Elastomer Core Mesh
Elastomer core mesh is an optimum solution for combining excellent shielding performance with a high degree of elasticity. Both qualities are guaranteed by the construction of the gasket which consists of an elastomer core with two layers knitted wire mesh. Typically, elastomer core mesh is used for doors and enclosures with low closing force as well as for sheet metal and molded enclosures. Attaching the gaskets is simply done by pressing or gluing the gasket into the groove.
