Fiberglass sleeve is mainly divided into two categories, which are inner fiberglass outer silicone resin ( SRG-N) and inner silicone rubber outer fiberglass( SRG-W). SRG-N is made of no-alkali fiberglass yarn woven into the tube, and then coated with silicone resin by high temperature treatment. Because of its flame resistance, wear resistance, tear resistance, flexible, insulation, SRG-N is applied in the areas such as internal wiring of electronics, electrical appliances and automotive, motors, household appliances, etc. SRG-W is extruded into tubes by silicone rubber, which is wrap the woven fiberglass ,and then coated with silicone resin at high temperature. Due to its excellent high temperature-insulation performance, SRG-W is also widely used in electronic appliances, lighting, industrial machinery, heating products and other high temperature place.
