The only TPE film I could find in Europe.

Product link.

It is a SEBS film made by Dutch company Vreeberg.

Able to seal using PFS-300 impulse heat sealer. Current configuration:

• TIME: 6
• PRESSURE: Snap hit and keep pressure with my forearm, not whole body.

Have tried many glues of all types. including a silicone sealant and Loctite 401 recommended on Henkel's design guide. It could glue to a PU (polyurethane tube, recommended type by Vreeerg), but the glue always disintegrated part of the film which made it weaker eventually under high pressure.

Best solution I found so far is Zip-Ties.
