TPE-U means thermoplastic polyurethane.
Why choose it?
- Good abrasion resistance
- Performance in low temperatures (polyether type)
- High shear strength
Why not choose it?
- Some types – especially softer ones – might have migration problems that make the surface either hard or sticky in extended use. Please share your experiences if you have encountered this phenomenon!
Typical applications:
- Wheels
- Conveyor belts
- Sport shoes
Please note:
TPE-U comes in two main variants: polyester and polyether, which are suitable for different purposes. Polyester is more common; polyether is used in low temperatures or in long term contact with water. The aliphatic version of TPE-U has, in my experience, good UV resistance. For more information about the different TPE-U variants, I find the Huntsman TPE-U leaflet informative.
