Imathiriyeli yepleyiti yokuhambisa eqhelekileyo

I-Polyoxymethylene (i-POM), eyaziwa ngokuba yi-acetal polyacetal, kunye ne-polyformaldehyde, yi-thermoplastic yobunjineli esetyenziswa kwiindawo ezichanekileyo ezifuna ukuqina okuphezulu, ukukhuhla okuphantsi kunye nozinzo olubalaseleyo lwe-dimensional. Njengezinye iipolymers ezininzi zokwenziwa, iveliswa ziifemu ezahlukeneyo zeekhemikhali ezinefomula eyahlukileyo kancinane kwaye zithengiswa ngokwahlukeneyo ngamagama afana noDelrin, Kocetal, Ultraform, Celcon, Ramtal, Duracon, Kepital, Polypenco, Tenac and Hostaform. I-POM iphawuleka ngokomelela kwayo okuphezulu, ubulukhuni kunye nokuqina kwayo ukuya ku-−40 °C. I-POM i-intrinsically opaque emhlophe ngenxa yokwakheka kwayo okuphezulu kwe-crystalline kodwa inokuveliswa ngemibala eyahlukeneyo.I-POM inobuninzi be-1.410-1.420 g / cm3.

I-Polypropylene (PP), ekwabizwa ngokuba yi-polypropene, Yipolymer ye-thermoplastic esetyenziswa kwiintlobo ngeentlobo zezicelo. Iveliswa nge-chain-growth polymerization ukusuka kwi-monomer propylene.I-Polypropylene yeyeqela le-polyolefins kwaye i-crystalline ngokuyinxenye kunye ne-non-polar. Iipropati zayo zifana ne-topolyethylene, kodwa inzima kancinci kwaye iyamelana nobushushu. Yimathiriyeli emhlophe, enoomatshini kwaye inokumelana nemichiza ephezulu.

Inayiloni 6(PA6) okanye i-polycaprolactam yipolymer, ngakumbi i-semicrystalline polyamide. Ngokungafaniyo nezinye iinayiloni ezininzi, inayiloni 6 ayisiyopolymer yocondensation, kodwa endaweni yoko yenziwe nge-ring-opening polymerization; oku kwenza kube yimeko ekhethekileyo xa kuthelekiswa phakathi kwe-condensation kunye neepolymers ezongezelelweyo.
