Calcium Stearate
Calcium stearate is a white, odorless powder widely used in the rubber and plastic industries as a lubricant, stabilizer, and anti-blocking agent. It effectively reduces friction, improving the processing of plastics, especially in PVC processing. As a plasticizer, it enhances the mechanical strength and heat resistance of materials, reducing friction and sticking during production, thus improving efficiency and product quality. For plastic products requiring enhanced smoothness and flowability, Calcium Stearate offers an ideal solution.
