DOP ndi pulasitiki yogwiritsidwa ntchito padziko lonse lapansi yomwe imagwiritsidwa ntchito makamaka pokonza utomoni wa polyvinyl chloride, komanso pokonza ma polima ambiri monga ma resin a mankhwala, ma resin a acetic acid, ma resin a ABS, ndi rabara. Ingagwiritsidwenso ntchito popanga utoto, utoto, zotayira, ndi zina zotero.

Chogulitsachi ndi chomwe chimagwiritsidwa ntchito kwambiri mu pulasitiki. Kuwonjezera pa cellulose acetate ndi polyvinyl acetate, chimagwirizana bwino ndi ma resins ambiri opangidwa ndi ma raba ndi ma rabara omwe amagwiritsidwa ntchito mumakampani. Chogulitsachi chili ndi magwiridwe antchito abwino, magwiridwe antchito abwino osakanikirana, magwiridwe antchito apamwamba a pulasitiki, kusinthasintha kochepa, kusinthasintha kwa kutentha kochepa, kukana kutulutsa madzi, magwiridwe antchito apamwamba amagetsi, kukana kutentha bwino komanso kukana nyengo.
DOP:imagwiritsidwa ntchito kwambiri m'mafakitale monga mapulasitiki, rabala, utoto, ndi ma emulsifier. PVC yokhala ndi pulasitiki ingagwiritsidwe ntchito popanga zikopa zopanga, mafilimu a zaulimi, zipangizo zopakira, zingwe, ndi zina zotero.
