Polypropylene (PP) waa thermoplastic adag, adag, iyo crystalline ah. Waxaa laga sameeyay propene (ama propylene) monomer. Resin-kan hydrocarbon-ka toosan waa polymer-ka ugu fudud dhammaan balaastikada badeecadaha. PP wuxuu ku yimaadaa homopolymer ama copolymer waxaana si weyn loogu xoojin karaa waxyaabo lagu daro. Waxay ka heshaa isticmaalka baakadaha, baabuurta, alaabta macaamiisha, caafimaadka, filimada la duubay, iwm.
PP waxay noqotay agab la doorto, gaar ahaan marka aad raadineyso polymer leh xoog sare (tusaale ahaan, marka loo eego Polyamide) codsiyada injineernimada ama si fudud u raadineysa faa'iido kharash ah dhalooyinka wax lagu dhejiyo (marka loo eego PET).
