Line 1: {{Short description\|Thermoplastic elastomer}} {{one source\|date=July 2020}} '''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 (chemistry)\|alcohol]] termination polyether ([[Polytetramethylene glycol]] 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]])<sub>n</sub> - [[Hydrogen\|H]] Line 66 ⟶ 67: \|- \| Surface resistivity \| Ω/sq \| 10<sup>9</sup>–10<sup>13</sup> \|- Line 81 ⟶ 82: [[Category:Copolymers]] [[Category:Polymers]] [[Category:Thermoplastic elastomers]]
