Flexible Graphite - Seals like no other sealing material.
Flexible graphite will handle higher temperatures than any
elastomeric of non-asbestos gasketing and handle a ph range from
0-14.Developed originally by Union Carbide under the brand
name "Grafoil". Flexible graphite solves industries difficult
sealing applications.
