  • About Seamax Air Chamber Seams

    When we talking about the latest air chamber seam standard, Hot (Air) Welded and Thermo Bonded are belong to the same type of seam processing. The main chamber seam staying together is not longer using the PVC glue. So the air chamber seam won’t be damaged when time being or daily use, Since the PVC glue life time is 3-10 years based on workmanship and condition of use. Hot welded (or Thermo welded) seam may reduce over 50% of boat major repair service and be able to extend the boat life time to be over 10-15 years.

    Seamax has been making our Ocean Series and Ocean T Series inflatable boat with hot welded seam since 2017. And we use the over-lapped major seam structure let the chamber fabric staying together by themselves and not using an additional seam tape. Seamax still use seam tape as add-on with best result. It seems like we give the boat an extra welded seam, and we call it Double Hot Welded.

    The PVC boat industry standard is joined chamber seam, I believe it should give a higher chance of air leaking after finished. Usually the same style over-lapped major seam structure can be found from high-end Hypalon boats. Boat using over-lapped seam will use more material to build and many extra hours. At the mean time it requires better skill worker to make it right. Now we can be confident to tell that our chamber seam’s life time will be as the same as the fabric’s life time. In the other word, when the day the boat life time ended, it should not be from the chamber seam issue.

    Right now, all our Seamax boats manufacturing are the same. Hot welded seam for PVC boat brings the boat overall quality much closer to Hypalon boat. And Seamax boat with German PVC to build can bring Seamax with a highest standard in the inflatable boat industry.
