STRIPPABLE COMPOSITE OF POLYMERIC MATERIALS FOR USE IN INSULATED ELECTRICAL CONDUCTORS, AND PRODUCTS EOF

摘要

A composite of polymeric materials which are adheringly joined to each other and which can be easily and cleanly separated by stripping apart with a low pulling force whereupon the contacting surfaces of their interface separate cleanly without retention of any residue from the other, and which comprises the combination of a body of ethylene polymer adjoined to a body of an elastomeric blend of polymers comprising ethylene-propylene rubber admixed with a chlorine containing rubber. The combination of materials is especially advantageous when used in wire and cable constructions as a composite of an electrical insulation and an overlying strippable semiconductive layer.
