MIL-DTL-83528 Type A
SSP2569-65 vs. CHO-SEAL 1215

EMI Shielding Silicone with Silver-Copper

SSP2569-65 is an EMI silicone filled with silver-copper particles that is part of the Qualified Product List (QPL) for MIL-DTL-83528 Type A. This product is supplied as fully cured, conductive sheet stock, continuous extrusion profiles, or as ready-to-mold compound. It is tan in color.

CHO-SEAL 1215 Offset

SSP2569-65 can be used instead of CHO-SEAL 1215. CHO-SEAL®  is a registered trademark of Parker Chomerics. SSP also makes other CHOSEAL offsets. SSP is not a Parker Chomerics distributor. We make our own EMI silicones at our Made in USA manufacturing facility and offer a Certificate of Analysis (COA) with every batch. 

MIL-DTL-83528 Type A

SSP2569-65 meets the requirements of the MIL-DTL-83528C Type A specification for silver-plated, copper-filled silicones capable of 110 dB of plane wave shielding effectiveness at 10 GHz with a continuous use temperature range of -55°C to +160°C.
