'''Polyether block amide''' or '''PEBA''' is a [[thermoplastic elastomer]] (TPE). It is known under the tradename of PEBAX® ([[Arkema]]) and VESTAMID® E ([[Evonik Industries]]). It is a [[block copolymer]] obtained by [[polycondensation]] of a carboxylic acid [[polyamide]] ([[Nylon 6|PA6]], [[Polyamide 11|PA11]], [[polyamide 12|PA12]]) with an [[alcohol]] termination polyether ([[Polytetramethylene glycol]] PTMG), [[Polyethylene glycol|PEG]]). The general chemical structure is:

Some [[hydrophilic]] grades of PEBA are also used for their [[antistatic]] and antidust properties. Since no chemical additives are required to achieve these properties, products can be recycled at end of life.
