ʻO Polyvinyl chloride (PVC) kahi polymer o vinyl chloride monomer (VCM) i polymerized e ka peroxide, azo compound a me nā mea hoʻomaka ʻē aʻe a i ʻole nā radical polymerization react i hana ma lalo o ka hana o ka mālamalama a me ka wela. Ua kapa ʻia ka vinyl chloride homo polymer a me ka vinyl chloride co polymer.
ʻO ka PVC ka mea nui loa i hana ʻia i loko o ka honua a hoʻohana nui ʻia. Hoʻohana ākea ia i nā mea kūkulu hale, nā huahana ʻoihana, nā pono o kēlā me kēia lā, ka ʻili papahele, nā pōhaku lepo, nā ʻili hana, nā paipu, nā kaula a me nā kaula, nā kiʻi ʻūlū, nā ʻōmole, nā mea huʻi, nā mea hoʻopaʻa, nā olonā a pēlā aku.
