Stockwell Elastomerics, Inc. now provides .020" and .032” thick Fabric Reinforced Nickel-Graphite Filled Conductive Silicone Rubber for EMI Shielding Gaskets with narrow cross sections. The fabric reinforcement enhances durability and dimensional stability in filled conductive silicone elastomers that tend to have low tear resistance. The SNE-556-R is a 65 durometer conductive silicone used for EMI and environmental sealing. The reinforced fabric is metalized to enhance the Z-axis conductivity of the composite material, which compares favorably with high performance silver filled silicone elastomers. SNE-540-R is a softer version, made in 40 durometer for more conformability. Both SNE-540-R and SNE-556-R are made in 12” and 15” wide continuous rolls, enabling large gaskets to be made without splices. Standard thicknesses are .020” and .032”; custom thicknesses are also available.
