BASF – Ultrafuse TPU 85A – Natural White M. Holland

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.
