    GORE Power Grade

    GORE Power Grade Sheet is made from 100% expanded PTFE. It provides unequaled chemical inertness, along with a level of high-temperature and blowout resistance. This material will not degrade and offers unlimited shelf life. It conforms to rough sealing surfaces, yet compresses into an extremely tough gasket that makes a tight, long-lasting seal.
