Silicone glass fiber sleeve is made of non alkali glass fiber yarn woveninto a pipe and coated with silicone resin for high temperature treatment. The silicone glass fiber sleeving produced by our company is made of alkali-free glass fiber yarn woven into a tube, which is then coated with silicone and heat-treated.
The main features aregood dielectric, self extinguishing and flexibility, it is widely usedfor insulation protection ofH & n class motors, household appliances, electric heating equipment, special lamps, TV and electronic instruments.
Appearance: silicone coated fiberglass sleeve surface is smooth, the thickness is uniform, and the silicone resin coating film is coated
Continuoususe temperature: -40℃~200℃--UL standard test
Flammability: VW-1--ul1441 test
Temperature resistance: 265 + 2 ℃ 168h ≥ 1/2 original voltage value - Ul standard test
