Product Information
Grafan material is essentially pure carbon in Graphite form processed into a flexible foil material without any fillers, binders or other additives. The product is self lubricating, dimensionally stable, impervious to gases and fluids, and shows exceptional temperature and chemical resistance. Grafan offers unrivalled sealing capabilities under extreme temperature, media and pressure conditions giving extended packing life.
Graphite in this form is self-lubricating with a low coefficient of friction (comparable to Teflon), high thermal conductivity and permanent volumetric elasticity (spring back) which results in no volume reduction (compression set) in use. Resilient with ideal fluid and gas sealing characteristics and extreme capabilities, Grafan offers the ultimate range and performance in a packing material.
Grafan is offered in two standard forms; as Crimped Tape Rolls (VR1 ) or Die-Formed Rings (VR2). We can also supply this Grafan material in the form of a braided packing (Type VR3).
Applications
Extreme condition, long life and zero leakage packing for aII uses up to high temperature, high pressure, high speed applications on pumps, valves, mixers, agitators, expansion joints, ball valve seats and other static seals. Against all acids, alkalis and solvents (except very strong oxidisers), gases, feed water and superheated, or saturated, steam. |
