ABSTRACT:
Electrically insulated wire with an inner layer of non-crosslinked and non-crosslinkable polymeric material and a skin layer of irradiation crosslinked material compatible with the inner layer. The inner layer provides desirable flexibility and electrical insulating properties suitable for telecommunications cable and appliance wiring. The skin layer gives abrasion resistance suitable for the above purpose and heat resistance and fire retardance properties suitable for building wiring. The polymeric material of both layers is preferably of a polyvinylchloride composition.
