COVERING MATERIAL FOR MOLDING OF OUTER FACE OF RUBBER HOSE

摘要

PURPOSE:To provide the covering material for molding of an outer face of a rubber hose which has bean stabilized in the quality and improved the produc tivity thereof by a method wherein vulcanizing temperature can be lowered by enhancing the thermal conductivity by comparing with a conventional resin covered material, and the vulcanization time can be shortened. CONSTITUTION:A resin covered material 2 is composed as follows; polymethylphentene ('TPX(R)'; polyolefin having 4-methylpentene-1 as base... manufactured by mitsui Petrochemical Industries, Ltd.) is used as a resin material, and metal powder and granular material 4 of high thermal conductivity such as aluminum. copper, etc., is blended in the polymethylpentene.
