The core functions of PE wax in PVC: Excellent lubrication: As a highly effective external lubricant, it provides PVC with excellent metal release properties, preventing adhesion during extrusion, calendering, and injection molding. Improved surface and appearance: Significantly improves the surface gloss and smoothness of PVC products, giving them an aesthetically pleasing surface finish. Facilitates processing […]

The Core Functions of Stearic Acid in PVC : Lubrication : In PVC, it primarily acts as both an internal and external lubricant, improving melt flow, reducing material viscosity, preventing defects caused by sticking in the machine, and providing good mold release. Thermal Stability : Although stearic acid itself is a fatty acid, it is […]

Key aspects of zinc stearate application in PVC: Heat stabilizer function: As a metal soap stabilizer, it effectively binds to HCl released during processing, delaying PVC decomposition. Initial color inhibition: It significantly improves the transparency and color of the product during initial processing. Synergistic effect: Often used in combination with calcium stearate (Ca/Zn stabilizer) to […]
