Polyvinyl chloride resin SG-8
Iyo thermoplastic yakakwira-molecular polymer yakagadzirwa nekumiswa kwepolymerization yevinyl chloride monomer.The molecular formula :- (CH2 - CHCl) n - (N: dhigirii repolymerization, N= 590 ~ 1500).Ndiyo yakanyanya kuwanda mbishi inoshandiswa mukugadzirwa kwepurasitiki.Iine kugadzikana kwakanaka kwekemikari, kusagadzikana kwekuora uye kusagadzikana kwemvura.
