Onye na-ahụ maka ụfụfụ PVC nwere ịdị arọ molekụla dị elu ma nwee ike melite ike gbazee nke PVC nke ọma. Ọ nwere ike na-ekpuchi gas na-efụ ụfụfụ, mepụta usoro ihe eji ebu mmanụ aṅụ, ma gbochie gas ịgbapụ. Onye na-achịkwa ụfụfụ PVC bụ "ụlọ ọrụ monosodium glutamate", nke a na-eji obere ego eme ihe ma enweghị ike ileda mmetụta ya anya. Ọrụ na àgwà nke ngwaahịa PVC na-emetụta ya kpọmkwem.

N'ozuzu, PVC nhazi ihe enyemaka ACR nwere ike kewaa ụzọ atọ:
1. Ịkwalite plasticization ụdị nhazi ihe enyemaka: Ụdị a na-ejikarị na ngwaahịa PVC siri ike, tumadi na-akwalite plasticization, melite agbaze rheological Njirimara, welie dispersibility nke ndị ọzọ AIDS, na melite o doro anya àgwà nke ngwaahịa. Ejiri ya maka ọtụtụ ngwaahịa PVC dị ka profaịlụ, ọkpọkọ, efere (coils), wdg
2.

N'otu oge ahụ, onye na-ahụ maka ụfụfụ PVC na-abakwa uru maka ịgbasa ihe mgbakwunye ndị ọzọ, gụnyere ndị na-emepụta ụfụfụ, iji meziwanye àgwà elu nke ngwaahịa na ịkwalite glossiness. Ọ dabara maka bọọdụ ịfụfụ, mkpanaka ịfụfụ, ọkpọkọ ụfụfụ, profaịlụ ịfụfụ, plastik osisi na-afụ ụfụ, wdg.
3. Mpụga lubrication ụdị nhazi enyemaka: O nwere otu ihe ahụ dị mma nke na-ewepụ ihe ndị dị na metal dị ka oxidized polyethylene wax, ma ọ dị iche na PVC na ọ nwere ezigbo ndakọrịta. Ọ nwekwara ike ịbawanye arụmọrụ plasticization nhazi ruo n'ókè ụfọdụ, melite agbaze rheological Njirimara, na ịnọgide na-enwe mgbasa mgbasa n'oge extrusion nhazi na-enweghị na-agbanwe ọkụ akpụ arụmọrụ. Ọ na-egbochi mmetụta haze nke mmiri ozuzo na-eme ka mmanu mmanu na ngwaahịa ndị na-apụtaghị ìhè. Kwesịrị ekwesị maka usoro ma ọ bụ akụrụngwa nwere ihe nhazi dị elu, karịsịa mpempe akwụkwọ transperent, profaịlụ ụfụfụ, mbadamba ụfụfụ, na plastik osisi ụfụfụ.
4.
