Polypropylene (PP) yog ib qho tawv, tawv, thiab crystalline thermoplastic. Nws yog tsim los ntawm propene (los yog propylene) monomer. Qhov no linear hydrocarbon resin yog lub lightest polymer ntawm tag nrho cov khoom yas. PP tuaj yeem ua homopolymer lossis ua copolymer thiab tuaj yeem txhawb nqa zoo nrog cov khoom ntxiv. Nws pom daim ntawv thov hauv ntim, tsheb, neeg siv khoom zoo, kev kho mob, cam khwb cia zaj duab xis, thiab lwm yam.
PP tau dhau los ua cov khoom ntawm kev xaiv, tshwj xeeb tshaj yog thaum koj tab tom nrhiav rau cov khoom siv polymer nrog lub zog zoo (xws li, vs Polyamide) hauv kev siv engineering lossis tsuas yog nrhiav tus nqi kom zoo dua hauv lub tshuab molding fwj (vs. PET).
