General Properties and Applications

The GAMBIT MAGNUM sealing plate is a composite of specially selected fibers, fillers, and rubber. The use of high-performance aramid and mineral fibers, nanofillers, and a unique rubber composition (forming the discontinuous phase), as well as a specific cross-linking method, give the structure distinct characteristics compared to standard fiber-–elastomeric gasket sheets.

Seals made from this sheet retain greater flexibility at elevated temperatures and offer increased resistance to media compared to standard sealing sheets, which translates into a longer service life.

Material

The GAMBIT MAGNUM gasket sheet is made from:

• KEVLAR® aramid fibers
• mineral fibers
• fillers / nanofillers

The components are bound together with an HNBR rubber-based binder.
