Nā hiʻohiʻona
ʻO ka plastik PVC "polyvinyl chloride plastic", he pauka keʻokeʻo, ka huahana i hana nui ʻia e ka polymerization o ka vinyl chloride monomer, a hoʻohui i nā mea ʻē aʻe e hoʻonui ai i ka pale wela, ka paʻakikī a me ka ductility, ʻo ia kekahi o nā thermoplastic maʻamau. ʻO ka anti-corrosion, ikaika a paʻa hoʻi, ʻo ia hoʻi ke ahi (Flame retardant value ≥40), High chemical resistance (sulfuric acid's concentration 90%, Nitric acid's concentration 60% and Sodium hydroxide's concertration 20%), maikaʻi loa ka ikaika mechanical a me ka Insulation maikaʻi. Akā ʻoi aku ka maikaʻi o ke kūpaʻa māmā a me ka pale wela (kahi palupalu 80 ℃, inā ʻoi aku ka mahana ma mua o 130 ℃, e loli ke kala a puka mai i ka HCI), no laila pono mākou e hoʻohui i ka stabilizer e hoʻomaikaʻi i ke kūpaʻa māmā a me ka pale wela ke hoʻohana ʻia.
