polyphylene
Lub zog nqus tshwj xeeb: 0.9-0.91g / cm3 molding shrinkage: 1.0-2.5% molding kub: 160-220 ℃
Qhov ntom ntom nws yog 0.90-0.91g / cm3, uas yog qhov sib zog tshaj plaws ntawm ib qho plastics dav. Cov neeg kho tshuab lub zog, kev coj nruj thiab kev nyuab siab tawg ntawm PP yog txhua qhov siab dua li ntawm HDPE, thiab PP muaj qhov zoo ntawm elongation thiab dabtsi yog khoov nkees tsis kam. Lub rooj noj mov txav tau los ntawm PP tau dhau los ntawm 70 lab khoov kev kuaj uas tsis muaj kev puas tsuaj. Polypropylene muaj cov khoom kub zoo. Nws lub sijhawm siv kub siv ntev ntev npaum li 100oc-120oc, thiab kev siv kub kub tuaj yeem kub txog 150oC thaum tsis muaj thauj khoom. Polypropylene yog tib hom kab mob plastics uas tuaj yeem ua rau hauv rhaub dej thiab tiv taus qhov kub kom tsis muaj menyuam ntawm 135oc.can siv tau rau Cov Khoom Noj Yas Yas, khob hau.
