Polypropylene (PP) yog ib yam khoom siv thermoplastic uas ruaj khov, tawv, thiab siv lead ua. Nws yog ua los ntawm propene (lossis propylene) monomer. Cov roj hydrocarbon linear no yog cov polymer sib dua ntawm txhua yam khoom yas. PP los ua homopolymer lossis copolymer thiab tuaj yeem ua kom muaj zog nrog cov khoom ntxiv. Nws pom daim ntawv thov hauv kev ntim khoom, tsheb, khoom siv rau cov neeg siv khoom, kev kho mob, cov yeeb yaj kiab cam khwb cia, thiab lwm yam.
PP tau dhau los ua cov khoom siv xaiv, tshwj xeeb tshaj yog thaum koj tab tom nrhiav cov polymer uas muaj zog dua (piv txwv li, piv rau Polyamide) hauv kev siv engineering lossis tsuas yog nrhiav qhov zoo dua tus nqi hauv cov fwj tshuab molding (piv rau PET).
