Silicone Rubber Fiberglass sleeving - temperature resistance of - 30 ~ 200 , pressure resistance of 1.2kv-2.5kv (inner fiber and outer glue) - temperature resistance of - 30 ~ 200 , pressure resistance of 4.0kv. The surface of tightly woven glass fiber sleeve is dipped with complete silica gel and cured at high temperature. (outer fiber and inner rubber) - glass fiber sleeve with temperature resistance of - 30 â?? ~ 200 â?? and pressure resistance of 7.0kv woven tightly on the surface of silicone rubber pipe. Srg-n meets the requirements of Part 1 of the Canadian Electrical Code code and the requirements of coated electrical insulating sleeves for higher temperature applications specified by the National Institute of standards and chapter 1.4 of the National Fire Protection Association electrical code. The long-term aging test meets the requirements of ul746b or CSA c22.2 chapter 0.17. It is widely used in internal wiring harness and insulation protection of H & n automobile, shipbuilding, motor, household appliances, electric heating equipment, special lamps, TV and electronic instruments. Srg-w is mainly used in the transportation of high temperature and high pressure fluid and the equipment and instruments that need soft, wear-resistant insulation and mechanical protection.
