Zinc stearates

Zinc stearates are insoluble in polar solvents, but more soluble in aromatic compounds and chlorinated hydrocarbons when heated. Their main application areas are the plastics and rubber industries where they are used as release agents and lubricants which can be easily incorporated. The outstanding clarity and heat stability properties of our crystal clear zinc stearate grades make them particularly suitable for impact and crystal grade polystyrene and other clear polymers. Zinc stearate functions as an acid scavenger and processing aid in certain polyolefin applications.
