We supply conductive silicone elastomers used to produce shielding gaskets for military, aerospace, electronics, automotive, medical and telecom applications. Available as conductive sheet stock or ready-to-mould compound.
Queensland Gasket’ is the sole Australian supplier of Specialty Silicone Products (SSP) EMI RFI conductive silicone rubber materials. Designed by SSP in New York, these materials were produced in direct response to customer problems typically faced with metal-filled elastomers.
SSP’s EMI RFI silicones conduct electricity, resist electromagnetic interference (EMI), and provide environmental sealing. Silicone or fluorosilicone is the base material that is filled with metal or metal-coated particles. Silicones can withstand water, ozone, ultraviolet light (UV), and a wide range of temperatures. Fluorosilicones add fuel and solvent resistance.
To provide EMI RFI shielding and electrical conductivity, SSP fills the base elastomer (a natural insulator) with silver, silver-aluminum, silver-copper, silver-glass, or nickel-glass particles. These fillers differ in terms of cost, conductivity, and maximum volume resistivity (VR) – an indirect measure of shielding effectiveness. They also differ in terms of minimum shielding performance according to MIL-STD-83528.
Balancing cost and performance is important, but many electronic designs need to meet application-specific requirements. That’s why SSP’s EMI RFI silicones include compounds that are softer and thinner, that reduce tearing, resist galvanic corrosion, or meet tough standards.
Specialty Silicone Products manufactures EMI RFI silicones at its Ballston Spa, New York (USA) facility and serves customers worldwide. Our elastomers support gasket fabrication through a variety of methods and can strengthen your supply chain along with your electronic designs.
