Ụfọdụ okwu gbasara polyethylene chlorinated:

Chlorinated polyethylene (CPE) bụ ihe polymer juru eju nke nwere ọdịdị ntụ ntụ ọcha, adịghị egbu egbu na enweghị isi. Ọ nwere ezigbo nguzogide ihu igwe, nguzogide ozone, nguzogide kemịkalụ, na nguzogide ịka nká, yana ezigbo nguzogide mmanụ, ire ọkụ na ihe ndị na-agba agba. Ọdịmma siri ike (ka na-agbanwe na -30 ℃), ezigbo ndakọrịta na ihe ndị ọzọ polymer, oke decomposition okpomọkụ, ire ere na-emepụta HCL, nke nwere ike ime ka mmeghachi omume dechlorination nke CPE.
