* Restrictions apply, a copy of all certifications can be downloaded, or will be sent to you upon request. We will be happy to advise further if you have any questions.

Production Methods used

Joining / Bonding:

• Welding
  • HF high frequency welding
    Welding the material and cooling it down under compression with Radio Frequency to make the TPU material flow nearly seamless to form a uniform thickness with the original material wall thickness.
  • Heat contact – with silver alloy heating element
    Welds are welded surface to surface after which the weld are compressed while cooling.
  • Hot air – hot filtered and conditioned contaminent-, oil- and greas- free compressed air

Cutting:

• Stainless Steel knives
• Water Jet cutting
