Conductive Elastomers
 
Effective Shielding Co. provides a wide selection of conductive elastomers to ensure a successful galvanic compatibility with any emi gasket. Conductive elastomers are composed of fine micro particles that are compounded into a high-grade silicone or EPDM, providing excellent EMI/RFI shielding and an environmental seal for all applications.  Elastomers ensure that electronic components within connected applications are compatible, as well as preventing resistance between joined surfaces.
To choose the appropriate conductive elastomer for your emi gasket, you will need to evaluate what type of environment the application will be used in.  If there is little to no risk of environmental threat, such as water or dust, we recommend you choose from our nickel coated graphite options.  These materials are less expensive and extremely resilient when used in controlled surroundings.
If your application encounters numerous environmental threats, you should consider selecting from our Silver Plated elastomers.  Through many proven tests, silver has demonstrated to be one of the most robust and long-lasting metals, standing up to nearly every imaginable environmental threat.
All emi gasket materials are available in molded sheets, strips, die cut, or extruded forms.
