PP pawg thawj coj saibyog cov khoom siv semi-crystalline. Nws yog ib qho nyuaj thiab muaj qhov melting point ntau dua li PE. Vim hais tias homopolymer PP kub yog nkig siab tshaj 0C, ntau cov khoom lag luam PP yog random copolymer nrog 1 txog 4% ethylene los yog clamp copolymer nrog cov ntsiab lus ethylene siab dua. Me me, yooj yim rau vuam thiab txheej txheem, nrog cov tshuaj tiv thaiv zoo tshaj, tiv thaiv tshav kub thiab cuam tshuam, tsis muaj tshuaj lom thiab tsis qab, nws yog ib qho ntawm cov khoom siv hluav taws xob PP uas ua tau raws li kev tiv thaiv ib puag ncig. Cov xim tseem ceeb yog xim dawb, microcomputer xim, thiab lwm yam xim kuj tuaj yeem kho raws li cov neeg siv khoom xav tau. Daim ntawv thov ntau yam: acid thiab alkali resistant khoom.
Iav fiber reinforced PP board (FRPP board): Tom qab tau txhawb los ntawm 20% iav fiber ntau, ntxiv rau kev tswj hwm qhov kev ua tau zoo tshaj plaws, lub zog thiab rigidity yog ob npaug piv nrog PP, thiab nws muaj cov cua sov zoo thiab qhov kub thiab txias tsis kam, Anti-corrosion arc kuj, qis shrinkage. Tshwj xeeb tshaj yog tsim rau cov tshuaj fiber ntau, chlor-alkali, roj av, dyestuff, tshuaj tua kab, zaub mov, tshuaj, lub teeb kev lag luam, metallurgy, dej phwj tuaj kho thiab lwm yam kev lag luam.
PPH pawg thawj coj saib, beta (β)-PPHib leeg-sided non-woven board. (β)-PPH cov khoom lag luam muaj cov cua sov zoo thiab cov pa oxygen aging, lub neej ua haujlwm ntev thiab cov khoom siv zoo. Nws tau ua tiav zoo siv hauv kev tsim cov phaj, thiab cov cuab yeej siv siab heev belongs rau txoj haujlwm ua hauv Suav teb. Cov khoom siv no tuaj yeem siv rau cov ntawv lim dej thiab cov thawv ntim cov kab mob, rau cov iav fiber reinforced yas winding hauv ob sab phlu, petrochemical kev lag luam cia, kev thauj mus los thiab kev tiv thaiv corrosion, fais fab nroj tsuag, dej siv, kev kho dej thiab cov kav dej rau cov nroj tsuag dej; thiab cov nroj tsuag steel, fais fab nroj tsuag tshem tawm plua plav, ntxuav thiab cua tshuab, thiab lwm yam.
