Basics knowledge of PVC foaming regulators
date:06.09
A PVC foaming regulator is actually an acrylic resin based processing aid that has all the basic functions of a PVC processing aid, with the difference compared to conventional processing aids. PVC foaming regulator has higher molecular weight and higher viscosityAs a common produ………
Fusion of PVC how promoted by process aids?
date:06.02
Fusion of PVC is promoted by process aids through two mechanisms:1. By improving adhesion in the first step of fusionS-PVC grain (secondary particle) of size 90-250 micron has a hard skin of 0.2 – 1.0 micron. This hard skin makes fusion very difficult. Unless this skin break………
