Abstract
PURPOSE:To eliminate foaming at the time of extrusion work and improve the mechanical strength by letting calcium carbonate surface-procesed with fatty acid surface active agent included in specified polymer, and bridging same. CONSTITUTION:Composite material is obtained by adding calcium carbonate surface-processed with fatty acid surface active agent by 5-100wt.% and bridging agent by more than 0.5wt.% to ethylenefluorolefin copolymer to 100wt.% polymer consisting of tetrafluoroethylenepropylene copolymer grafted by 5-60% for at least one of styrene or acrylic ester. This composite material is coated around a conductor, and this coating layer is bridged by radiation of radial rays. Foaming at the time of extrusion work can thus be eliminated, and the mechanical strength can be improved.
