SynWrap – Wrapping Tapes Polyester shrinkage tape
Polyester shrinkage tape is made of 100 % endless, colourless polyester silk wound with solid edges.
The inelastic, textile tape is additionally characterised by its high mechanical strength and abrasion resistance even at higher temperatures. Use in class F systems when combined with suitable resins is therefore possible.
Application
The polyester shrinkage tape is often used for fixing or bandaging the winding heads of electric machines, since the tape shrinkage additionally increases the packing density of the winding during hardening.
Furthermore, it is used to fix windings, coils and rods in electric machines and transformers. It is occasionally used as filling material, for example in cables.
