Flexfill PEBA 90A is a flexible filament resistant to extremely low temperatures and chemicals.
Flexfill PEBA 90A is made from Polyether-block-amide; the polyamide share provides good chemical resistance.
PEBA differs from TPU and TPE in that it is stronger and more flexible and has a much better chemical resistance. Furthermore, PEBA is still flexible at lower temperatures down to -60 ° C. PEBA absorbs vibrations and impacts better than TPU / TPE.

Advantages of PEBA over TPU / TPE:
- Higher impact resistance (higher energy return)
- Much better chemical resistance
- Flexibility at very low temperatures down to -60 ° C
- Resistant to deformation
- Lowest density of all Flexfill filaments
- Better resistant to wear
- Better absorption of vibrations
- Recyclable, BPA free, hardly fumes
- Flexfill PEBA can be used for printing:
- Automotive: containers for liquids, oils and fuels
- Shoe soles due to the abrasion resistance, resilience (= energy return) and low density.
- Parts for your ski boots due to the temperature resistance at low temperatures
- Electronic devices
- Machine parts that have to absorb vibrations and cyclical forces
