Polyester Shrinking Tape
Main Parameters:
- Insulation class:F Class (155℃)
- Rolls: 10mm, 15mm, 20mm, 25mm, 30mm, 50mm width
- Thickness:0.23mm,0.26mm,0.29mm
- Can be customized
Polyester shrinking tape is made of a special compound fiber of thermal contraction.after binding and dried at 105℃ for 10 minutes,it will be shrunk to 70%,which is good at a solid binding and at a compatibility with transformers.in this way,it will be utilized in the transformer oil at 105℃ for a long time. Cotton tape made of pure cotton or 60%cotton.glassfiber tape made of glassfiber. Used in transformer and electrical motor.
Polyester Shrinking Tape
- Simple, easy to use heat shrink polyester film tape with a wide range of applications.
- High compressive force ensures effective compression, shaping and consolidation.
- Excellent release characteristics from a wide range of materials.
- Significantly improve the product performance and overall quality level of the transformer.
- High insulation level, good electrical performance; dielectric constant 3, between oil and cardboard, super stable and low loss.
- The heat shrinkage is up to 30%, and the binding is firm and durable, without rebound or slack.
- The tensile strength is high, and the mechanical strength is more than tens of times that of cloth tape.
- Pure chemical substances, no burrs, off-line, markings and other defects on the outside, and no dirt and other substances harmful to electrical insulation.
- It has been approved by UL (NO.: E310670) ,ROHS and REACH test.
