Electrically Conductive Materials

Dow Corning® Brand Electrically Conductive Materials
     

1) Dow Corning® Geltek Rope Gaskets:
• provide shielding against high levels of EMI
• environmental and pressure sealing against water ingress and electrical grounding in a variety of electronics and communications applications.

Extensive salt fog tests have shown that the Dow Corning silicone gel material provides an effective barrier against galvanic corrosion. Gel surrounds the conductive wire mesh of the gaskets and isolates the metal substrate-to gasket contact points from corrosive elements. The unique wire mesh/silicone gel construction also ensures that the electrical resistance of the wire mesh will not increase significantly due to corrosion. The surface wetting action of the geltek not only minimizes intermetallic corrosion between gasket and substrate, but also ensures dependable EMI shielding and environmental sealing over time. Standard Dow Corning geltek gaskets feature wire mesh made of Monel®, ideal for its EMI shielding and low cost.

EMI-CSI-M3 EMI
• Gel Rope Geltek Gaskets Commercial-grade, precured silicone gel with Monel circular knit rope

2) Dow Corning® Geltek Shielding Gaskets:
Dow Corning shielding gaskets provide shielding and effective grounding of high energy EMI. Extensive
laboratory testing in salt fog and fluid resistance has shown that Dow Corning gel gaskets provide an effective barrier against corrosion. This patented product made of soft silicone or fluorosilicone gel material conforms to irregular surfaces to protect them from corrosive elements, and provide corrosion protection.
