Vinyl Chloride-Acetate Copolymer-LW equivalent to WAKER 12E5/65C and France ATO cPA1384
Vinyl chloride-acetate copolymer is produced by international advanced micro-suspension co-polymerization process. As putting vinyl acetate into rigid chain of PVC molecule to make the polarity of PVC molecule reduced and attraction force between molecules lowered, compared with PPVC of homogeneous polymerization, its gelating temperature and molten temperature have been reduced obviously (30-40℃).In addition, because of introducing ester base, it may increase solvent rate between resin and plasticizer, and improve adhesive force between resin and all kinds of adhesion basic material
