9400 Carbon/PTFE Gaskets
DURLON® 9400 gasket material is a high performance filled PTFE gasket designed for use in piping and equipment in chemical, pharmaceutical, food and other general industrial applications where resistance to highly aggressive chemicals (including hydrofluoric acid) is required. Style 9400 conforms to FDA requirements.
It can also be used as gasketing for anhydrous hydrogen fluoride (AHF) in railroad tankcars and in plants as a material of construction where barium sulfate filled PTFE may not prove suitable.
DURLON® 9400 is made of pure PTFE resins combined with carbon fillers homogeneously dispersed throughout the compound. DURLON® 9400 does not exhibit the cold flow problems associated with virgin PTFE yet has excellent sealability, flexibility, non-sticking and cutting characteristics. DURLON® 9400 also demonstrates good electrical conducting properties.
