Nga rauemi pereti mekameka kawe noa

Ko te Polyoxymethylene (POM), e mohiotia ana ko te polyacetal acetal, me te polyformaldehyde, He miihini whakamaarama i whakamahia i roto i nga waahanga tika e hiahia ana kia tino pakari, kia iti te waku me te tino pai o te ahua. Pērā me te maha atu o nga polymers waihanga, he mea hanga e nga umanga matū rereke he rereke nga tauira me te hoko rereke ma nga ingoa penei Delrin, Kocetal, Ultraform, Celcon, Ramtal, Duracon, Kepital, Polypenco, Tenac me Hostaform. Ko te POM e tohuhia ana e tona kaha teitei, te pakeke me te pakari ki te -40 °C. He maamaa te POM na te mea he nui te hanga tioata engari ka taea te whakaputa i roto i nga momo tae. He 1.410–1.420 g/cm3 te kiato o te POM.

Ko te Polypropylene (PP), e mohiotia ana ko te polypropene, He polymer thermoplastic e whakamahia ana i roto i te tini o nga momo tono. Ka puta mai ma te polymerization whakatipu mekameka mai i te propylene monomer. No te roopu polyolefins te polypropylene, he kiriataata, he kore-polar. He rite ki te topolyethylene ona ahuatanga, engari he paku uaua ake, he kaha ake te wera. He mea ma, he maataki miihini, he nui te atete matū.

Ko te Nylon 6(PA6) he polycaprolactam ranei he polymer, ina koa te polyamide semirystalline. Kaore i rite ki te nuinga atu o nga nylons, ehara te nylon 6 i te polymer condensation, engari he mea hanga na te polymerization tuwhera whakakai; he mea motuhake tenei mo te whakatairite i waenga i te hauhautanga me nga polymers taapiri.
