BASF Natural Ultrafuse TPU 85A Filament 1.75mm, 0.75 kg

The BASF Ultrafuse TPU 85A is a thermoplastic polyurethane filament based on BASF Elastollan material and optimized for FFF 3D printing. The material features characteristics of both thermoplastics and rubbers, combining durability and extreme flexibility.

Exceptional elasticity alongside wear and abrasion resistance, high tensile strength, and resistance to chemicals make the Ultrafuse TPU 85A suitable for a bunch of applications. It is widely used in automotive industry for interior elements manufacturing, in agriculture, and construction. Due to its flexibility and excellent damping properties, the TPU 85A is an ideal solution for sportswear and athletic shoes fabrication. The BASF Ultrafuse TPU 85A comes in its natural white color.
