eSun PEBA-90A Filament

The PEBA 90A 3D printing filaments feature ultra-high resilience, light weight, excellent impact resistance, and stable performance across a wide temperature range. They are ideal for high-toughness, high-elasticity applications such as sports equipment, medical braces, and flexible industrial components.

PEBA-90A offers strong dynamic cushioning and rapid deformation recovery, effectively absorbing impacts while delivering significant energy return upon release. It is particularly suitable for applications requiring shock absorption, cushioning, and propulsion.

In sample testing, when steel balls of the same size were dropped from the same height, the rebound height of the PEBA sample ball was significantly higher than that of the TPU sample ball.

Ultra-Lightweight, Lighter than TPU
Density as low as 1.01 g/cm³
15–20% lower density than TPU

With a density below 1.05 g/cm³, PEBA is 15–20% lighter than TPU, significantly reducing component weight while maintaining strength, empowering lightweight design.

Smoother Printing, More Stable Performance
Printing speed 300% faster than TPU
Maximum volumetric flow 9 mm³/s

PEBA generally requires lower printing temperatures and has a lower shrinkage rate, reducing the risk of warping. At the same hardness, its printing speed is over three times faster than TPU.

Excellent Flexibility and Bend Resistance
Durable and Wear-Resistant

PEBA demonstrates outstanding fatigue resistance, withstanding pressure and repeated bending without permanent deformation or performance degradation.

No Low-Temperature Brittleness
Consistently Excellent Toughness
Operating temperature range: -40°C to 90°C

Whether under normal, low, or high temperatures, PEBA maintains excellent flexibility, elasticity, and impact resistance, making it especially suitable for cold environments or low-temperature applications.
