MBF-G
EnCore® Combined Materials / Mechanically-Bonded Fiber
Material Description:
MBF-G is a high-temperature gasket material combining an inorganic fiber, low binder facing material with an 0.2mm (0.008”) tang perforated tin-plated steel core. This material provides excellent value for exhaust manifold and header gaskets, downpipe and collector gaskets, EGR, muffler, and other exhaust gas applications in automotive and small engines. MBF-G is available in several gauges, with roll widths up to 305mm (12”) wide. The following typical values were established using an overall construction thickness of 1.6mm (0.063”).
