Product descriptions

Ultrafuse® TPU 85A offers a wide range of stiffness grades with different designs, making this filament an ideal material for applications where specific degrees of flexibility are critical.

Ultrafuse® TPU 85A is available in its natural white color.

Chemical properties (e.g. resistance to certain substances) and solvent tolerance can be provided if these factors are relevant to the specific application. In general, these properties are consistent with available data for polyether-based TPUs.

This material does not meet FDA requirements.

Good low temperature flexibility, good wear and good damping behaviour are the main characteristics of Ultrafuse® TPU 85A.
