Chomerics has introduced a new line of EMI gasket materials, developed specifically for high performance in adverse environments common to aerospace, automotive and telecommunication applications. CHO-SEAL 6502 and 6503, nickel-plated aluminum particle (Ni/Al) filled silicone and fluorosilicone elastomers offer initial and long-term shielding effectiveness after exposure to both high and low humidity and temperature cycles, as well as salt/fog environments. The gaskets are available in molded and extruded product forms as well as a silicone, thermally cured, robotically dispensed and a form-in-place version, CHO-FORM 5560. This new filler technology performs especially well when used against aluminum flanges with either MIL-C-5541 trivalent or hexavalent, Class 1A or Class 3 chromate conversion treatment. The Ni/Al particles reduce the aluminum flange galvanic corrosion activity by a factor of two. Read more from Chomerics.
