Ezinye zezona mpawu zibalulekileyo ze-polypropylene zezi:
1. Ukumelana neekhemikhali: Iisiseko kunye neeasidi ezixutyiweyo azisabela ngokukhawuleza kwi-polypropylene, nto leyo eyenza ukuba ibe lukhetho olufanelekileyo kwizikhongozeli ezinezinto ezinjalo, ezifana nezinto zokucoca, iimveliso zoncedo lokuqala, nokunye.
2. Ukuthamba kunye nokuqina: I-Polypropylene iya kusebenza ngokuthamba kuluhlu oluthile lokuphambuka (njengazo zonke izinto), kodwa iya kuba nokuthamba kweplastiki kwasekuqaleni kwenkqubo yokuguquguquka, ngoko ke ngokubanzi ithathwa njengezinto "eziqinileyo". Ukuqina ligama lobunjineli elichazwa njengokukwazi kwezinto ukuthamba (ngokweplastiki, kungekhona ngokuthamba) ngaphandle kokuqhekeka.
3. Ukumelana nokudinwa: I-Polypropylene igcina imo yayo emva kokuguqa kakhulu, ukugoba, kunye/okanye ukugoba. Le propati ixabiseke kakhulu ekwenzeni iihinge eziphilayo.
4. Ukufakwa kwe-insulation: i-polypropylene inokumelana kakhulu nombane kwaye iluncedo kakhulu kwizinto ze-elektroniki.
5. Ukudluliselwa kokukhanya: Nangona iPolypropylene inokwenziwa ibonakale, idla ngokuveliswa ukuba ingabonakali ngokwendalo. IPolypropylene ingasetyenziselwa usetyenziso apho ukudluliselwa kokukhanya kubalulekile okanye apho ixabiso layo liphezulu. Ukuba ukudluliselwa kokukhanya kufuneka kube phezulu, iiplastiki ezifana neAcrylic okanye iPolycarbonate zezona zikhetho zingcono.
I-Polypropylene ihlelwa njengesixhobo "se-thermoplastic" (ngokuchaseneyo ne-"thermoset") esinxulumene nendlela iplastiki esabela ngayo kubushushu. Izinto ze-thermoplastic ziba lulwelo kwindawo yazo yokunyibilika (malunga ne-130 degrees Celsius kwimeko ye-polypropylene).
Uphawu olubalulekileyo olusebenzayo malunga nee-thermoplastics kukuba zinokufudunyezwa zide zifikelele kwinqanaba lazo lokunyibilika, zipholiswe, kwaye ziphinde zifudunyezwe kwakhona ngaphandle kokuwohloka okukhulu. Endaweni yokutsha, ii-thermoplastics ezifana ne-polypropylene ziyanyibilika, nto leyo evumela ukuba zifakwe ngokulula zize ziphinde zisetyenziswe.
Ngokwahlukileyo koko, iiplastiki ze-thermoset zinokufudunyezwa kube kanye kuphela (ngesiqhelo ngexesha lenkqubo yokubumba ngenaliti). Ukufudumeza kokuqala kubangela ukuba izinto ze-thermoset ziqine (ezifana ne-epoxy enamacandelo ama-2) nto leyo ebangela utshintsho lweekhemikhali olungenakujikwa. Ukuba uzama ukufudumeza iplastiki ye-thermoset kubushushu obuphezulu okwesibini, iya kutsha nje. Olu phawu lwenza izinto ze-thermoset zingabi namdla wokuphinda zisetyenziswe.
