Fabric over Foam Gasket is typically a wrap-around foam consisting of conductive fabric or conductive PI (polyimide) encasing sponge or PORON. Its primary feature is its excellent surface conductivity, allowing it to be easily secured with adhesive tape onto shielded components. The products are distinguished by their superior performance and stable structure.

Custom Shape and Size Options
Our company offers a range of custom shapes, including D-shaped, P-shaped, and square configurations.
The all-directional conductive foam is produced using advanced polymer composite foam technology, resulting in uniform cell size, softness, elasticity, and non-shedding properties. This foam evenly distributes to protect device pins and exhibits corrosion resistance, making it an ideal material for long-term device storage. Our latest research and development have produced all-directional conductive foam that can withstand temperatures up to 200°C.

Beryllium Copper Finger Stock is made from beryllium copper alloy and is used as shielding covers to seal gaps between two contact surfaces, providing high EMI shielding effectiveness. Beryllium copper is primarily utilized in various high-performance elastic components, especially where good conductivity, corrosion resistance, abrasion resistance, cold resistance, and non-magnetic properties are required. It is widely used in membrane switches, diaphragms, bellows, and micro switches.
