Red Vulcanized Fiber is made of cotton pulp, wood pulp and zinc oxide. It is conglutinated by the cementing compound under thermophilic temperature. With a hand feature and good elasticity, it shows excellent abrasive resistance, heat resistance, mechanical strength and electric strength
Thermal class: F
Application:
it is widely used in slot, phase and liner insulating of motor, transformer and so on.
