    hello,
    i would try to work with extremtextil fabric.
    i will test two mini irons. one with 20w and the other is matts standard iron.
    with which temperature you weld the extremtextil fabric?

    i ask myself if it’s a good idea to use double coated 210d fabric from extremtextil with stripes over the seals.

    regards mike

    • Hi, sorry for the late delay.
      I used my heat sealing iron, coverite iron on max temp, aprox 400-420 f-220 d.celsius. Any other heat sealing iron will problably NOT work. The Coverite is a 150 w iron, have tried with a modified 60 w iron and it did not put out the heat needed. I have a modified soldering iron 60 w with a iron tip that work superb on Matt`s fabric on max heat settings. But for fabric from extremetextil, coverite or any similar heat selling iron is the answer to get propper welding.
      Actually I think the best fabric from extremtextil to build packraft from would be the 500 D Cordura TPU, have tried welding on test fabric and it is as hard to weld as 210 D from extremetextil but the fabric is much stronger, way over the 210 Denier TPU fabric. I would try to build a packraft during wintertime as coming in Norway as we speak with this fabric.
      Good luck building and don´t hesitate to contact me if you have more questions.
      Last: I would recommend to not use 210 D tpu singel or dobbel side tpu for floor, but 420 D tpu if you go forward with you’re build. Extremetextil have 420 D singelside tpu.

      Best Regard Kjetil
