'''Polyether block amide''' or '''PEBA''' is a [[Elastomer|thermoplastic elastomer]] (TPE). It is also known under the tradename of PEBAX®. It is a [[ block copolymer]] obtained by [[polycondensation]] of a carboxylic acid [[polyamide]] ([[Nylon 6|PA6]], [[PA11]], [[PA12]]) with an [[alcohol]] termination polyether ([[PTMG]], [[Polyethylene glycol|PEG]]). The general chemical structure is:

:[[Hydrogen|H]][[Oxygen|O]] - ([[Carbon|C]][[Oxygen|O]] - '''[[Polyamide|PA]]''' - [[Carbon|C]][[Oxygen|O]] - [[Oxygen|O]] - '''[[Polyether|PE]]''' - [[Oxygen|O]])_n - [[Hydrogen|H]]

==Applications==

PEBA is found in the [[sports equipment]] market: for [[damping]] system components and outsoles of high end shoes (running, track & field, football, baseball, basketball, trekking, etc.) where it is appreciated for its low density, damping properties, energy return and flexibility. PEBA is also appreciated by winter sports amateur as it enables design of lightest alpine and nordicNordic [[ski boot]]s while providing some resistance to extreme environment (low temperatures, [[UV]] exposure, moisture). It is used in various other sports applications such as racquet grommet sand golf balls.

PEBA is used in medical products such as [[catheter]]s for its flexibility, its good mechanical properties at low and high temperatures, and its softness.
