RUBBER	:	Used as dusting powders to prevent sticking of unvulanised rubber sheet. As an additive in rubber compounds to improve flow and dispersion of vulcanising agent throught the compound.
PLASTICS	:	Internal lubricants and mould release agents for Polystyrene, Phenolics, Polyolefins, Nylon, Melamine Master Batches and Urea
POLYESTER (SMC/DMC)	:	Lubricant and mould release
ABBRASIVES	:	As a component in the coating of abrasive papers and sanding sealers.
COATINGS	:	As a flatting agent in certain Paints,Varnishes and Lacquers
PRINTING INKS	:	Acts as dulling agent
PVC Compounds	:	ZINC STEARATE is a mild Stabilizer and cannot be used alone, mixtures with other Stabilizers particularly Alkaline Earth Metal Stearates with Epoxy Stabilizers is quit effective. This is non toxic and non sulphur stainings. Hence blends with CALCIUM STEARATE are specially usefull in non toxic FDA approved compounds.
