- Commodity name: Polyurethane (PUR) fiberglass casing
Polyurethane fiberglass tubing is made by precisely weaving alkali-free fiberglass yarn into a preform tube using a high-speed weaving machine, then coating it with specially formulated polyurethane resin and curing it at high temperatures to achieve a fixed shape. Because this tubing can withstand temperatures above 155℃ for extended periods, has excellent electrical properties, and shows good mechanical wear resistance and elasticity, it is widely used in F-class motor insulation or vacuum cleaner wire harness wear-resistant sheathing.
Polyurethane fiberglass sleeving is made by precisely weaving alkali-free fiberglass yarn into a preform tube using a high-speed braiding machine, then coating it with specially formulated polyurethane resin and finally curing it at a high temperature. Because this sleeving can withstand temperatures of 155℃ and above for extended periods, and its electrical performance is also excellent, and it also has good mechanical wear resistance and elasticity, it is widely used in F-class motor insulation or vacuum cleaner wiring harness wear-resistant sheathing.
