inorganic filler modifiers / caco3,talc,silica pow

Aluminate coupling agent F-2Product InstructionProduct Instruction These products are nontoxic, odorless, color white, big adaptation temperature(80 to 280 ),stable quality, wide area application, less dosage and used convenience. Through them dealing with various fillers which are not only change surface characteristics and broken particles secondary structure, but also increased filler content and improve processing performance, and products improve yield and quality. Therefore users can lower production costs and get direct economic benefits. Chemical component Aluminium ester and a small amount of lubricant. Quality standard Appearance: white or translucent waxy solid Melting point:55 75°C Lower viscosity:≥97% Activation degrees: ≥98% Volatile component:≤1% Impurity:≤1 Thermal decomposition temperature: 220-270°C By SGS test: No toxic substances Application l Varieties of PVC filler surface modification. l PE,PM and PP masterbatch. l Rubber and varieties plastic filler suface modification. l Plastic-rubber blends materials l Varieties organic and inorganic fillers, pigments surface modification. Usage and dosage u Pretreatment method: Coupling agent of measurement is in batches or groups into the high-speed mixer, after filler’s dry for removing moisture, preheating temperature to 110 -130 degrees. Then high speed mix them about 5min, then rapid cooling.u Direct method: Coupling agent which can put into high-speed mixer directly, if filler’s water content is less than 0.5%. Filler, coupling agent and small amount of plasticizer be injected by sequence, and then inject other component, mixing in accordance with original technology.u Other usage: According to the actual situation, users can inject solvent and other additives are used.Model,application characteristics,scope,reference dosage Model Application characeristics Use scope Reference dosage F-2Wide use,good dispersion Superfine inorganic power, superfine heavy calcium carbonate, etc. 0.8-2.0% l Our factory production aluminate coupling agent can be generic, however, each targeted. l The dosage of coupling agent is not only depend on models and manufactured materials, but also important of filler surface characteristics. For example, surface polarity, specific surface area and moisture content. l Generally speaking, products which are high strength, large specific surface area, strong surface polarity and high moisture content can be into more coupling agent. For example, black aluminum hydroxide is into them 2-3%;Fillers used in injection molding or extrusion of hard and soft products can be into them 0.8-1.2%. l Use our aluminate coupling agent when not to exceed 1.3%,if users used in plastic filler products.(without stearic acid) l Filler masterbatch for PE in the use of our aluminate coupling agent 1% without using steatic acid.
