Catheter with body temperature glass transition region

Polymer compositions for molding in the presence of a foaming agent which comprise at least a polyolefin resin as a base resin and low polarity boron compound powder which is not decomposed at a foaming temperature, such as boron nitride powder as a nucleator. Polymer compositions of the invention are useful for formation of a foamed insulating layer on a conductive material by way of foam molding. By using said polymer composition, a foamed insulating layer excellent in insulation properties which has small dielectric loss factor, tan .delta., at high frequency and high extent of foaming of not less than 70% can be obtained.
