Shock Resistance & Durability

Low temperature impact performance is essential for manufacturing a durable ski boot. Pebax® elastomers and Rilsan® PA11 have exceptional cold impact performance making them durable solutions for ski boots. Rilsan® polyamides also have excellent scratch and UV resistance, making them a great solution for protective ski top layers.


Flexibility & Comfort

Boots can be a skiers best friend or worst enemy. Crafting a boot that maintains flexibility and comfort even at extremely low temperatures can make a huge difference for skiers. Pebax® elastomers outperform TPU, COPE, and other alternatives when it comes to cold stiffening, which makes for a more resilient and comfortable ski boot. Rilsan®polyamide ski top layers also maintain flexibility at low temperature and have the process flexibility to make sublimation printing (and other decoration technology) hassle-free.



The shear amount of plastic used in ski boots today only magnifies the importance of choosing a lightweight polymer when designing high-end equipment. Both Pebax® elastomers and Rilsan®polyamides have lower densities (up to 20%) than TPU and COPE alternatives. This is especially important for touring (freeride) boots where the ski trip often involves a long hike. 


Ski Boot Solutions


Pebax® elastomers are the material of choice by some of the most recognized ski boot manufacturers. The Pebax® family consists of grades with varying flexibility and hardness levels, and the option of being partially biobased (Pebax® Rnew® range).  The wide range allows for exceptional solutions for alpine, cross-country, and touring (freeride) skiing styles.

Suggested grades to start your development:

  • Pebax® 7033 SP 01(Datasheet US/SI)
  • Pebax® Rnew® 70R53 SP 01(partially biobased) (Datasheet US/SI)
  • Pebax® 7233 SP01 SP 01(more rigid) (Datasheet US/SI)
  • Pebax® Rnew® 72R53 SP 01 (more rigid, partially biobased) (Datasheet US/SI)
  • Pebax® Rnew® 80R53 SP 01 (very rigid, partially biobased) (Datasheet US/SI)
  • More rigid and lighter grades are also available

Ski Top Layer Solutions


Rilsan® PA11 and Rilsamid® PA12 are both excellent choices for use as protective ski top layers, which is why these resins have been used for over 20 years. Both of these resins process into films easily and make for simple sublimation printing.  A high level of transparency also makes for beautiful finished graphics. Rilsan® PA11 exhibits improved scratch resistance and mechanical properties compared to PA12, so for high-end models, manufacturers should opt for PA11. Rilsan® PA11 also has the benefit of being biobased, with 100% of its carbon content originating from the castor plant.

Suggested grades to start your development:

  • Rilsan® BESNO TL (biobased) (Datasheet US/SI)
  • Rilsan® BESNO 23 TL4CC  (biobased) (Datasheet US/SI)
  • Rilsamid® AESNO 14TL(Datasheet US/SI)
