Cov ntaub ntawv nquag rau cov khoom lag luam suav nrog cov hauv qab no:
Roj hmab muaj roj hmab: cov roj hmab ntuj raug rho tawm los ntawm Lasx sau los ntawm cov ntoo roj hmab, thiab nws cov khoom sib xyaw tseem ceeb yog CIS-polyisoprene. Nws muaj elasticity zoo, tensile muaj zog thiab kua muag tiv, thiab yog siv dav hauv cov khoom lag luam roj hmab xws li log tsheb thiab tapes. Cov roj hmab muaj cov roj hmab muag ntawm cov kub, tab sis crystallizes thiab hamens ntawm tsawg kub, thiab tsis tiv taus cov kua qaub muaj zog.
Cov roj hmab hluavtaws: roj hmab hluavtaws yog cov khoom siv tshuaj, thiab muaj cov yam ntxwv ntawm cov huab cua zoo, thiab cov roj ua kom zoo, kub tsis kam thiab kub tsis kam. Cov roj hmab hluavtaws ntau yam suav nrog cov roj hmab styrene-butadiene roj hmab (iir), ethylene-diene roj hmab (EPDM) thiab nitrile roj hmab (ကantrile roj hmab (epdr Cov ntaub ntawv no tau siv dav hauv kev lag luam, xws li cov log tsheb, cov menyuam conveyor, ntsaws ruaj ruaj, thiab lwm yam.
Cov roj hmab silicone roj hmab: lub ntsiab ntawm cov roj hmab silicone yog muaj los ntawm lwm silicone thiab oxygen atoms, thiab ob pawg oliro tau txuas rau ntawm silicon atom. Nws muaj cov kub zoo heev thiab tau siv dav hauv cov xwm txheej uas yuav tsum muaj cov khoom kub siab, xws li cov ntaub ntawv kub siab thiab insulating.
Fluororubber: Fluororubber muaj cov cua txias zoo heev thiab yog qhov haum rau kev sib khi thiab hnav-resistant qhov chaw nyob rau hauv cov kev kub kub siab. Nws cov qauv mis feem ntau suav nrog fluororubub, vulcanizing tus neeg sawv cev, hla kev sib txuas, sib xyaw ua ke muab tub lim, thiab lwm yam.
