Heat Shrink Tape (Polyester Fiber Woven Tape)

Product Description:

Heat Shrink Tape (Polyester Fiber Woven Tape)

Heat shrink tape is woven from high-shrink polyester fibers and offers excellent chemical resistance and insulation properties.

It is widely used for binding transformers, motors, and electrical equipment.

Product Features:

1. Simple process; can replace traditional white yarn tape.

2. Tight coil binding without additional painting.

3. High shrinkage rate and hot tensile strength, preventing loosening or falling off.

4. Does not pollute transformer oil, maintaining equipment cleanliness.

Product Applications:

Suitable for binding and covering coils, heads, transposition parts, and lead enclosures in transformers, mutual inductors,

and motors during manufacturing.
