Vinyl modified polysiloxane Purified 100%

R-8501 is a vinylmethoxyethoxy polysiloxane, not only keeping good vinyl reactivity, but also constribute much more siloxane reactivity, could better react with filler surface so as to improve compatibility between filler and polymer. At the same time,as a flexible chain of Si-O bond, longer chain make better wettability which good help to filler dispersion.

Zinc Stearate

Zinc stearate is a "zinc soap" that is widely used industrially. In this context, soap is used in its formal sense, a metal "salt" of a fatty acid. It is a white solid that repels water. It is insoluble in polar solvents such as alcohol and ether but soluble in aromatic hydrocarbons (e.g., benzene) and chlorinated hydrocarbons when heated. It is the most powerful mold release agent among all metal soaps. It contains no electrolyte and has a hydrophobic effect. Its main application areas are the plastics and rubber industry, where it is used as a releasing agent and lubricant which can be easily incorporated.

magnesium hydroxide Purified >99.6%

Features and Main application:


a)      YR6N Magnesium hydroxide fire-retardant is high purity Mg(OH)2, ,the surface is specially treated with vinyl silane.


b)      because surface is after organic reaction,so it greatly reduces surface energy, and improves the dispersion and liquidity in organic matter accordingly,


c)      as a no halogen flame retardant,it is mainly used in PA,TPE and Polarity PE copolymer(EVA EEA etc)  and also Rubber .Low smoke density and high thermal stability. initial decomposition temperature  is about 340?.No Poisonous and causticity air when degradation.


d)      Because of aminosilane surface treatment,it is good for improving the compatibility of polymer and filler when casting mold and modification.


e)      With pretreatment of powder when chemical reaction,it will deduce clients’ input for facility and processing steps.further Lower the cost of facility and labor
