PVC ike ọkpọkọ na usoro nkwadebe ya gụnyere ihe ndị a:
100 polyvinyl chloride resin,
15-25 calcium carbonate;
5-10 titanium oxide;
4-8 mmetụta modifier,
2-5 stabilizer,
0.5-2 mmanụ aṅụ,
2-4 iko sepiolite
3 ~ 8 mejupụtara inorganic ire ere retardant, mejupụtara inorganic ire ọkụ retardant si obere ụwa hydroxide aluminum hydroxide Nkwadebe usoro nke magnesium hydroxide na zinc borate.
Usoro mmepụta:
1) Tinye calcium carbonate titanium oxide n'ime resin POLYvinyl chloride ma gwakọta ya na nnukwu ọsọ maka 3-6min;2) Mgbe ahụ, tinye mmetụta modifier stabilizer, mmanu sepiolite na mejupụtara inorganic ire ọkụ retardant n'ime ngwakọta.

Polyvinyl chloride (PVC) bụ resin thermoplastic linear mepụtara site na polymerization nke vinyl chloride monomer.N'ihi ọdịiche nke akụrụngwa, e nwere ụzọ abụọ nke synthesizing vinyl chloride monomer calcium carbide usoro na mmanụ ala.Sinopec PVC nakweere usoro nkwusioru abụọ, n'otu n'otu sitere na Chinese Shin-Etsu Chemical Company na American Oxy Vinyl Company.Ngwaahịa ahụ nwere ezigbo nguzogide corrosion kemịkalụ, ihe mkpuchi ọkụ eletrik mara mma yana nkwụsi ike kemịkal dị mma.N'ihe dị elu chlorine, ihe ahụ nwere ezigbo nkwụsị ọkụ na ihe na-ekpochapụ onwe ya.PVC dị mfe nhazi site na extrusion, injection ịkpụzi, calendering, ịfụ ịkpụzi, compressing, nkedo ịkpụzi na thermal ịkpụzi, wdg.
