What is PEBA 90A Filament?
【Ultra-High Energy Return & Dynamic Cushioning】Engineered with a 70% rebound rate, eSUN PEBA 90A offers superior energy response compared to standard TPU. Its rapid shape recovery and dynamic cushioning makes it the ideal material for printing high-performance insoles, and sports equipment that requires explosive power and shock absorption.
【Lightweight & High Impact Resistance】With a low density of just 1.01 g/cm³, eSUN PEBA 90A is significantly lighter than traditional flexible filaments, ideal for weight-sensitive applications like drones and wearable devices. Exceptional durability with >520% elongation at break and superior impact strength, which ensures parts withstand rigorous use without deformation.
【 Extreme Temperature Stability & Low-Temp Toughness】 eSUN PEBA 90A maintains consistent flexibility and toughness across a wide temperature range. It excels in cold environments, making it perfect for winter sports gear, outdoor industrial parts, and medical protective equipment. Heat deflection temperature reaches up to 110°C (Vicat/10N).
【Optimized Printability for Flexible Parts】 Designed with a Shore 90A hardness, it strikes a balance between flexibility and printability. For best results with hollow models (e.g., tennis balls), use lower bed temps (40-45°C); for solid parts, increase to 60-80°C and use glue to prevent warping.
【Critical Usage Tips (Must Read)】PEBA is highly sensitive to moisture. Drying is MANDATORY before printing (Recommended: 70°C for >5 hours) to prevent stringing and bubbling. Please use a brand new nozzle (avoid nozzles with residual fiber/carbon) and ensure a smooth, low-resistance feeding path (spool holder with bearing is recommended) to ensure consistent extrusion.
