A very soft TPU for highly compliant parts where flexibility is the primary requirement.

CommodityStocked
What it’s for
Gaskets and seals, Cable management, Functional prototypes. We choose the final route against the geometry and service environment, not from the material name alone.
Key characteristics
- 01Its low-durometer elastomer composition deforms readily.
- 02That makes parts soft, grippy, and highly compliant.
- 03It is the least forgiving flexible grade to feed and detail.
- 04Use it for soft grips, pads, and protective contact surfaces.
In our shop
We treat TPU 85A as a material-and-geometry conversation, not a drop-in rubber substitute.
Simple, open forms print far more predictably than intricate enclosed shapes.

Design notes
- Keep wall transitions smooth and avoid hard corners in flexing areas.
- Bring the mating material and compression intent to review.
Technical values appear only after we approve a datasheet for the exact spool in use. If a specific property determines the job, tell us and we will discuss the material route.
