FunctionZinc stearate has good thermal stability, low initial coloration, good light stability, and has a synergistic effect with calcium stearate and barium stearate. It has a foam stabilizing effect and can be used as a foaming aid for foaming products. Used as a lubricant for cosmetic powder, glue, and plastic products, zinc stearate is used as a stabilizer for polyvinyl chloride. With barium-cadmium soap, it is mainly used for soft products. It is characterized by inhibiting the initial coloration of Chemicalbook and avoiding vulcanization pollution. Zinc stearate can also be used as styrene series (polystyrene and ABC, SAN resin), phenolic resin, amino resin and other thermosetting plastics and polyester plasticizers, lubricants and release agents for transparent products. In the rubber industry, it is used as a lubricant and anti-sticking agent for rubber compounds, and an activator for vulcanization catalysts. Polishing agent for textile products, paint industry, enamel industry, flattening agent.
