Polyethylene CAS 9002-88-4
He hauwaiwai kua kōkō te polyethylene, he rite te hanganga ki te paraffin, he rauemi hangai taumaha-ngota teitei i hangaia mā te whakakotahi i te ethylene. Kāore he ira pōrari o ngā ngota polyethylene, he iti te mimiti wai, ā, he pai te pumau. Kāore e rewa i roto i ngā whakarewa noa i te pāmahana rūma, he pumau ki ngā waipiro, ngā ether, ngā ketone, ngā esters, ngā waikawa ngoikore, me ngā turanga ngoikore. Engari ka pupuhi i roto i ngā hauwaiwai ngako, ngā hauwaiwai kakara, me ngā hauwaiwai halogenated, ka waikurahia e ngā waikawa kaha kei roto te hāora, ā, ka waikurahia ina werahia, ina whakamāramahia rānei i te hau.
