Hi,

I have a question regarding the 450GSM material: Regardless of technique/temp etc the TPU on the 450GSM lifts off when I am doing a “pull apart test”. I have included a picture to help show my meaning. When there is a long run pulling left/ right away from the other yellow the bond is really very strong but as soon as I pulled from the bottom upwards it failed “relatively” easily – easier than the bonds created by the standard materials.

Am I doing something wrong? Is that expected?

I think I’ve got a good technique for the standard materials which are bonding well and very strong. I am using the same temp iron although I have experimented hotter/colder. I am ironing the standard (Yellow) onto the 450. Happy to provide a video if that helps.

Cheers

Jason

Hey Guys and Gals

Received my 2 Twelka kits (red and yellow) packrafts. Just practicing welding. So far so good but only time will tell.
