1. Pakuona kwekupisa kupisa,polypropylene heat resistance yakakwira kupfuura polyethylene.Polypropylene yakanyunguduka tembiricha inenge 40% -50% yakakwirira kupfuura polyethylene, anenge 160-170 ℃, saka zvigadzirwa zvinogona sterilized kupfuura 100 ℃, pasina simba rekunze.PP tambo 150 ℃ haina kuremara.Polypropylene inoratidzirwa nekushomeka kwakadzika, hukuru hwemagetsi zvivakwa kune polyethylene uye kusimba kwakasimba.
2. Kune maonero ekudzika kwekushisa kwekudzivirira kuongororwa, kupisa kwekushisa kwepolypropylene kushoma kudarika polyethylene, 0 ℃ simba rekuita ihafu ye20 ℃, uye polyethylene brittle tembiricha inogona kusvika -50 ℃ pazasi;Nekuwedzera kwehuremu hwemamorekuru, hushoma hunogona kusvika -140 ℃.Naizvozvo,kana zvigadzirwa zvinoda kushandiswa munzvimbo yakaderera yekushisa, kanakusvika pazvinobvira kusarudza polyethylene seyakagadzirwa.
3. Pakuona kwekuchembera kuramba, kuchembera kwepolypropylene hakuna simba pane iyo polyethylene.Polypropylene ine chimiro chakafanana ne polyethylene, asi nekuda kwekuti ine cheni yeparutivi inoumbwa nemethyl, zviri nyore kuve oxidized uye kuderedzwa pasi pekuita kweULTRAVIOLET chiedza uye kupisa simba.Mishonga yakawanda yepolypropylene iyo iri nyore kukwegura muupenyu hwezuva nezuva mabhegi akarukwa, ayo ari nyore kuputsika kana akaiswa kuzuva kwenguva yakareba. kushanda kwayo hakuna kunyanya kushamisa, nokuti kune nhamba shomanana yezvisungo zviviri uye ether zvisungo mu polyethylene molecules, kupikisa kwayo kwemamiriro ekunze hakuna kunaka, zuva, mvura inonaya inokonzerawo kukwegura.
4. Kune maonero ekushanduka, kunyange zvazvo polypropylene ine simba rakakwirira, kushanduka kwayo kwakashata, iyo ihwowo husina kunaka hwekudzivisa kubva kune unyanzvi hwemaonero.
