R100

R100 belongs to the coupling-type hyperdispersant category (official English category name Coupling Dispersant) and is a processing aid (not a masterbatch, not a resin or filler itself). The title on the technical data page of the handbook is "Coupling Hyperdispersant R100 for Filled Masterbatch"; the table-of-contents line and the official full name is "Coupling-type Hyperdispersant R100 for Filled Masterbatch"; the website listing title is "Coupling Hyperdispersant for Filled Masterbatch" — the two written differences — one in the wording of "filler masterbatch" and one in the "-ness / -type" suffix — are retained by layer and recorded as they stand in each layer. (Data source: product handbook / official product data)

Overview, verbatim: "This product is a high-performance coupling hyperdispersant developed specifically for plastic filled masterbatch. It integrates advanced molecular design concepts with a special synthesis process, and combines the triple functions of coupling agent, encapsulating agent and hyperdispersant. It can effectively solve problems such as poor compatibility between inorganic fillers and organic resins and uneven dispersion in filled masterbatch, and significantly improve the performance of filled masterbatch and downstream plastic products. It is produced by the emulsification reaction of siloxane, ammonium lauryl sulfate and hyperdispersant to form a polymer with special functional groups, which can react chemically with the surface of inorganic fillers to form chemical bonding, achieving surface silicone encapsulation while having good affinity with organic resins." (Data source: product handbook / official product data)

Mechanism (four key points on the page): (1) Chemical nature — the emulsification reaction generates a polymer with special functional groups, which bonds chemically with the surface of inorganic fillers, provides surface silicone encapsulation, and maintains good affinity with organic resins; (2) Superb dispersion — greatly reduces agglomeration between filler particles, improving the stability and uniformity of the filled masterbatch; (3) Excellent coupling — enhances the interfacial bonding force between inorganic fillers and organic resins and effectively transmits stress; (4) Processing and weatherability — reduces system viscosity, improves flowability, reduces processing energy consumption and lowers screw torque; it is also chemically stable, hydrolysis-resistant and antioxidant. (Data source: product handbook / official product data)

Halogen direction: this product is not on the halogen-free model list, and its own documentation contains no statement of halogen content whatsoever — the page writes no compliance wording regarding halogen direction (neither of the two compliance terms is written). This product does not involve fluorine. (Data source: product handbook / official product data)

• Superb dispersion performance — "greatly reduces agglomeration between filler particles, so that they disperse uniformly in the resin, improving the stability and uniformity of the filled masterbatch; the product surface is smoother and the mechanical properties are better".
• Excellent coupling effect — "enhances the interfacial bonding force between inorganic fillers and organic resins, effectively transmits stress, and improves the mechanical properties of the product such as tensile strength, impact strength and flexural strength".
• Improved processing performance — "reduces system viscosity, improves flowability, reduces processing energy consumption, raises production efficiency, lowers screw torque and extends equipment service life".
• Weatherability and stability — "chemically stable, hydrolysis-resistant and antioxidant, and can improve the weatherability of the product".
• Broad applicability — "suitable for all kinds of inorganic fillers, such as calcium carbonate, talc, barium sulfate and sodium sulfate, as well as common plastic resins such as polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC)".
• Supplement at the detail-page layer (stearic acid compounding) — the molecular structure of this product leans toward non-polar characteristics, and its ability to lower the oil absorption value when used alone is limited; the page recommends synergistic compounding with stearic acid (example: based on calcium carbonate powder, 3 kg of stearic acid + 2 kg of R100 per 1 tonne of calcium powder). This content appears only at the page layer; the handbook page for this model has no corresponding clause.

Composition and synthesis (verbatim from the documentation): the main components are siloxane, ammonium lauryl sulfate and hyperdispersant (listed in parallel); "it is produced by the emulsification reaction of siloxane, ammonium lauryl sulfate and hyperdispersant to form a polymer with special functional groups, which can react chemically with the surface of inorganic fillers to form chemical bonding, achieving surface silicone encapsulation while having good affinity with organic resins". The documentation does not give the structural formulas, ratios or role division of the individual components — this page does not invent them. (Data source: product handbook / official product data)

Interfacial coupling mechanism (as stated in the page's mechanism diagram): without coupling there are gaps at the interface, stress concentration and poor mechanical properties; after coupling with R100 there is chemical bond bridging and effective stress transmission — labelled as "chemical bond bonding · silicone encapsulation · effective stress transmission". This is the key step by which filled masterbatch improves the compatibility between inorganic fillers and organic resins. (Data source: official product data)

Processing-side effects: reduces system viscosity, improves flowability, reduces processing energy consumption and lowers screw torque; chemically stable, hydrolysis-resistant and antioxidant, and can improve the weatherability of the product. The documentation does not give quantitative parameters of chemical bonding (bonding density, interface thickness), particle size changes before and after dispersion, or percentage improvements in mechanical properties — this page does not invent or infer them. (Data source: product handbook / official product data)

1. Emulsification reaction to form a polymerSiloxane, ammonium lauryl sulfate and hyperdispersant undergo an emulsification reaction to form a polymer with special functional groups.
2. Chemical bonding with inorganic fillersThe polymer reacts chemically with the surface of inorganic fillers to form chemical bonds, achieving surface silicone encapsulation; agglomeration between filler particles is greatly reduced.
3. Affinity bridging with organic resinsGood affinity with organic resins — enhances the interfacial bonding force, effectively transmits stress, and improves the performance of filled masterbatch and downstream products.
4. Processing and weatherabilityReduces system viscosity and screw torque and improves flowability; chemically stable, hydrolysis-resistant and antioxidant, improving the weatherability of the product.

The five physicochemical items recorded on the product handbook technical data page and in the official product data are as follows. The values in the table are the values as recorded in the source materials; before bulk use, confirmation by testing with your own filler and resin system is recommended.

Reading notes: (1) The source materials for this grade do not state a shelf life — this page does not draft one and does not apply the warranty terms of other grades in the same series; (2) Safety data (MSDS-type) and handling-protection items are not listed in the source materials; (3) Packaging is "20 kg plastic drum packaging and 1000 kg plastic drum packaging, or other packaging specifications provided according to customer requirements" (verbatim from the handbook). (Data source: product handbook / official product data)

Dosage follows a single basis: the recommended addition level is 0.5%-3% of the mass of the inorganic filler; the specific dosage must be determined by testing according to the filler type, particle size, resin type and required product performance. The page scale is "general recommended addition level (basis: mass of inorganic filler · 0 – 3.5% scale)".

Denominator note: this grade has only one denominator basis — the mass of the inorganic filler; it cannot be converted to or from the two other denominators, "final plastic product" and "plastic raw material". The page level also notes: the molecular structure of this product is predominantly non-polar in character, so its effect in lowering oil absorption value when used alone is limited, and co-use in combination with stearic acid is recommended (page warning sentence: "Used alone, this product has a limited effect on reducing the oil absorption value of powders, and it is recommended that it must be used in combination with stearic acid"). Thickness-direction clause: none for this grade (a search across all sources found no record relating "thickness / thinner" to this grade).

To be verified: (1) Dosage tier details and upper-limit verification — the source materials give only the overall window "0.5%-3%" and "determined by testing"; (2) The stearic acid co-use reference and the "lowering oil absorption value" statement appear only at the official website page level (the handbook page for this grade has no corresponding clause) — the technical documents supplied with the goods and written confirmation from the product side shall prevail; (3) The above are all values as recorded in the source materials; for actual production, please confirm by testing with your own filler.

The official application list is filled masterbatch, CaCO3 masterbatch and talc masterbatch; the source materials give three methods of use for the filled masterbatch production stage. Item by item as follows:

Filled masterbatch / CaCO3 masterbatch / talc masterbatch

Three items in the official application list; the overview sentence "developed specifically for plastic filled masterbatches" — it solves problems such as poor compatibility and uneven dispersion between inorganic fillers and organic resins.

Direct addition method

"During the production of filled masterbatch, add R100 in proportion together with the filler (calcium carbonate, talc, barium sulfate, anhydrous sodium sulfate, etc.) directly into a high-speed mixer, stir at high speed to 100-120℃ (filler dehydration), then add the resin and additives and stir at high speed until the current rises; when the additives have melted the resin to a softened state, discharge and pelletize."

Pre-treatment method

"First stir R100 and the inorganic filler in a high-speed mixer to 100-120℃ for pre-treatment, so that the hyperdispersant evenly coats the filler surface, and then mix and process with the resin and other additives."

Direct grinding treatment method

"According to the proportion, feed R100 together with the ore directly into a vertical mill as a grinding aid and grind directly; the ground product is an activated powder (with performance far exceeding that of a grinding aid)."

Scope of application

Various inorganic fillers (calcium carbonate, talc, barium sulfate, anhydrous sodium sulfate, etc.) × common plastic resins (PE, PP, PVC, etc.); the page for this grade has no separate compatibility matrix item.

Boundary notes

This grade and the neighbouring grades in the same series are each independent (same series ≠ same use): one covers filled masterbatch production, one covers mineral powder grinding activation, and one covers powder surface coating; values and bases are not copied from or applied to one another. No corresponding relationship is stated with either the flame retardant side or the masterbatch side — nothing is inferred and no link is established.

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

R100 / R100A / R101A all belong to the hyperdispersant series but serve different purposes (same series ≠ same use); this table draws boundaries field by field — values are not copied from one another and bases are not applied across grades.

Reading note: (1) The three grades have different denominators (inorganic filler mass / ore powder type / powder weight) — there is no basis for converting between them or comparing magnitudes; (2) The three grades have different component systems (siloxane / amide compound / polyol-modified silicone emulsion), and their indicators must not be cited interchangeably; (3) The only common item is that they belong to the same hyperdispersant series (a column juxtaposition, not a product relationship). (4) The comparison columns are the original text of each grade's own material. (Data source: product handbook / official product data)
