Alaabta silsiladda gudbiyaha ee caadiga ah

Polyoxymethylene (POM), oo sidoo kale loo yaqaan acetal polyacetal, iyo polyformaldehyde, waa thermoplastic injineernimo oo loo isticmaalo qaybaha saxda ah ee u baahan adkaansho sare, is jiidjiid hoose iyo xasillooni cabbir oo aad u fiican. Sida polymers kale oo badan oo isku-dhafan, waxaa soo saara shirkado kiimiko oo kala duwan oo leh qaacidooyin yar oo kala duwan waxaana si kala duwan loogu iibiyaa magacyo sida Delrin, Kocetal, Ultraform, Celcon, Ramtal, Duracon, Kepital, Polypenco, Tenac iyo Hostaform. POM waxaa lagu gartaa xooggeeda sare, adkaanteeda iyo adkaanteeda ilaa −40 °C. POM waa caddaan aan caddayn sababtoo ah halabuurka kristalinta sare laakiin waxaa lagu soo saari karaa midabyo kala duwan. POM waxay leedahay cufnaan dhan 1.410–1.420 g/cm3.

Polypropylene (PP), oo sidoo kale loo yaqaan polypropene, waa polymer thermoplastic ah oo loo isticmaalo codsiyo kala duwan. Waxaa lagu soo saaraa polymerization-ka koritaanka silsiladda ee ka yimaada monomer propylene. Polypropylene waxay ka tirsan tahay kooxda polyolefins waana qayb ahaan kristaliin ah oo aan polar ahayn. Sifooyinkeedu waxay la mid yihiin topolyethylene, laakiin way xoogaa adag tahay oo kulaylka ayay u adkaysataa. Waa walax cad oo farsamo ahaan adag waxayna leedahay iska caabin kiimiko oo sareysa.

Nylon 6(PA6) ama polycaprolactam waa polymer, gaar ahaan semicrystalline polyamide. Si ka duwan inta badan nayloonada kale, naylon 6 maaha polymer condensation, laakiin waxaa sameeya polymerization-ka furitaanka giraanta; tani waxay ka dhigaysaa kiis gaar ah marka la barbar dhigo polymers-ka condensation iyo isku darka.
