Polyurethane (PUR) fiberglass casing

Polyurethane fiberglass sleeves are made by high-speed weaving machines precisely weaving alkali-free fiberglass yarns into preforms, then coating them with specially formulated polyurethane resin, and finally shaping them through high-temperature vulcanization. Because these sleeves can withstand temperatures of over 155℃ for extended periods, have excellent electrical properties, and exhibit good mechanical abrasion resistance and elasticity, they are widely used in F-class motor insulation or as abrasion-resistant sheaths for vacuum cleaner wiring harnesses.

    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 finally curing it at a high temperature. Because this tubing can withstand temperatures of 155℃ and above for extended periods, and also possesses superior electrical properties, good mechanical wear resistance and elasticity, it is widely used in F-class motor insulation or as a wear-resistant sheath for vacuum cleaner wiring harnesses.
