Polyoxymethylene (POM), yomwe imadziwikanso kuti acetal polyacetal, ndi polyformaldehyde, ndi engineering thermoplastic yomwe imagwiritsidwa ntchito m'zigawo zolondola zomwe zimafuna kuuma kwakukulu, kugundana kochepa komanso kukhazikika kwapang'onopang'ono. Monga ma polima ena ambiri opangira, amapangidwa ndi makampani osiyanasiyana opanga mankhwala okhala ndi mitundu yosiyana pang'ono ndipo amagulitsidwa mosiyanasiyana ndi mayina monga Delrin, Kocetal, Ultraform, Celcon, Ramtal, Duracon, Kepital, Polypenco, Tenac ndi Hostaform. POM imadziwika ndi kulimba kwake, kuuma kwake komanso kulimba kwake mpaka -40 °C. POM ndi yoyera yowoneka bwino chifukwa cha mawonekedwe ake apamwamba a crystalline koma amatha kupangidwa mumitundu yosiyanasiyana.POM imakhala ndi makulidwe a 1.410-1.420 g/cm3.

Polypropylene (PP), yomwe imadziwikanso kuti polypropene, Ndi polima ya thermoplastic yomwe imagwiritsidwa ntchito m'njira zosiyanasiyana. Amapangidwa kudzera mu unyolo-kukula kwa polymerization kuchokera ku propylene monoma. Makhalidwe ake ndi ofanana ndi topolyethylene, koma ndizovuta pang'ono komanso zosatentha kwambiri. Ndi chinthu choyera, chopangidwa ndi makina ndipo chimakhala ndi kukana kwa mankhwala.

Nylon 6(PA6) kapena polycaprolactam ndi polima, makamaka semicrystalline polyamide. Mosiyana ndi ma nayiloni ena ambiri, nayiloni 6 si polymer ya condensation, koma m'malo mwake imapangidwa ndi polymerization yotsegula; izi zimapangitsa kuti ikhale yapadera poyerekezera pakati pa condensation ndi ma polima owonjezera.
