Perlast G77X is a specially formulated high-temperature resistant
perfluoroelastomer (FFKM) compound. It is the latest generation of FFKM
which offers outstanding thermal resistance, lower compression set and
enhanced sealing force retention at extreme temperatures.
Perlast® G77X is suitable for both dynamic and static applications and can be
fully moulded into O-rings (any size up to 2.5m/8ft external diameter) and
custom shapes.
Excellent thermal resistance at temperature (up to 350oC short term exposure)
Enhanced physical properties including very low compression set
Meets AMS 7257E requirements
Offers broad chemical resistance in a wide variety of media including acids, caustics, ketones, aldehydes, esters, ethers, alcohols, solvents, sour gases and hydrocarbons (not recommended in severe aqueous, steam and amine applications)
Typical Applications
General purpose use as O-rings or custom sealing component
