SSP-2551

SSP-2551 is a 72-durometer nickel-aluminum fluorosilicone tested to MIL-DTL-83528 shielding effectiveness. Resists fuels, solvents, galvanic corrosion

DETAILS

SSP-2551 is a 72-durometer, nickel-aluminum fluorosilicone that’s been tested to MIL-DTL-83528 shielding effectiveness and resists fuels, solvents, and galvanic corrosion. SSP-2551 is ideal for marine environments such as the decks of aircraft carriers, where flange gaskets are subjected to salt spray, jet fuel, de-icing fluids, exhaust fumes, and electromagnetic interference (EMI). 

EMI Shielding with Fuel and Solvent Resistance 

SSP-2551 is filled with nickel-coated aluminum particles that provide effective EMI shielding and electrical conductivity. Compared to other EMI elastomers, nickel-aluminum products deliver the highest shielding effectiveness after long-term age testing. These particle-filled elastomers also have low transfer impedance. They resist fuels and solvents because fluorosilicone is the base material. 

MIL-DTL-83528 and ASTM D991 Testing 

SSP-2551 was tested according to MIL-DTL-83528 shielding effectiveness, a U.S. military specification for electrically-conductive elastomeric shielding gaskets. This SpecShield™ elastomer has a shielding effectiveness of 112 dB at 20 MHz to 10 GHz. Volume resistivity, a measure of an insulating material’s resistance to leakage current through its body, was tested according to ASTM D991 and measured 0.03 ohm / cm.
