Gambit MAGNUM® Gasket Sheet

Series: GAMBIT AF High

The Gambit MAGNUM® gasket sheet is an advanced composite consisting of carefully selected fibers, fillers, and rubber. By using high-performance aramid and mineral fibers, as well as innovative nanofillers, it provides exceptional performance. Its unique structure, where rubber forms a discontinuous phase, and the specific cross-linking method give it a different character compared to standard fiber-elastomer sheets. Seals made from this sheet exhibit greater flexibility at elevated temperatures and increased resistance to media, significantly extending their service life.

GAMBIT AF High gasket sheets are a product with the highest performance parameters, made from top-quality materials, ensuring technical stability, long service life, and excellent sealing properties.
