Abstract
PURPOSE:To realize wire coating without a danger of foaming at the time of extruding, by adding a predetermined quantity of calcium carbonate, to which the predetermined treatment is performed, to the insulating material mainly composed of tetrafluoroethylene to bridge with radioactive ray. CONSTITUTION:The insulating coating material is mainly composed of copolymer of tetrafluoroethylene and alpha-olefine of which number of carbon is 2-4 and the resinous composition including the polymer of ethylene - tetrafluoroethylene - fluoroolefine, and a predetermined quantity of the additive is added to 100 weight part thereof to be bridge with radioactive ray. For the additives, calcium carbonate 5-100 weight part and bridging assistant 0.5 weight part of which surface is treated with fatty acid group surface active agent are used. For additional additives, calcium carbonate 5-100 weight part and silica 2-50 weight part and bridging assistant 0.5 weight part can be used.
