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.

Printing with Flexfill PEBA 90A:

• Technical datasheet
• Safety datasheet

• Diameter tolerance: 0.10 mm
• Length: 210 meters (1.75 mm) / 85 meters (2.85 mm)
• * Use a 3D printer with a direct drive extruder
• * Use a 3D printer that is suitable for printing flexible filaments
• * Pre-dry for 5 hours at 70 ° C
• * Use a good bed suture, such as Magigoo PA, 3DLAC or Lockpad
• * Flexfill PEBA absorbs moisture quickly; store in an airless, resealable bag in a dry place

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

Applications:

• 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
