Specialty Silicone Products SSP-502-65-032-Composite - NG-1


SSP-502-65-032-Composite - NG-1

Typically, in order to manufacture a highly conductive silicone elastomer, it must be filled with a very high loading level of conductive fillers, such as nickel coated graphite. In many other shielding products, the increased conductive filler loading results in a decrease of the rubber and sealing properties of the final product, in regards to tear, compression and other overall physical properties. SSP-502-65-032-Composite-NG-1 counteracts this by utilizing a nickel coated conductive fabric that increases the product’s physical properties exponentially in both strength and conductivity (shielding effectiveness).

Most EMI/RFI silicone gaskets are very expensive and standard non-reinforced materials are subject to being torn or damaged in production, installation, or in use.  Additionally, a more important factor than even the cost of the material, is the risk of potential failure of high end electronics due to material breakdown.  If an EMI/RFI gasket tears while in use, the risk of Electromagnetic Interference due to shielding loss is greatly increased. By reinforcing the silicone used in SSP-502-65-032-Composite-NG-1, the chance of tearing is significantly reduced versus more brittle non-reinforced EMI/RFI silicone gaskets.

SSP-502-65-032-Composite-NG-1 can be manufactured in a continuous roll, allowing for fabrication of larger non-bonded gaskets than can be made out of sheet molds that limit the size of the fabricated gaskets.
