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.\n\nPrinting Recommendations:\nUltrafuse TPU can be printed directly onto a clean build plate.
