が少なく、がっ、高価であり実用上不利である。(Conventional technology and problems) As shown in the drawing, conventional silicone rubber cord heaters have a structure with a silicone rubber layer made by spirally winding a metal resistance wire 2 around a glass fiber string 1 and an insulating layer 3. Because of its good electrical properties, heat resistance, and cold resistance, it is often used in compressor crank cases of refrigeration equipment, pipelines, etc. However, silicone rubber has insufficient resistance to certain oils and solvents, which limits its use in areas where it may come into contact with, for example, gasoline or hydrocarbon solvents. Until now, fluororesin cord heaters have been mainly used in places where oil resistance, solvent resistance, and heat resistance are required, but they are less flexible, expensive, and disadvantageous in practice. .

徴が失われてしまうと同時に高価となってしよう。(Structure and operation of the invention) That is, the cord-shaped heater of the present invention has a composition in which silicone rubber and fluororubber are mixed in a range of 80:20 to 30:70 (weight ratio), which is formed as an insulating layer or an exterior, and cross-linked. It is what was done. This composition improves the oil resistance while maintaining the heat resistance and cold resistance of silicone rubber, and when the amount of fluororubber used is small, the oil resistance and solvent resistance are low (the conventional problem cannot be solved). Furthermore, if too much fluororubber is used, the cold resistance will be greatly reduced, the characteristics of silicone rubber will be lost, and at the same time it will become expensive.
