He aha ngā momo rerekē o te Polypropylene?
E rua ngā momo matua o te polypropylene e wātea ana: ko ngā homopolymer me ngā copolymer. Ka wehea anō ngā copolymer ki ngā copolymer poraka me ngā copolymer matapōkere. He pai ake te uru o ia kāwai ki ētahi tono i ētahi atu. He maha ngā wā ka kiia te polypropylene ko te "maitai" o te umanga kirihou nā te maha o ngā huarahi ka taea te whakarerekē, te whakarite rānei kia pai ai te whakatutuki i tētahi kaupapa motuhake. Ka tutukihia tēnei mā te whakauru i ngā tāpiringa motuhake ki roto, mā te hanga rānei i tētahi huarahi tino motuhake. He āhuatanga nui tēnei urutau. He taumata whānui te polypropylene homopolymer.

He waeine co-monomer te polypropylene poraka kua whakaritea ki roto i ngā poraka (arā, i roto i tētahi tauira auau) ā, kei roto... -
He aha ngā āhuatanga o te Polyvinyl Chloride (PVC)?
Ko ētahi o ngā āhuatanga tino nui o te Polyvinyl Chloride (PVC) ko: Te Matotoru: He tino matotoru te PVC ki te whakataurite ki te nuinga o ngā kirihou (te taumaha motuhake tata ki te 1.4) Te Ōhanga: He ngāwari te wātea o te PVC, ā, he iti te utu. Te Pakeke: He pai te tūnga o te PVC pakari mō te pakeke me te roa. Te Kaha: He tino kaha te kaha kume o te PVC pakari. He rauemi "thermoplastic" te Polyvinyl Chloride (he rerekē ki te "thermoset"), e pā ana ki te āhua o te urupare a te kirihou ki te wera. Ka wai ngā rauemi thermoplastic i tō rātou ira rewa (he awhe mō te PVC i waenga i te 100 nekehanga Celsius tino iti me ngā uara teitei ake pērā i te 260 nekehanga Celsius i runga i ngā tāpiringa). Ko tētahi āhuatanga matua whai hua mō ngā thermoplastic ko te taea te whakamahana ki tō rātou ira rewa, te whakamatao, me te whakamahana anō...
