PP resin yog dab tsi?
Polypropylene (PP) yog ib yam khoom siv thermoplastic uas tawv, 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. Polypropylene tseem hu ua polypropene, yog cov thermoplastic polymer siv rau ntau yam kev siv. Nws yog tsim los ntawm kev loj hlob ntawm cov saw hlau polymerization los ntawm monomer propylene. Polypropylene yog ib feem ntawm pawg polyolefins thiab yog ib feem crystalline thiab tsis yog polar. Nws cov khoom zoo ib yam li polyethylene, tab sis nws nyuaj me ntsis thiab tiv taus cua sov ntau dua. Nws yog cov khoom dawb, mechanically rugged thiab muaj kev tiv taus tshuaj lom neeg siab.
