Conductive elastomers are for RFI/EMI shielding
Conductive elastomers are manufactured as gaskets and gasket strip for EMI shielding of electronic devices by Kemtron. The base elastomer is silicone for normal environments and fluorosilicone for fuel and oil resistance. Both offer a wide temperature range of -40 to +160° and +200° for some grades. The conductive fillers available are silver-plated aluminium, silver plated copper, pure nickel and nickel-coated graphite.
The company produces a flame retardant version of nickel graphite in silicone, tested and approved to the international standard UL94V-0 for flame retardancy.
The process capability is extrusion, moulding and conductive vulcanised jointing. Many extrusion profiles are available including cords, tubes, hollow D, solid D. with custom profiles available. Extrusions are supplied in continuous lengths, cut to length or made into large or small diameter O rings which are produced by joining extruded profiles with the same conductive compound as the base material. The joint is heat vulcanised ensuring a strong conductive joint. Mouldings include sheet stock, O rings, custom shapes and gaskets. Sheets can be die-cut to customers’ design and a conductive PSA can be applied to aid assembly.
The company also deposits liquid conductive silicones directly to customers’ hardware as a form-in-place gasket. This process can deposit very small (0.4 high X 0.5 wide) gaskets on complex paths with narrow land.
The company also manufactures shielding gaskets and components providing a comprehensive EMI shielding service to the electronics and enclosure industry.
