MCC-A
EnCore® Combined Materials / Mechanically Clad Fiber
Material Description:
MCC-A is a high performance gasket material combining an inorganic fiber-based core with 0.2mm (0.008 ) perforated tin-plated steel facings on one or both sides. It is ideally suited for high temperature applications including exhaust manifold and header gaskets, engine heat shields, furnace and HVAC shielding, and small engine head and muffler gaskets. MCC-A is thermally stable and can be used to seal hot gases up to 760°C (1400°F) when properly clamped between flanges. The typical values below were established using only the fiber core without cladding, with a thickness of 1.0mm (0.039 ). Double-clad material is available in 1.2mm (0.047 ) and 1.6mm (0.062 ) thicknesses, and single clad material is available in 1.0mm (0.039 ) and 1.2mm (0.047 ) thicknesses.
