Flexible Graphite Gaskets
Flexible graphite gaskets are manufactured from mineral graphite (expandable flake graphite). Flexible Graphite is also called graphite foil. As its name indicates, flexible graphite is flexible and conformable, an ideal property as a gasket material. Flexible graphite can also be used in many other thermal, electronic or electrochemical applications. Works in temperatures up to 950ºF in an oxidizing atmosphere. As a graphite foil gasket supplier, Blaylock Gasket manufactures flexible graphite gaskets & seals including flexible graphite tape, wire tape & flexible graphite sheet.
Main Characteristics and Specs
- Flexible and conformable nature
- Chemical resistant, compatible with most corrosive chemicals
