1. Kubireba ubushyuhe bwo kureba,polypropilene irwanya ubushyuhe iruta polyethylene.Ubushyuhe bwa polypropilene buri hejuru ya 40% -50% hejuru ya polyethylene, hafi 160-170 ℃, bityo ibicuruzwa birashobora guhagarikwa hejuru ya 100 ℃, nta mbaraga zituruka hanze.Umugozi wa PP 150 ℃ ntabwo uhinduwe.Polypropilene irangwa nubucucike buke, imiterere yubukorikori isumba polyethylene hamwe no gukomera gukomeye.
2. Kubireba isesengura rito ryo kurwanya ubushyuhe, ubushyuhe buke bwa polypropilene bugira intege nke kurenza polyethylene, 0 strength imbaraga zingaruka ni kimwe cya kabiri cya 20 ℃, kandi ubushyuhe bwa polyethylene burashobora kugera kuri -50 ℃ munsi;Hamwe no kwiyongera kwuburemere bwa molekuline, byibuze birashobora kugera -140 ℃.Kubwibyo,niba ibicuruzwa bigomba gukoreshwa mubushyuhe buke, cyangwauko bishoboka kwose guhitamo polyethylene nkibikoresho fatizo.
3. Kubireba gusaza birwanya gusaza, kurwanya gusaza kwa polypropilene ni intege nke ugereranije na polyethylene.Polypropilene ifite imiterere isa na polyethylene, ariko kubera ko ifite urunigi rwuruhande rugizwe na methyl, biroroshye guhinduka okiside no kwangirika bitewe nigikorwa cya ULTRAVIOLET yumucyo nubushyuhe.Ibicuruzwa bikunzwe cyane bya polypropilene byoroshye gusaza mubuzima bwa buri munsi ni imifuka iboshywe, byoroshye kumeneka iyo ihuye nizuba igihe kirekire.Mu byukuri, kurwanya gusaza kwa polyethylene biruta polypropilene, ariko ugereranije nibindi bikoresho fatizo, imikorere yacyo ntabwo igaragara cyane, kuko hariho umubare muto wububiko bubiri na ether muri molekile ya polyethylene, guhangana nikirere ntabwo ari byiza, izuba, imvura nabyo bizatera gusaza.
4. Kubireba guhinduka, nubwo polypropilene ifite imbaraga nyinshi, ihinduka ryayo ni rito, naryo rikaba rirwanya ingaruka mbi muburyo bwa tekiniki.
