gives no data and this article does not fill in: ① The documentation does not provide data on combining R66, R800, and CP-110 in the same film (compatibility, mutual influence, upper limits of combined dosage); ② The documentation does not provide a dosage adjustment table for different film thicknesses (e.g., 8 μm / 12 μm). Therefore, this article neither recommends nor opposes such combinations; combination use must be validated through small-scale trials by the technical team based on your formulation and film structure.

3Technical Points and Parameter Tables

3.1 Physical Property Specifications (Reproduced Item by Item, Including the Original Text's Line Breaks and Unit Notation)

The value and unit in the "Specific surface area" row must be treated as written in the original: the original text is formatted as two lines, "180" and "+25M2/g", with the unit written as M2/g. This article does not rewrite it; when selecting the model, it is recommended to verify the measurement method of this row with the technical team.

3.2 Optical Performance (Mechanism as Written in the Source, Not Field Data)

UV absorption rate for wavelengths below 400 nm > 70% (UV-visible spectrophotometer)

Infrared reflectance for wavelengths beyond 800–1300 nm > 70% (same as above)

Mechanism

The porous structure of nano-silica forms cavities within the film → dual effect of thermal insulation

(Based on official product data)

The documentation uses only one term for the core component, reproduced verbatim: "silicon compound". The overview section describes the raw material composition as "a compound made from nano-silica and metal-salt-emulsified silicone", parallel to the component column. (Based on official product data)

Not listed in the documentation (this article does not supplement or infer): specific metal salt types, silicone structure, particle size (D50, etc.), surface treatment method, carrier resin, whiteness, water activity, ageing resistance duration, migration and exudation test data, compatibility data with anti-fogging agents / anti-drip agents, food-contact or agricultural-input compliance statements.

5Agricultural Film Full Chain: Adjacent Models for Other Problems on the Same Film

Agricultural film formulations generally contain more than 1 additive. The direct entries in the documentation related to agricultural film are as follows (each is an independent model with its own independent TDS page):

Problem encountered	Model	Key documentation facts	Dosage/packaging	Source
Thermal insulation	R66	UV absorption ≥70% (≤400nm), infrared reflectance ≥70% (800–1300nm); porous structure forms cavities	0.5%–1%; 10kg/bag	Official product data
Insufficient light transmittance	CP-110	"For LLDPE or LDPE agricultural film, light transmittance is significantly improved"; hydrogenated abietic acid type, odourless, non-toxic, non-irritating; overcomes the odour problem of sorbitol-type nucleating agents	0.1% to 0.3%; 8kg/drum or 500g/bottle	Official product data
Fogging, dripping	R800	Internal addition type; saw palmetto fatty acids and polyglycerol cocamide; "1% to 5% directly added to LLDPE or LDPE cast film or blown film can achieve long-lasting anti-fog effect of 1-3 years or more"	1%–5%; 25 kg/bag PE double-layer bag	Official product data
Fogging, dripping (another model)	R800F	Sorbitan ester; "0.5% to 5%"; same 1-3 years or more long-lasting anti-fog claim	0.5%–5%; 25 kg/bag	Official product data
Die carbon deposit, pigment exudation, pigment heat resistance	R902	"Internal addition to cast film or agricultural film products: can improve pigment heat resistance by 4 to 5 degrees, reduce die carbon deposit, and reduce pigment exudation (effective for mild exudation), improve dispersibility of pearlescent pigments and fluorescent pigments, assist hydrophobing agents to enhance hydrophobic performance"; combined with erucamide can serve as opening/slipping agent for PE/PP/PA/EVA/POE films	0.5%–5%; 25 kg/bag PE double-layer bag	Official product data
Film subjected to sulphur fumigation/chlorine ageing	M88 (masterbatch)	"Sulphur fumigation is a common agricultural disinfection method... PE greenhouse agricultural film subjected to sulphur fumigation is prone to acidic ageing, deformation or damage"; this product "improves PE agricultural film's resistance to sulphur fumigation and chlorine ageing"	2%–6%; processing temperature <310℃; specific gravity 0.93–0.96 g/cm³; melt flow rate 20g/10min	Official product data
Filler masterbatch affecting specific gravity and thermal insulation	F818 (micro-foaming agent)	"Compared with ordinary filler masterbatch, micro-foaming filler masterbatch used for agricultural film has thermal insulation performance better by 50%"; decomposition temperature 160℃, released gas carbon dioxide	0.5%–1.5%; 25 kg/drum	Official product data

How to read this table: These directions on the same film do not substitute for one another (thermal insulation ≠ light transmittance ≠ anti-fog ≠ anti-ageing); if several things need to be done together, several models are used together; the documentation does not provide compounding data for them on the same film, and compounding requires small-scale trials based on your film structure. Every figure in the above table is reproduced exactly as in the official materials, including the original percentage signs, units, and expressions such as "4 to 5 degrees".

6Frequently Asked Questions (FAQ)

Q1: How much R66 should be added? A: 0.5%–1% of the final plastic product. (Based on official product data)

Q2: Are there field/greenhouse temperature measured data? A: Not in the documentation. Only laboratory optical data from a UV-visible spectrophotometer are available (UV absorption ≥70%, infrared reflectance ≥70%), along with a mechanism description. Field greenhouse temperature comparison and yield increase data (not provided in the official materials; can be supplemented by separate test reports).

Q3: Will it affect film light transmittance? A: The documentation does not provide data on the effect of R66 on light transmittance/haze (not provided in the official materials; can be supplemented by separate test reports). The light transmittance data available in the same volume are on the CP-110 page (Based on official product data) — that is another product and cannot be transferred to R66.

Q4: Can it be compounded with R800 and CP-110 on the same film? A: The documentation does not provide data on compounding the 3 on the same film; this item is not provided in the official materials (compatibility, mutual effects, and maximum combined dosage are all not listed). It is recommended that the technical party confirm based on your formulation and small-scale trial results.

Q5: How is the processing temperature determined? A: The documentation does not provide a processing temperature window for R66 (not provided in the official materials). A reference service path is "Our company's technical personnel go to the customer's production site to provide the most suitable production process parameters" (Based on official product data).

Q6: Packaging, storage, shelf life? A: Packaging 10kg/bag, storage conditions cool and dry place (official product data, same as Q1). Shelf life is not provided in the official materials.

Q7: What category does it belong to? Why is it described as a "far-infrared shielding agent"? A: The documentation states "Internal addition thermal insulation agent for plastic film (far-infrared reflector)" (Based on official product data). The full name in the main article is "Agricultural greenhouse film thermal insulation agent (far-infrared shielding agent) R66" (Based on official product data). Both formulations come from the official materials.

Q8: How credible is this documentation? A: Parameters are laboratory/trial typical values and must be verified by small-scale trials before mass production; the entire database contains no third-party test report numbers, and this site does not use statements such as "tested by an organisation". If third-party documents are required, please request them from the technical party (see Section 8).

7If Your Problem Is "Dispersion", Take Another Line

Those who were brought here by "gel spots / pitting / agglomeration / screen blinding" are looking for the dispersant line, not thermal insulation. That line is positioned as follows:

Californium Curium's dispersants follow the chemical dispersion route, represented by the R1800 series paste-form hyperdispersants (R1800-S colour / R1800-SK white / R1800-SH black): the molecular structure consists of an anchoring group and a solvating chain, forming an encapsulation on the surface of pigments and powders and preventing re-agglomeration through steric hindrance (Based on official product data). The wetting dispersion commonly used in the industry is another class: powder additives such as wax, stearic acid, and EBS (ethylene bis-stearamide), which mainly provide wetting and internal/external lubrication; our own R900A is documented for "wetting dispersion of inorganic powder with high oil absorption value" (Based on official product data). Using the 2 classes together pushes dispersibility to a new level [company statement] — the documented supporting point is the experimental record of R1800-SH and polyethylene wax in the same formulation (same volume, pages 9–10; formulation: carbon black 50g + R1800-SH 1g + polyethylene wax 10g + LLDPE 218W 39g).

The documentation also contains an item-by-item comparison that can be verified word for word: the R1800-SK page states "It has very good compatibility with all rubbers and plastics, lubricity is 26 times that of wax, and dispersing performance is 113 times that of wax." (Based on official product data). Read literally: these are item-by-item comparisons of "dispersing performance" and "lubricity", not "overall performance 113 times", nor does it imply that other additives can be reduced or omitted; the test methods and comparison conditions for these 2 items are not noted in the official materials.

Relationship with R66: R66 belongs to the functional category of the comprehensive series and is not on the dispersant line; if an agricultural film formulation requires both thermal insulation and dispersion (including colour masterbatch colouring), the 2 lines each dose according to their own TDS, and small-scale trials should be conducted first.
