Lubricants are essential additives in PVC processing. Adding a proper amount of lubricant in PVC can reduce the mutual friction between the particles before the PVC melt and the macromolecules in the PVC melt; reduce the mutual friction between the PVC melt and the plastic mechanical contact surface

Density is a very important index for PVC foaming board. Many customers come to us for lower density but same dosage and mechanical property at the same time. We highly recommend foaming regulator from Shandong Polymer additives, P-530, P-600, P-700.Foaming regulator is a kind of acrylic processing

PVC thermal stabilizer, the other name PVC heat stabilizer, is mainly used for PVC and other chlorine-containing polymers. It was found that PVC can be processed only at above 160 ℃ while it began to thermal decomposition at 120 ~ 130 ℃, release HCl gas, if not inhibit the production of HCl, decompo
