PVC SG-8
Thermoplastic high-molecular polymer e entsoeng ke ho fanyeha polymerization ea vinyl chloride monomer.Thepa ea molek'hule :- (CH2 – CHCl) n – (N: tekanyo ea polymerization, N= 590 ~ 1500).Ke thepa e tala ka ho fetisisa e sebelisoang tlhahisong ea polasetiki.E na le botsitso bo botle ba lik'hemik'hale, ho hanyetsa kutu le ho hanyetsa metsi.
