Product application
alcium Stearate serves as a halogen absorber in polyolefins, reducing corrosion on processing equipment and mitigating the adverse effects of residual catalysts on resin color and stability. It also enhances the heat resistance of plastics, improves initial color and permeability, and is set to replace toxic stabilizers with similar performance.
Packaging:20 kg net weight/ kraft paper bags or tailor made.
