Conductive Silicone Elastomer
Overview
- Conductive Elastomer, a type of EMI Shielding Gasket, is made by mixing metal powder with silicone rubber and has excellent conductivity.
- Excellent adhesion to adherends due to inherent characteristics of silicone rubber and excellent heat resistance(200℃).
- Used for defense equipment, ships, communication repeaters, defense connectors (O-rings)
Features
- RoHS Compliant
- Excellent hermeticity, conductivity and heat resistance.
