Polypropylene (PP) yog ib qho thermoplastic semi-crystalline. Muaj ib qho kev ua haujlwm siab, tawv mechanical zog, ua rau ntau hom organic solvents thiab acid-base corrosion.
Nyob rau hauv txoj kev ua lag luam muaj ntau hom kev siv, yog ib qho ntawm cov khoom siv ntau hom polymer. Australian npib kuj yog ua los ntawm polypropylene.
Polypropylene yog lub npe ntawm polypropylene fiber, ua los ntawm propylene li raw cov ntaub ntawv los ntawm polymerization, yaj spinning fibers. Polypropylene teb pib muaj industrial ntau lawm hauv 1957, yog lub hnub qub nce siab hauv cov hluavtaws hluavtaws. Raws li polypropylene muaj cov txheej txheem yooj yim, cov khoom pheej yig, siab zog, qhov sib npaug ntawm cov teeb pom kev zoo, yog li kev loj hlob sai ntawm polypropylene. Tam sim no, polypropylene yog plaub feem ntau ntau hom hluavtaws fibers thiab yog lub teeb pom kev zoo nyob rau hauv hom tshuaj fiber ntau.
