Longkou Baoshi Insulation Material Technology Company

Polyurethane glass fiber sleeves are made by finely knitting alkali-free glass fiber yarn into a tube using a high-speed weaving machine, then coating it with specially formulated polyurethane resin, followed by high-temperature vulcanization and shaping. Because this sleeve can withstand temperatures above 155°C over a long period, has excellent electrical performance, and has excellent mechanical wear resistance and elasticity, it is widely used in Class F motor insulation or vacuum cleaner wiring harness wear-resistant sheaths.
