Cov roj hmab gaskets feem ntau yog tsim los ntawm cov ntaub ntawv xws li NBR (Nitrile Rubber), SBR (Styrene-Butadiene Rubber), HNBR (Hydrogenated Nitrile Rubber), EPDM (Ethylene Propylene Diene Monomer), Silicone, Viton (Fluorocarbon Rubber), CR (Neoprene), CR (Neopreneur).
Ntawm cov kev xaiv no, NBR yog cov khoom siv dav tshaj plaws rau cov roj hmab gaskets, muab tus nqi siab tshaj -kev ua tau zoo. Hloov pauv, FFKM gaskets feem ntau yog tshwj tseg rau cov ntawv thov siab heev- xws li hauv kev lag luam aerospace thiab foob pob hluav taws-vim lawv cov nqi ntau heev; Txawm li cas los xij, lawv qhov kev ua tau zoo tshaj plaws feem ntau tshaj cov khoom siv hlau ntau.
