eSun PEBA-90A

1.75mm 800g

eSUN PEBA 90A is a high-performance flexible filament developed for applications requiring durability, elasticity, and light weight. The material is based on polyether block amide (PEBA) and combines the strength of polyamide with the flexibility of elastomers. The result is a filament with excellent rebound, impact resistance, and long-lasting flexibility.

Compared to traditional flexible materials like TPU, PEBA 90A offers lower density, higher print speed, and better resilience. This makes it an obvious choice for functional parts that need to withstand repeated bending, impact, and demanding environments.

Key features

• Shore hardness 90A with rubber-like flexibility
• Lightweight material with lower density than TPU
• Excellent rebound and shock absorption
• High resistance to wear, fatigue, and repeated bending
• Retains flexibility over a wide temperature range
• Ideal for functional, flexible, and shock-absorbing parts

High-performance flexible material

PEBA (polyether block amide) is an advanced thermoplastic elastomer that combines rigid polyamide segments with flexible polyether components. This unique structure gives the material an excellent balance of strength, flexibility, and durability. Parts printed with PEBA 90A can be stretched, bent, and absorb impact while retaining their original shape.

Lightweight material with excellent rebound

One of the most significant characteristics of PEBA 90A is its high resilience and energy return. Printed parts quickly return to their original shape after deformation, making the material ideal for components that require damping, vibration reduction, or shock absorption. At the same time, its density is significantly lower than many flexible filaments, which helps reduce the weight of printed parts without compromising performance.

Developed for functional applications

Thanks to its durability and flexibility, PEBA 90A is suitable for a wide range of practical applications. The material performs particularly well in products that require both elasticity and mechanical strength, such as protective components, wearables, and industrial parts. The material also maintains stable performance over a wide temperature range and remains flexible even in colder environments.

Typical applications include:

• Sports and protective equipment
• Flexible industrial components
• Medical support products and wearables
• Shock-absorbing parts and vibration dampeners
• Lightweight functional prototypes

With its combination of elasticity, resilience, and durability, eSUN PEBA 90A is a versatile filament for both makers and professional users who want to produce strong yet flexible parts.
