I-Polyvinyl chloride resin SG-8
I-thermoplastic high-molecular polymer eyenziwe yi-suspension polymerization ye-vinyl chloride monomer.I-molecular formula :- (CH2 - CHCl) n - (N: degree of polymerization, N= 590 ~ 1500).Yimpahla eluhlaza esetshenziswa kabanzi ekukhiqizeni ipulasitiki.Inokuqina okuhle kwamakhemikhali, ukumelana nokugqwala nokumelana namanzi.
