Polyurethane fiberglass insulation sleeve is made of E-glass fiber yarn
and polyurethane resin. Fiberglass yarn is woven finely by high-speed
knitting machines to be blank tube, then it is coated with a specially
formulated polyurethane resin under high temperature curing and then
finally stereotypes. As the work temperature of the sleeve can often
reach 155 degrees Celsius, it has very excellent electrical properties,
and has good mechanical abrasion resistance and flexibility, it is
widely used in F-class motor insulation.
