Polyethylene, polypropylene, and neoprene are commonly used insulating materials on wire and cable for underwater service, as are stainless steel and beryllium copper for connector hardware. Ethylene Propylene Diene Rubber EPDM, a synthetic rubber having chemical building blocks in common with polyethylene and polypropylene and physical properties similar to neoprene, has been investigated as a potential tie material between these insulations. An EPDM FORMULATION HAS BEEN DEVELOPED, UTILIZING A PEROXIDE CURE SYSTEM THAT WILL DEVELOP SATISFACTORY PHYSICAL PROPERTIES OVER A CURE TEMPERATURE RANGE COMPATIBLE WITH POLYETHYLENE, POLYPROPYLENE, AND NEOPRENE. This formulation has been molded and cured against samples of these materials as well as stainless steel, and beryllium copper, with various surface treatments, and the adhesion bonding obtained measured quantitatively. Test results indicate that, dependent on surface treatment and cure parameters, a reasonable degree of bonding can be achieved between the EPDM formulation and each of the other materials.
