Polyvinyl tshuaj dawb (polyvinyl Chloride), yog ib tug yas chloride monomer (yas Chloride Monomer, xa mus rau raws li VCM) nyob rau hauv lub peroxide, azo tebchaw thiab lwm yam initiators, los yog nyob rau hauv qhov kev txiav txim ntawm lub teeb, Thaum tshav kub kub polymerization los ntawm cov dawb radical polymerization mechanism ntawm polymer. Yas chloride polymers thiab yas chloride copolymers yog hu ua yas chloride resins.
PVC yog amorphous qauv ntawm dawb hmoov, ib tug me me degree ntawm cov nyiaj them yug, tus txheeb ze ceev ntawm txog 1.4, iav kub 77, 170 Shan pib decompose nyob ib ncig ntawm [1], cov neeg pluag stability ntawm lub teeb thiab cua sov, nyob rau hauv 100 Shan saum toj no los yog tom qab ib tug ntev lub sij hawm ntawm tshav ntuj raug, yuav decompose thiab tsim hydrogen chloride, thiab ntxiv tsis siv neeg catalytic decomposition, ua heev, lub cev thiab txhua yam khoom no kuj sai txo, nyob rau hauv cov tswv yim daim ntawv sau npe yuav tsum tau ntxiv stabilizer los txhim kho lub stability ntawm tshav kub thiab lub teeb.
Lub molecular ceeb thawj los ntawm PVC nyob rau hauv industrial qhuav yog feem ntau nyob rau hauv lub ntau yam ntawm 50,000 cov hnub, thiab muaj ib tug loj dispersion lub molecular yuag zog nrog lub thawj ntawm polymerization kub, tsis muaj taag melting point, 8008 pib mus soften, 130 Shan hloov mus rau hauv Viscoelastic State, 160 pib hloov mus rau qhov khov-flow lub xeev, zoo txhua yam khoom, tensile lub zog ntawm 60MPa los yog li ntawd, tej yam siv 5a 1010; Rau yav tom ntej dielectric zog.
PVC tau lub ntiaj teb no tus loj tshaj plaws zus tau tej cov general-lub hom phiaj yas, dav siv. Nyob rau hauv lub tsev ntaub ntawv, muaj khoom, txhua hnub necessities, flooring tawv, pem teb vuas, dag tawv, yeeb nkab, hlau thiab cable, ntim zaj duab xis, lam hwj, ua npuas ncauj ntaub ntawv, kev sib khi cov ntaub ntawv, fiber thiab lwm yam yog lug siv.
