PVC SG-8
PVC SG-8,
eriri eriri akụrụngwa, PVC SG-8 eji maka mmepụta nke mgbidi mgbidi,
The thermoplastic elu-molekul polymer mere site na nkwusioru polymerization nke vinyl chloride monomer.Usoro ihe omimi: - (CH2 - CHCl) n - (N: ogo nke polymerization, N= 590 ~ 1500).Ọ bụ akụrụngwa kachasị ewu ewu nke a na-eji na-emepụta rọba.Ọ nwere ezigbo nkwụsi ike nke kemịkalụ, nguzogide corrosion na nguzogide mmiri.
