A Very Special Kind of Polymer Chemistry

The secret to the outstanding properties of Pebax® polymers comes from what chemists and materials scientists refer to as "block copolymer technology". Simply put, this enables the polymer designer to use two different chemistries (polyether and polyamide) on the same polymer backbone while retaining the performance properties of both. In other words, each polymer chain contains both polyether "blocks" that enable flexibility and elasticity, and polyamide "blocks" that enable tremendous lightness, strength, and energy return. This essentially enables the polymer to deliver the "best of both worlds" in terms of performance. 

By playing on the ratios of these "blocks" and their respective chain lengths, our chemists can tailor the final polymer to deliver a finely tuned balance of properties depending on the final goal.

A common characteristic of this very special polymer chemistry is what is referred to as a "low energy loss as seen in the hysteresis curve". This essentially means that when the polymer is stretched, it is highly efficient at storing and then returning that same energy when the stress is relaxed. 

Pebax® elastomers are world leading high tech polymers designed for extremely high performance sports wear. They are specified by many of the world's leading brands and relied upon by world record setting athletes. Many publications have referred to this technology as "technological doping" the new "arms race" of high performance sports. Some even describe our polymers as "an unfair advantage".

Pebax Powered® shoes frequently take gold, silver and bronze - just like they did in the Rio De Janeiro marathon.

The Wiley Online Library of Polymer Science says "All available data suggest overwhelmingly that properties of block copolymers are superior to those of random copolymers. A block copolymer can have properties characteristic of each of the homopolymers from which it is derived as well as a set of properties due to the polymer structure as a whole. Block copolymers have an advantage over random copolymers in that a crystalline polymer can be modified without significant reduction of its melting point, modulus, tensile strength, and elastic properties, and by suitable selection of a second component it affords a means of 'building in' a particular property."
