Professional Applications

Dual durometer sponge and solid rubber extrusions made of a rigid composite rubber are designed for advanced sealing applications that require excellent compressibility and structural integrity. These special profiles are the ideal choice for automotive window joints, electrical connections for cabinets, doors of medical equipment, and high – class electrical connections. The unique combination of the effective sealing of soft sponge rubber and the mechanical support of hard rubber makes it an ideal solution for complex industrial applications that require multiple performance characteristics to be achieved in integrated sealing.
