<h2 id="applications">Applications</h2>
<p>PEBA is found in the <a href="/facts/Sports_equipment/FqBaqLdn">sports equipment</a> market: for <a href="/facts/Damping_ratio/UW3RsjEd">damping</a> system components and midsoles 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 participants as it enables design of the lightest alpine and Nordic <a href="/facts/Ski_boot/LRW0N6tf">ski boots</a> while providing some resistance to extreme environment (low temperatures, <a href="/facts/Ultraviolet/kncBUqn5">UV</a> exposure, moisture). It is used in various other sports applications such as racquet grommets and golf balls.
</p><p>PEBA is used in medical products such as <a href="/facts/Catheter/ehnH1eF5">catheters</a> for its flexibility, its good mechanical properties at low and high temperatures, and its softness.
</p><p>It is also widely used in the manufacture of electric and electronic goods such as cables and wire coatings, electronic device casings, components, etc.
</p><p>PEBA can be used to make <a href="/facts/Textiles/PJrVeM5S">textiles</a> as well as breathable film, fresh feeling fibres or <a href="/facts/Nonwovens/XeFJRS0B">non-woven</a> fabrics.
</p><p>Some <a href="/facts/Hydrophilic/k8p95WYu">hydrophilic</a> grades of PEBA are also used for their <a href="/facts/Antistatic/LLQ1lpDz">antistatic</a> and antidust properties. Since no chemical additives are required to achieve these properties, products can be recycled at end of life.
