Izinto ezivamile zepuleti lokuhambisa uchungechunge

I-Polyoxymethylene (POM), eyaziwa nangokuthi i-acetal polyacetal, kanye ne-polyformaldehyde, iyi-thermoplastic yobunjiniyela esetshenziswa ezingxenyeni ezinembile ezidinga ukuqina okuphezulu, ukungqubuzana okuphansi kanye nokuqina okuhle kakhulu. Njengakwamanye ama-polymer amaningi okwenziwa, ikhiqizwa izinkampani zamakhemikhali ezahlukene ezinamafomula ahlukene kancane futhi ithengiswa ngezindlela ezahlukene ngamagama anjenge-Delrin, Kocetal, Ultraform, Celcon, Ramtal, Duracon, Kepital, Polypenco, Tenac kanye ne-Hostaform. I-POM ibonakala ngamandla ayo aphezulu, ubulukhuni kanye nokuqina kwayo okufika ku-−40 °C. I-POM imhlophe ngendlela engabonakali kahle ngenxa yokwakheka kwayo okuphezulu kwekristalu kodwa ingakhiqizwa ngemibala ehlukahlukene. I-POM inobuningi obungu-1.410–1.420 g/cm3.

I-Polypropylene (PP), eyaziwa nangokuthi i-polypropene, iyi-polymer ye-thermoplastic esetshenziswa ezinhlobonhlobo zezicelo. Ikhiqizwa nge-polymerization yokukhula kweketanga kusuka ku-monomer propylene. I-Polypropylene ingeyeqembu lama-polyolefin futhi i-crystalline kancane futhi ayiyona i-polar. Izakhiwo zayo zifana ne-polyethylene, kodwa iqinile kancane futhi imelana nokushisa. Iyinto emhlophe, eqinile ngomshini futhi inokumelana okuphezulu kwamakhemikhali.

I-Nylon 6(PA6) noma i-polycaprolactam iyi-polymer, ikakhulukazi i-semicrystalline polyamide. Ngokungafani nezinye izinhlobo eziningi zama-nylon, i-nylon 6 akuyona i-condensation polymer, kodwa kunalokho yakhiwa yi-ring-opening polymerization; lokhu kwenza kube yicala elikhethekile ekuqhathanisweni phakathi kwama-condensation nama-polymer angeziwe.
