Polypropylene (PP) ndi chiyani?
Polypropylene (PP) ndi thermoplastic yolimba, yolimba, komanso yonyezimira. Amapangidwa kuchokera ku propene (kapena propylene) monomer. Utoto wa hydrocarbon uyu ndiye polima wopepuka kwambiri pakati pa mapulasitiki onse ogulitsa. PP imabwera ngati homopolymer kapena ngati copolymer ndipo imatha kulimbikitsidwa kwambiri ndi zowonjezera. Imapeza ntchito pakuyika, magalimoto, ogula zabwino, zamankhwala, mafilimu oponyedwa, etc. PP yakhala chinthu chosankha, makamaka mukafuna polima yokhala ndi mphamvu zopambana (mwachitsanzo, vs Polyamide) pamapulogalamu aukadaulo kapena kungoyang'ana mtengo wopindulitsa m'mabotolo owumba (vs. PET). -
