Sleevings & Binding Tapes
Polyester Heat-Shrinking Tape
Shrinks after 105°C treatment for tight coil binding
Polyester heat-shrinking tape made from a special compound fiber of thermal contraction. After binding and drying at 105°C it shrinks, giving solid binding and a good compatibility with transformer oil.

Values are typical values or ranges from our product data. Bulk supply is subject to the approved specification, sample and test report. If a parameter you need is not listed here, ask our engineers for the full test report for that grade.
Key features
- Shrinks on heating for tight binding and reduced coil loosening.
- Compatible with transformer oil for oil-immersed coils.
- High strength and dielectric withstand for combined binding and insulation.
Applications
Coil binding in motors, transformers and auxiliary appliances; coil tightening in oil-immersed transformers.
Electric Motors & GeneratorsOil-Immersed Transformers
Why it fits
The binding tightens itself during the drying cycle - coils go into the tank locked, not loose.
