What are the differences between PVC processing aids, plasticizers, and lubricants？
Because PVC processing aids are highly compatible with PVC and have a high relative molecular weight (about (1-2) × 105-2.5 × 106g/mol) and no coating powder, they are subject to heat and mixing during the molding process. They first soften and tightly bond the surrounding resin particles. T...
