Looking for CHO-SEAL® EMI gasket offsets*? SSP makes EMI silicones and fabricates EMI gaskets.
Specialty Silicone Products (SSP) makes EMI shielding elastomers that offer alternatives to Parker Chomerics CHO-SEAL products. We invite you to compare our EMI silicones to products you may be buying elsewhere.
Why buy EMI shielding silicones from SSP? For starters, we offer low minimum order quantities (MOQs), have short lead times, and sell to your directly.
Plus, many of SSP’s offsets to CHO-SEAL® products meet MIL-DTL-83528 (M83528) requirements, a U.S. military specification for electrically conductive elastomeric gaskets that provide specific levels of EMI shielding. SSP can even fabricate EMI gaskets in M83528 slash sizes, including EMI O-rings.
Importantly, the MIL-DTL-83528 conductive silicones that SSP manufactures and fabricates are part of the M83528 Qualified Products List (QPL) from the Defense Logistics Agency, which is part of the U.S. Department of Defense. These M83528 QPL certified materials are proudly Made in the USA.
