Conductive Elastomers Description

Custom CONDUCTIVE ELASTOMERS consist of silicone or fluorosilicone binders with a conductive filler of silver-plated copper, silver-plated aluminum, silver-plated glass, silver, nickel or nickel plated graphite. Custom Shielding offers a complete line of conductive elastomers meeting the requirements of MIL-G-83528. Also available are materials that meet the requirements for commercial applications.

Conductive Elastomers Applications

CONDUCTIVE ELASTOMERS are used in applications requiring maximum shielding in a severe environment. These applications typically include all military and aerospace requirements. These materials can also be applied economically to meet commercial requirements.

Conductive Elastomers Available Configurations

CONDUCTIVE ELASTOMERS are available die-cut, molded or extruded to your specifications or as sheet stock. Reference Page 13 for MIL-G-83528 and other types that are available. The materials listed can also be compounded to meet the requirements for any commercial application. In addition to conductive elastomers, Custom Shielding also offers a complete line of conductive adhesives and sealants.
