The Kimya PEBA-S 3D filament is a thermoplastic elastomer. Polyether block amide (PEBA) is produced via polycondensation of a carboxylic acid polyamide with an alcohol-terminated polyether. PEBA, based on PEBAX by Arkema, is very flexible: it has the best elongation % in the range (>550%).  It can be used to make shoe soles or other sports equipment (cycling, golf, American football helmet) as it offers substantial energy return. The Kimya PEBA-S  3D filament has the following properties:

Flexibility (>550% tensile elongation at break)
Impact resistance
Complies with the RoHS and REACH standards
