It is produced according to the requirements of GB/T75 9 4.7-8 7 and meets the requirements of the coal industry standard MT8 18-2009.
It is used for heavy-duty cable jackets with long-term allowable operating temperature of 65 °C. It has high strength. It is oil-resistant, heat-resistant, ozone-resistant and flame-retardant. The cable is especially suitable for long-term use in harsh working environments, and can completely replace the neoprene (C R) compound. The performance of the red and yellow cable sheathing materials produced by the company meets the requirements of GB 1 29 7 2-9 1 standard.
