PURPOSE:To provide a foamed fluororesin insulated cable having good appearance, thin coating of 0.2mm oe less, and high foaming ratio. CONSTITUTION:A foamed fluororesin insulated cable is manufactured by extrusion-coating a molten resin composition containing at least fluororesin and a foaming agent on a conductor to form a foamed insulating layer. By using a mixture of 50-90wt% fluororesin (A) having a melt flow rate of 25-30g/10min. and 50-10wt% fluororesin (B) having a melt flow rate of 4-20g/10min. as the fluororesin, a foamed fluororesin insulated cable having good appearance, thin coating, and high foaming ratio can be provided. |
