Polyvinyl chloride (Polyvinyl chloride), fa'apuupuuga Igilisi PVC, o se polymer o le vinyl chloride monomer (VCM) polymerized e peroxide, azo compound ma isi initiators poʻo lalo o le gaioiga o le malamalama ma le vevela e tusa ai ma le faiga o free radical polymerization..Vinyl chloride homopolymers ma vinyl chloride copolymers o loʻo taʻua faʻatasi o vinyl chloride resins.

PVC o se paʻepaʻe paʻepaʻe ma se fausaga amorphous ma sina tikeri o lala.O le vevela suiga o tioata o le 77 ~ 90 ° C, ma e amata ona pala pe a ma le 170 ° C.E leaga le mautu i le malamalama ma le vevela.I luga aʻe o le 100 ° C poʻo le maeʻa o le susulu o le la i se taimi umi, o le a faʻaleagaina e maua ai le hydrogen chloride, ma faʻateleina ai le faʻaleagaina o le autocatalytic, mafua ai le faʻaleagaina ma le vave faʻaitiitia o mea faaletino ma masini.I faʻatinoga faʻatino, e tatau ona faʻaopoopo mea faʻamautu e faʻaleleia ai le mautu i le vevela ma le malamalama.

Ole mamafa mole mole ole PVC gaosia ile gaosiga e masani lava ile va ole 50,000 i le 110,000.E iai le polydispersity tele.O le mamafa o le mole e faʻateleina i le faʻaitiitia o le vevela polymerization., 160 ~ 180 ℃ amata ona liua i se tulaga tafe viscous;mea tau masini lelei, malosi tensile e uiga i le 60MPa, malosi malosi o le 5 ~ 10kJ/m²;uiga lelei dielectric.

O le PVC sa avea muamua ma palasitika sili ona tele i le lalolagi, ma e faʻaaogaina lautele.E faʻaaogaina lautele i mea faufale, oloa gaosi oloa, mea e manaʻomia i aso uma, paʻu o le fola, fola o le fola, paʻu faʻapitoa, paipa, uaea ma uaea, afifiina ata tifaga, fagu, mea faʻafefe, mea faʻamaufaʻailoga, filo, ma isi.
