Standard Nickel-graphite conductive rubber is used for EMI applications. The rubber is made conductive by incorporating small conductive metal particles throughout the material. It can provide an EMI-proof and watertight seal in narrow constructions. But they are also useful for EMP protection, wave-guide applications and against static electricity.

When in need of high deflection and low closure force we make conductive foams. The material will return to almost its original height when released. The foam is covered with a layer of conductive polyurethane to protect it from environmental influences and to prevent burrs when cutting. Its conductivity is excellent in all directions (X, Y, and Z). Conductive foam is fire retardant as well as RoHS compliant.
