Abstract:
An electrical wire or cable having insulation comprising(I) a first layer which is composed of a first polymeric composition consisting of a first polymeric component and optionally a first non-polymeric component, the first polymeric component comprising at least 20% by weight, based on the weight of the first polymeric component, of a carbonyl-containing polymer comprising at least 5% by weight, based on the weight of the carbonyl-containing polymer, of repeating units derived from a monomer which can be copolymerized with an olefinic monomer and which contains a carboxylic acid ester group; and (II) a second layer which is in direct contact with the first layer at an interface, and which is composed of a second polymeric composition consisting of a second polymeric component and optionally a second non-polymeric component, the second polymeric component comprising at least 10% by weight, based on the weight of second polymeric composition, of a fluoropolymer, and being free of polymers containing more than 50% by weight, based on the weight of the polymer, of repeating units derived from vinylidene fluoride.
