Aliphatic vs Aromatic TPU — Decision Helper

Aliphatic vs Aromatic TPU — Decision Helper | Tengyang

1. Is the part light-coloured, white, or optically clear where a yellow cast would show?

Yes — a colour shift would be visible and unacceptable No — the part is dark, opaque, or hidden

2. Does the part see sustained outdoor or ultraviolet exposure in service?

Yes — outdoor, automotive exterior, or long UV exposure No — indoor or short exposure

3. What does one field colour failure cost you?

A recall, rework campaign, or warranty claim A rejected assembly at the line Cosmetic only, low consequence

4. Is the service also hot and humid (wash-down, tropical, autoclave)?

Yes — humidity is a factor No — dry service
