1. Don mahangar juriyar zafi,polypropylene zafi juriya ya fi polyethylene.Polypropylene narkewa zafin jiki ne game da 40% -50% mafi girma fiye da polyethylene, game da 160-170 ℃, don haka da kayayyakin za a iya haifuwa a fiye da 100 ℃, ba tare da waje karfi.PP igiya 150 ℃ ba maras kyau.Polypropylene yana da ƙarancin ƙarancin ƙima, ingantattun kayan aikin injiniya zuwa polyethylene da ficen rigidity.
2. Domin hangen nesa na low zafin jiki juriya bincike, low zafin jiki juriya na polypropylene ne mai rauni fiye da polyethylene, 0 ℃ tasiri ƙarfi ne kawai rabin 20 ℃, da kuma polyethylene gaggautsa zafin jiki iya kullum isa -50 ℃ kasa;Tare da haɓakar nauyin kwayoyin halitta, mafi ƙarancin zai iya kaiwa -140 ℃.Don haka,idan samfuran suna buƙatar amfani da su a cikin ƙananan yanayin zafi, kokamar yadda zai yiwu a zabi polyethylene a matsayin albarkatun kasa.
3. Don yanayin juriya na tsufa, juriya na tsufa na polypropylene ya fi rauni fiye da na polyethylene.Polypropylene yana da irin wannan tsari zuwa polyethylene, amma saboda yana da sarkar gefe da ta ƙunshi methyl, yana da sauƙi don zama oxidized da ƙasƙanci a ƙarƙashin aikin ULTRAVIOLET haske da makamashin zafi.Abubuwan da aka fi sani da polypropylene waɗanda ke da sauƙin tsufa a rayuwar yau da kullun sune jakunkuna da aka saka, waɗanda ke da sauƙin karyewa lokacin da aka fallasa su zuwa rana na dogon lokaci. aikinsa bai yi fice sosai ba, domin akwai ƴan ƙaramin adadin ɗakuna biyu da ether bond a cikin ƙwayoyin polyethylene, juriyar yanayin sa ba shi da kyau, rana, ruwan sama kuma zai haifar da tsufa.
4. Don ra'ayi na sassauci, ko da yake polypropylene yana da ƙarfin gaske, rashin daidaituwarsa ba shi da kyau, wanda kuma rashin tasiri mai tasiri daga ra'ayi na fasaha.
