ʻO Polyoxymethylene (POM), i ʻike ʻia hoʻi ʻo acetal polyacetal, a me polyformaldehyde, he thermoplastic ʻenekinia i hoʻohana ʻia i nā ʻāpana kikoʻī e koi ana i ka paʻakikī kiʻekiʻe, ka friction haʻahaʻa a me ke kūpaʻa dimensional maikaʻi loa. E like me nā polymers synthetic ʻē aʻe, hana ʻia e nā ʻoihana kemika like ʻole me nā ʻano like ʻole a kūʻai ʻia aku i nā ʻano like ʻole e nā inoa e like me Delrin, Kocetal, Ultraform, Celcon, Ramtal, Duracon, Kepital, Polypenco, Tenac a me Hostaform. Hōʻike ʻia ʻo POM e kona ikaika kiʻekiʻe, paʻakikī a me ka paʻakikī a hiki i −40 °C. He keʻokeʻo opaque ʻo POM ma muli o kona ʻano crystalline kiʻekiʻe akā hiki ke hana ʻia i nā ʻano kala like ʻole. Loaʻa iā POM ka density o 1.410–1.420 g/cm3.

ʻO Polypropylene (PP), i ʻike ʻia hoʻi ʻo polypropene, he polymer thermoplastic i hoʻohana ʻia i nā ʻano hana like ʻole. Hana ʻia ia ma o ka polymerization ulu kaulahao mai ka monomer propylene. No ka hui o polyolefins ʻo Polypropylene a he crystalline hapa a ʻaʻole polar. Ua like kona mau waiwai me ka polyethylene, akā ʻoi aku ka paʻakikī a ʻoi aku ka pale ʻana i ka wela. He mea keʻokeʻo, paʻakikī mechanical a he pale kemika kiʻekiʻe.

He polymer ka Nylon 6(PA6) a i ʻole polycaprolactam, ʻo ia hoʻi ka semicrystalline polyamide. ʻAʻole like me ka hapa nui o nā nylon ʻē aʻe, ʻaʻole ka nylon 6 he polymer condensation, akā ua hana ʻia e ka polymerization ring-opening; ʻo ia ka mea e hoʻolilo ai i mea kūikawā i ka hoʻohālikelike ʻana ma waena o ka condensation a me nā polymers addition.
