Izixhobo zepleyiti yetsheyini yokuhambisa eqhelekileyo

I-Polyoxymethylene (POM), ekwaziwa ngokuba yi-acetal polyacetal, kunye ne-polyformaldehyde, yi-thermoplastic yobunjineli esetyenziswa kwiindawo ezichanekileyo ezifuna ukuqina okuphezulu, ukungqubana okuphantsi kunye nokuzinza okugqwesileyo kobukhulu. Njengakwezinye iipolymers ezininzi zokwenziwa, iveliswa ziinkampani ezahlukeneyo zeekhemikhali ezineefomyula ezahlukeneyo kwaye ithengiswa ngokwahlukeneyo ngamagama anje ngeDelrin, Kocetal, Ultraform, Celcon, Ramtal, Duracon, Kepital, Polypenco, Tenac kunye neHostaform. I-POM ibonakaliswa ngamandla ayo aphezulu, ubulukhuni kunye nokuqina ukuya kuthi ga kwi-−40 °C. I-POM imhlophe engacacanga ngaphakathi ngenxa yokwakheka kwayo okuphezulu kwekristale kodwa inokuveliswa ngemibala eyahlukeneyo. I-POM inobuninzi be-1.410–1.420 g/cm3.

I-Polypropylene (PP), eyaziwa ngokuba yi-polypropene, yi-polymer ye-thermoplastic esetyenziswa kwiintlobo ngeentlobo zezicelo. Yenziwa nge-polymerization ye-chain-growth evela kwi-monomer propylene. I-Polypropylene ikwiqela le-polyolefins kwaye incinci i-crystalline kwaye ayi-polar. Iimpawu zayo zifana ne-polyethylene, kodwa iqinile kancinci kwaye ayitshisi ubushushu. Yinto emhlophe, eqinileyo ngoomatshini kwaye inokumelana okuphezulu kweekhemikhali.

I-Nylon 6(PA6) okanye i-polycaprolactam yi-polymer, ngakumbi i-semicrystalline polyamide. Ngokungafaniyo nezinye ii-nylon ezininzi, i-nylon 6 ayisiyo-condensation polymer, kodwa endaweni yoko yenziwa yi-ring-opening polymerization; oku kuyenza ibe yimeko ekhethekileyo xa kuthelekiswa phakathi kwe-condensation kunye ne-addition polymers.
