Electrically Conductive Materials

dBseal Gel Rope gaskets Overview

dBseal Gel Rope gaskets provide shielding against high levels of electromagnetic interference (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 dBseal silicone gel material provides an effective barrier against galvanic corrosion. Gel surrounds the conductive wire mesh of the dBseal 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 gel not only minimizes intermetallic corrosion between gasket and substrate, but also ensures dependable EMI shielding and environmental sealing over time.

Standard dBseal gaskets feature wire mesh made of Monel, an alloy of nickel and copper, ideal for its EMI shielding and low cost. Other wire mesh materials are also available.

Application Method
Cold applied without any special surface preparation or adhesive, the gels self-healing characteristic eliminates the need to fuse the ends together to form a gasket
