Sodium Stearate
Sodium stearate is a common organic sodium salt widely applied in rubber and plastic processing. It acts as a surfactant, emulsifier, and stabilizer, improving the flowability of plastics and enhancing their processing performance. In rubber production, it reduces mold adhesion and enhances the surface quality of products while improving the heat and weather resistance of plastics.
