Thermoplastic Urethane thin film
Thermoplastic Urethane thin film
(OP)
I'm electrical seeking advice about materials. I want to use an Ultra Sonic hand held welder to weld TPU on fabric. The welder I'm thinkng of purchasing is 500Watts and operates at 20khz.
I'm not sure what types or grades TPU comes in I just know I need something thin and can be bonded with this hand held welder.
any advicve would be great. I would hate to have TPU can is too thick were it can't be bonded (to fabric that is).
Thanks

Polyurethane is a thermoset plastic, so it doesn't take to welding. However, you can ultrasonic weld a themoplastic to it.

I thought companies that make sports gloves use TPU on the palm portion of the gloves enabling better gripping.
It would be great if the thermoplastic was abrasion resistant. Any suggestions?
Thank you both for your response.

You will not be able to laminate with a welder. You will blow holes in the PU before it sticks properly.
Hot air and roller wheels are used to make things from PU/woven fabric laminates. I have seen divers dry suits made that way.

I respect yours and kenvlach's comments.
Kenvlach can the roller as you mentioned have etches made into them so that I can roll over areas I don't want to have TPU'ed?
For example could I etch a line in the roller and roller over something so I don't heat over the TPU covering that area?
Thanks
