Parker Chomerics METALASTIC gasketing is a composite EMI and pressure seal in thin sheet form. Shielding is provided by a woven aluminum mesh, and pressure sealing is achieved by neoprene, silicone or fluorosilicone elastomer impregnated in the mesh.
METALASTIC gasketing is intended for use only in applications in which joint unevenness is less than 0.002 in. (0.05 mm), and/or where space is severely limited. The material can be easily cut into gaskets of intricate shapes, and is available with a minimum nominal thickness of 0.016 in. (0.40 mm). These gaskets are not intended to be re-used after joints are opened.
