Material Details

Description

Ultrafuse® TPU 85A offers a broad range of degrees of hardness with different designs, making this filament an ideal material in applications where specific degrees of flexibility are critical.

Ultrafuse® TPU 85A comes in its natural white color. Chemical properties (e.g. resistance against particular substances) and tolerance for solvents can be made available, if these factors are relevant for a specific application. Generally, these properties correspond to publicly available data on polyether based TPUs. This material is not FDA conform. Good flexibility at low temperature, good wear performance and good damping behavior are the key features of Ultrafuse® TPU 85A.

Product properties may be changed without notice. This document does not create any liability, warranty or guarantee of product performance. It is the buyer’s responsibility to determine the suitability of Ultrafuse® products for the intended application.

** To achieve faster printing speeds, it may be necessary to raise the nozzle temperature. The highest speed mentioned has been determined through our latest tests, ensuring optimal surface quality with a 0.4mm nozzle and 0.2mm layer height. Please note that as printing technology and equipment evolve, we anticipate the possibility of achieving even faster speeds in the future.
