PP resin yog dab tsi?
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. Polypropylene kuj hu ua polypropene, yog cov thermoplastic polymer siv nyob rau hauv ntau yam kev siv. Nws yog tsim los ntawm saw-loj hlob polymerization los ntawm monomer propylene.Polypropylene belongs rau pawg ntawm polyolefins thiab yog ib nrab crystalline thiab tsis-polar. Nws cov khoom zoo ib yam li polyethylene, tab sis nws yog ib qho nyuaj me ntsis thiab ua kom sov dua. Nws yog ib qho dawb, cov khoom siv rugged thiab muaj tshuaj lom neeg ua haujlwm siab.
