CHO-SEAL 6502 and 6503 EMI gasket materials were developed for high-performance in adverse environments common to aerospace, automotive and telecommunication applications. Are Ni-plated aluminum particle-filled silicone and fluorosilicone elastomers. Offer shielding after exposure to high and low humidity and temperature cycles, as well as salt/fog environments. Come in molded and extruded product forms, as well as a silicone, thermally cured, robotically dispensed and a form-in-place version: CHO-FORM 5560. Filler technology performs when used against aluminum flanges with either MIL-C-5541 trivalent or hexavalent, Class 1A or Class 3 chromate conversion treatment. NiAl particles reduce aluminum flange galvanic corrosion activity by factor of two.
