High Strength Polyester Resin Prepreg Glass Fiber Banding Tape

Polyester Resin Pre-Impregnated Glass Fiber Banding Tape is manufactured from premium glass fiber non-woven fabric impregnated with thermosetting polyester resin. After heat curing, the tape forms a rigid, high-strength composite structure with excellent mechanical properties, thermal stability, and electrical insulation performance.

• High Mechanical Strength: After curing, the tensile strength can exceed 1000 MPa, providing reliable reinforcement while reducing the number of winding layers required.
• Excellent Heat Resistance: Maintains tensile strength above 700 MPa at 200 °C, ensuring long-term stability in high-temperature operating environments.
• Excellent Electrical Insulation: The non-metallic structure provides insulation properties suitable for motors, transformers, and electrical equipment.

• Motor Rotor End Winding Banding: Used for high-voltage and large industrial motors to secure rotor end windings and improve operational reliability.
• Transformer Core Clamping: Provides non-magnetic mechanical reinforcement for transformer core tie plates and insulation structures.

• Can this tape replace steel wire banding?
  Yes. In many motor and transformer applications, cured prepreg glass fiber banding tape can replace traditional steel wire banding while reducing weight and eliminating eddy current losses.
• Is the tape supplied ready for use?
  Yes. The product is pre-impregnated with thermosetting polyester resin and can be directly wound before heat curing.
