Resin maka imepụta profaịlụ plastik PVC bụ resin polyvinyl chloride (PVC).Polyvinyl chloride bụ polymer nke vinyl chloride monomer mere.

Enwere ike kewaa resin PVC n'ime ụdị abụọ, ụdị rụrụ arụ (XS) na ụdị kọmpat (XJ), dabere na onye na-achụsa ihe na polymerization.The rụrụ urughuru size bụ 0.1-0.2mm, elu bụ oge ụfọdụ, porous, owu-dị ka, mfe banye plasticizer, kọmpat urughuru size bụ ihe na-erughị 0.1mm, elu bụ mgbe niile, siri ike, table tennis, siri ike banye plasticizer, Na ugbu a, a na-eji ụdị ndị ọzọ rụrụ arụ.

Enwere ike kewaa PVC na ọkwa nkịtị (PVC na-egbu egbu) na ọkwa ịdị ọcha (PVC na-adịghị egbu egbu).Ọkwa ịdị ọcha chọrọ ọdịnaya vinyl chloride (VC) nke na-erughị 10 × 10-6, nke enwere ike iji na nri na ọgwụ.Dị iche iche sịntetik usoro, PVC nwere ike kewaa nkwusioru PVC na emulsion PVC.Dị ka ọkọlọtọ mba GB/T5761-93 "Nleba ọkọlọtọ maka izugbe-nzube polyvinyl chloride resin maka nkwusioru usoro", PVC nkwusioru usoro na-ekewa n'ime PVC-SG1 ka PVC-SG8 asatọ ụdị resins, ebe nke nta na ọnụ ọgụgụ. ka ogo nke polymerization dị ukwuu, ịdị arọ molekụla na-adịkwa ka ike dị ukwuu, nke na-agbaze agbaze, na-esiwanye ike nhazi.
