Style 1308Flexible Graphite Sheet

Product Line Sheet

Construction/ Description

Style 1308 flexible graphite sheet is made from exfoliated graphite flake which is compressed into foil by a carefully controlled calendaring process. In this process, the expanded flake particles are mechanically locked together without the use of fibers, binders, or other additives. The sheets are then adhesively bonded and laminated to the required thickness.

Application / Service

Flexible graphite sheet has pressure-temperature sealability capabilities that are far superior to all asbestos reinforced and non-asbestos reinforced sheet products. It is resistant to chemical attack by virtually all organic and inorganic fluids with the exception of concentrated, highly oxidizing acids.

Gaskets cut from flexible graphite sheet seal with low to moderate bolt loads. Re-torquing is rarely required due to very low creep relaxation. Flexible graphite conforms to irregular flange sealing surfaces and readily flows into flange irregularities enabling it to seal both smooth and coarse surface finishes.
