Lub zog ntawm PP nce ntxiv raws li cov ntsiab lus ntawm ethylene nce. Lub Vicat softening kub ntawm PP yog 150 ° C. Vim yog cov qib high school ntawm crystallinity, cov khoom siv no muaj qhov chaw nplaum zoo heev thiab khawb kuj. Tsis muaj ib qho teeb meem ntawm qhov teeb meem hauv PP. Feem ntau, PP yog hloov los ntawm qhov sib ntxiv ntawm cov iav fibers, hlau additives lossis thermoplastic roj hmab. Tus nqi dej ntawm cov PP muaj MFR ib ncua sij hawm ntawm 1 txog 40. Cov khoom tsis tshua muaj MFR PP muaj kev tiv thaiv tsis zoo tab sis qis elongation. Rau cov ntaub ntawv ntawm tib lub MFR, lub zog ntawm hom tshuaj copolymer siab tshaj qhov homopolymer hom. Vim crystallization, tus nqi kwv yees ntawm cov PP yog siab heev, feem ntau 1.8 rau 2.5%. Thiab txoj kev tsis sib haum ntawm kev sib yeem yog qhov zoo dua cov ntaub ntawv xws li PE-HD. Qhov sib ntxiv ntawm 30% iav additive yuav txo qhov shrinkage mus rau 0.7%. Ob homopolymer hom thiab copolymer yam PP cov ntaub ntawv muaj kev nplua nuj ua kom tsis haum, acid thiab alkali corrosion tsis kam, thiab solubility kuj. Txawm li cas los xij, nws tsis tuaj yeem tiv taus cov ntxhuav roj carbonate benzene xws li benzene solvents, cov tshuaj chlorinated hydrocarbons (carbon tetrachloride), thiab cov zoo li. PP tsis muaj oxidation tsis kam ntawm kev kub siab xws li PE.
