 | 1. Cov Khoom Ua Ntej Polypropylene (PP) muaj kev nruj zoo dua li polyethylene (PE). Lub flexural modulus ntawm PP yog li 1.52Gpa, PE tsuas yog 207Mpa, thiab cov xeb tshuaj lom neeg zoo ib yam li PE; |
2. Lub khob hloov kub ntawm polypropylene qis dua chav tsev kub, qhov cuam tshuam tiv taus yog zoo dua PS, thiab piv nrog nyuaj rov qab tsim ntawm PS npaus, polypropylene ua npuas dej yog qhov khoom siv ib puag ncig; |  |
 | 3. Polypropylene muaj qhov kub tsis txaus ntseeg qhov kub thiab tuaj yeem siv hauv qee qhov siab kub teb. Ua npuas polypropylene feem ntau tuaj yeem tiv taus qhov kub thiab txias ntawm 130 ° C, uas yog ntau siab tshaj qhov siab tshaj plaws siv kub ntawm polyethylene ua npuas dej, uas yog 80 ° C. Lub xovtooj kaw kev teeb tsa ua nws cov thermal conductivity los ntawm cuam tshuam los ntawm noo noo, yog li nws muaj peev xwm siv ua cov khoom siv rwb thaiv tsev thermal; |
4. zoo tsis kub cov yam ntxwv: Cov khoom lag luam qhia tau zoo txawm nyob ntawm -30 ℃. |  |
