Siraya Tech Fibreheart PEBA 95A

PEBA Elasticity With a Nylon Backbone

Rebound PEBA 95A is a nylon–elastomer copolymer designed for functional flexible parts. The nylon structure adds durability and chemical resistance, while the elastomer blocks provide smooth flex and fast recovery. This gives printed parts a firmer, more “responsive” feel than standard TPU.

High Rebound for Dynamic Parts

With up to 78% energy return, parts bounce back quickly after deformation. This makes the filament a strong choice for applications where movement, impact absorption, and repeated flexing are important, such as sports gear, wearable components, and robotics.

Lighter Than TPU 95A

Rebound PEBA 95A can produce parts that are roughly 15–20% lighter than typical TPU 95A prints. That’s useful in weight-sensitive designs like drones, athletic equipment, or moving mechanisms where every gram matters.

Chemical Resistance That Expands Use Cases

The material shows excellent resistance to oils, greases, fuels, and many industrial solvents. This helps parts keep their elasticity and surface quality in harsher environments compared to many TPU-based alternatives.

Printing Tips

PEBA benefits from dry storage. Dry the filament before printing when possible and keep it sealed between uses. Use a direct-drive extruder for best control, moderate speeds, and ensure consistent cooling to maintain smooth surfaces and reliable layer bonding.
