TPU utstyrsmappe

Thermoplastic Urethane (TPU) is a PVC-free material used in a number of functional areas within Sea to Summit products:

1. As an airproof barrier in our Air-Sprung Cell and Self-Inflating mats. Here it is used in a liquid-extruded format – the TPU bonds to the face fabric for the highest possible level of reliability.
2. As a waterproof barrier in our Accessory Guide Cases and Map Cases; and in several models of our Dry Sacks. Here it is used in a film format, where its superior flexibility (even in cold weather) and waterproofness are key.
3. As a waterproof barrier in the Nylon Folding Bucket. This particular film is also food grade – ideal for water storage.
4. As a transparent window in View Dry Sacks and Travelling Light products – allowing you (and TSA inspectors) to see the contents.

This product has been tested to be waterproof to a water pressure equivalent to a depth of 10 meters, for up to 1 hour when properly closed. The IPX8 rating is not a guarantee that an electronic device stored in the Sea to Summit product will withstand that kind of pressure; nor are these storage products designed for intentional submersion use.

This product is free of any Polyvinyl Chloride (PVC). This means that the production process is significantly more environmentally friendly, and the disposal of the product at the end of its life will also not burden the environment. With advances in modern polymers, it also means there's no reduction in performance.
