<p>PROBLEM TO BE SOLVED: To provide an electrical insulating material having the improved electrical characteristics with keeping the present state that a conventional thermoplastic polyester elastomer has various advantages (heat resistance, flexibility, chemical resistance, and so on), which material is used for the insulator in insulated electrical wires such as internal wirings in electronic equipments and automobiles as well as coated optical fibers and optical fiber cords. SOLUTION: The electrical insulating material is characterized in that the material is formed by blending (A) 100 pts.wt. of a thermoplastic polyester elastomer resin with (B) 1-30 pts.wt. of a rubbery polymer.</p> |
