BASF Ultrafuse TPU 85A
BASF’s First Flexible Filament Based on Elastollan
Ultrafuse TPU 85A has been specially developed for FFF printing and is an advanced filament based on BASF’s Elastollan materials. Elastollan is BASF’s brand for thermoplastic polyurethane (TPU), known for its highest reliability, consistent product quality and cost efficiency.
Ultrafuse TPU 85A offers a wide range of hardness grades with different designs, making it ideal for applications that require specific levels of flexibility. Available in natural white, it has excellent chemical properties and solvent tolerance, useful for specific applications. These characteristics correspond to the data available on polyether-based TPUs. Although not FDA compliant, this material offers good flexibility at low temperatures, very good wear performance and excellent damping behavior.
