Lub luag haujlwm ntawm PVC plasticizer yog txhawm rau txhim kho cov yas thiab yooj yim ntawm PVC (polyvinyl chloride). PVC yog Ameslikas yog ib qho nyuaj thiab nkig polymer, plasticizer yog ntxiv rau lub sijhawm ua haujlwm, cov khoom siv plasticizer tuaj yeem muab tso rau hauv PVC molecular saw, nce qhov kev ncua deb ntawm cov saw molecular, tsis muaj zog ntawm cov saw molecular, thiab txhawb cov hardness ntawm cov saw hlau molecular. Cov khoom siv PVC, txhim kho kev yoog raws, kom nws yooj yim dua rau txheej txheem molding.
Piv txwv li, hauv kev tsim cov yeeb yaj kiab PVC, tawv tawv, hlau thiab cable tawv nqaij thiab lwm yam khoom, ntxiv cov yas tsim nyog tuaj yeem ua rau cov khoom muaj softness thiab elasticity. Cov plasticizers, xws li phthalates, tuaj yeem txhim kho kev ua tau zoo ntawm PVC, yog li nws tuaj yeem siv dav hauv ntau qhov chaw.
