Ultrafuse TPU 85A
Date / Revised: 06.11.2020

Version No.: 2.4

General informationComponents
BASF thermoplastic polyurethane (TPU) based filament for Fused Filament Fabrication.

Product Description
Ultrafuse TPU 85A comes in its natural white color. Chemical properties (e.g. resistance against particularsubstances) and tolerance for solvents can be made available, if these factors are relevant for a specificapplication. 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.

Delivery form and warehousing
Ultrafuse TPU 85A filament should be stored at 15 - 25°C in its originally sealed package in a clean and dryenvironment. If the recommended storage conditions are observed the products will have a minimum shelf lifeof 12 months.

Product safety
Please process materials in a well ventilated room, or use professional air extraction systems. For further andmore detailed information please consult the corresponding material safety data sheets.
