Spectrum Filament PEBA
High-Performance Polyether Block Amide | Ultra-Lightweight
Spectrum PEBA is an elite thermoplastic elastomer (TPE) belonging to the Polyether Block Amide family. Known for its legendary use in high-end athletic footwear and aerospace components, PEBA offers a unique combination of Nylon-grade strength and high-performance flexibility.
This material is engineered for applications that demand extreme energy return, low-temperature resilience, and significant weight savings. Unlike standard TPU, PEBA maintains its mechanical properties across a vast temperature range and features a much lower density, allowing for the creation of lightweight, high-speed functional parts.
- Weight: PEBA is ~20% lighter than TPU (Density 1.01 vs 1.21 g/cm³).
- Recovery: Much higher energy return (rebound) with minimal hysteresis loss.
- Cold Resistance: Stays flexible at -40°C where TPU becomes brittle.
- Toughness: Better fatigue resistance for parts undergoing millions of flex cycles.
🏃 Dynamic Energy Rebound
Outstanding elastic recovery makes it ideal for sports equipment and vibration-damping industrial components.
❄️ Extreme Cold Resilience
Maintains consistent flexibility and impact resistance even in Arctic conditions (down to -40°C).
🧪 Industrial Chemical Defense
Excellent resistance to fuels, automotive oils, grease, and a wide variety of industrial chemicals.
📏 Precision Printability
Optimized Shore 90A hardness ensures easier feeding in direct-drive extruders compared to ultra-soft filaments.
- High-performance athletic shoe components
- Ski boot liners and winter sports gear
- Automotive gaskets and flexible ducts
- Vibration isolators and shock absorbers
- Medical device prototypes (non-implantable)
- Aerospace lightweight structural seals

* Expert Tip: PEBA is a high-end technical material. To achieve the best layer adhesion and surface clarity, ensure the filament is perfectly dry. For Bowden extruders, reduce speed to 15mm/s and use a high-quality PTFE tube to minimize friction.
