Zvinhu zveplate zve conveyor chain plate zvakajairika

Polyoxymethylene (POM), inozivikanwawo seacetal polyacetal, uye polyformaldehyde, ipurasitiki yeinjiniya inoshandiswa muzvikamu zvakanyatsonaka zvinoda kuomarara kwakanyanya, kukweshana kwakaderera uye kugadzikana kwakanaka kwazvo. Sezvakaita mamwe mapolymer akawanda ekugadzira, inogadzirwa nemakambani akasiyana emakemikari ane mafomura akasiyana zvishoma uye inotengeswa zvakasiyana-siyana nemazita akadai seDelrin, Kocetal, Ultraform, Celcon, Ramtal, Duracon, Kepital, Polypenco, Tenac naHostaform. POM inozivikanwa nekusimba kwayo kwakanyanya, kuomarara uye kuomarara kusvika -40 °C. POM yakachena isina kujeka nekuda kwekugadzirwa kwayo kwakawanda kwekristalline asi inogona kugadzirwa nemavara akasiyana-siyana. POM ine density ye1.410–1.420 g/cm3.

Polypropylene (PP), inozivikanwawo se polypropene, ipolymer yethermoplastic inoshandiswa mumhando dzakasiyana-siyana. Inogadzirwa kuburikidza ne polymerization ye chain-growth kubva ku monomer propylene. Polypropylene iri muboka re polyolefins uye ine crystalline zvishoma uye isiri polar. Hunhu hwayo hwakafanana ne polyethylene, asi yakaoma zvishoma uye inodzivirira kupisa. Ichinhu chichena, chakasimba uye ine resistance yakakura yemakemikari.

Nylon 6(PA6) kana polycaprolactam ipolymer, kunyanya semicrystalline polyamide. Kusiyana nemamwe manylon akawanda, nylon 6 haisi condensation polymer, asi inoumbwa ne ring-opening polymerization; izvi zvinoita kuti ive nyaya yakakosha mukuenzanisa condensation ne addition polymers.
