Polyvinyl kolorayidi utomoni SG-8
Thermoplastic mkulu-maselo polima wopangidwa ndi kuyimitsidwa polymerization wa vinilu kolorayidi monoma.The molecular formula :- (CH2 - CHCl) n - (N: digiri ya polymerization, N= 590 ~ 1500).Ndizinthu zomwe zimagwiritsidwa ntchito kwambiri popanga pulasitiki.Ili ndi kukhazikika kwamankhwala abwino, kukana dzimbiri komanso kukana madzi.
