Conductive Rubber

Conductive rubber, also known as conductive elastomer, is made from (silicone) rubber with fillers such as pure silver, silver-coated copper, aluminum, nickel, glass, or graphite. It offers ideal shielding and can also be used for environmental sealing. Conductive rubber can be processed by molding or extrusion: molded rubber can be made into various thicknesses, shapes, and die-cut gaskets, while extruded rubber can be produced in standard cross-sections like rectangles, circles, 'D', 'U', 'P' shapes, and custom profiles.

Material Properties

Silver-Coated Glass (Ag/GI)

Offers the best performance-to-cost ratio, suitable for communication and general military applications.

Silver-Coated Aluminum (Ag/AI)

A basic military-grade padding material, suitable for complex climates with excellent corrosion resistance and electromagnetic pulse protection. High shielding effectiveness and electrochemical compatibility with aluminum enclosures. It has minimal corrosion in salt environments and is lightweight.

Silver-Coated Copper (Ag/Cu)

Provides the best conductivity and EMP resistance, suitable for military use as padding for waveguides and connectors.

Pure Silver (Ag)

Anti-microbial properties, suitable for conditions requiring protection against microbial growth.

Nickel-Coated Graphite (Ni/C)

Cost-effective, good electrochemical compatibility with aluminum, high conductivity, broad frequency shielding, and environmental sealing. Suitable for general military applications.
