TPU 85A

BEDROCK 3D TPU 85A delivers a high degree of flexibility, a broad range of degrees of hardness in different designs, without compromising on strength or durability. It’s ideal for functional parts in footwear, sports, and leisure, as well as industrial, automotive, agricultural, and construction applications. Whether you need flexible components that absorb impact or durable parts that handle mechanical stress, TPU 85A provides consistent, reliable performance. Trouble free printing due to high diameter consistency.

It 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.
