Fiberglass Tape is weaved with glass fiber. Glass fiber has good insulativity and heat resistance. It is divided into two kinds----no-soda glass fiber and medium-soda glass fiber. The no-soda glass fiber has much better insulativity. It is widely used in construction, waterproof, anticorrosive, and coil's insulation packing of electrical machinery and apparatus. It is the ideal substitution for asbestos tape.
