STRIPPABLE COMPOSITE OF POLYMERIC MATERIALS FOR USE IN INSULATED ELECTRICAL CONDUCTORS, A METHOD OF FORMING THE SAME AND PRODUCTS THEREOF

摘要

ABSTRACT OF THE DISCLOSUREA composite of polymeric materials which areadheringly joined to each other and which can be easily andcleanly separated by stripping apart with a low pulling forcewhereupon the contacting surfaces of their interface separatecleanly without retention of any residue on one from theother, and which comprises the combination of a previously curedbody of a copolymer of ethylene and propylene adjoined to asubsequently cured body of an elastomeric blond of a co-polymer of ethylene and propylene admixed with chlorosulfonatedpolyethylene. The combination of materials is especiallyadvantageous when used in electrically conducting wire andcable constructions as a composite of an electrical insulationand an overlying strippable semiconductive layer.
