Four kinds of uses calcium stearate

1 is used as a non-toxic PVC heat stabilizers , and has excellent lubricity. Thermal stabilizing effect as barium stearate , lead stearate, tin and cadmium stearate . But cheap, low toxicity , good processing performance . And an epoxy compound with the zinc soap , a synergistic effect , can improve the thermal stability. Commonly used in food packaging films , medical equipment and other requirements nontoxic soft products . And  Acrylic processing aid the base of lead salts and lead soaps and for rigid products , can increase the speed of gelation . This product is used for polyethylene and polypropylene , can eliminate residual catalyst on the resin color and stability adverse effects. This product is also widely used as a polyolefin , polyester reinforced plastic , phenolic resin, amino resin, thermosetting plastics lubricant and release agent. The disadvantage of this product is the initial color , at above 100 ℃ heating time is longer, will become slightly red white PVC , particularly in the formulation the presence of titanium dioxide , coloring particularly serious. The large amount of goods , there is segregation fouling . (2) is used as a lubricant in the oil field operations Stuck agent. Also heat stabilizers for PVC and a variety of plastics processing lubricant , release agent . In rigid products , and the base of lead salts , lead soap can increase the gelation speed. Also used in food packaging, medical equipment and  Diethylene glycol dibenzoate other requirements nontoxic soft film and equipment. Can be made of polyethylene , polypropylene, halogen absorbent to remove the residual catalyst on the adverse effects of color and stability . As a plasticizer in rubber processing , natural rubber and synthetic rubber can soften and almost no effect on curing . Also used as a grease thickening agent, textile waterproofing agent, paint flatting agent , when manufacturing plastic LP plasticizers.
3 Calcium stearate is an excellent non-toxic heat stabilizers and lubricants , but also adhesives, coatings and waterproofing agent flatting agents in the plastic and rubber is widely used titanium dioxide  in chemical production processes . Thermal stabilizing effect as barium stearate , lead stearate, tin and cadmium stearate . But cheap, low toxicity , good processing performance . And an epoxy compound with the zinc soap , a synergistic effect , can improve the thermal stability. Commonly used in food packaging films , medical equipment and other requirements nontoxic soft products . Also widely used as a polyolefin , polyester reinforced plastic , phenolic resin, amino resin, thermosetting plastics lubricant and release agent.
4 in cosmetics for face powder . Added to the powder in the powder adhesion, lubricity , spread the powder evenly and formability is good.
