And once enlarged, it doesn't come back to its original size.
Interesting!
May I ask you why you want to use TPU tubes? Is it to save weight, have very small packing spare tubes, have a lower rolling resistance...?
Yes, yes, and yes.
As already written, from what i read, the Revoloop have a better appraisal than the Tubolito and they exists in ETRTO406 for wide tires (due to the lack of elasticity of the TPU material, TPU tube width must closely match the tire width).
For stronger TPU, Tubolito has cargo TPU tubes also available for wide ETRTO406 tires (as used on many front wheel cargo bikes). But I never any review of those cargo tubolito's
I may try the cargo tubolitos - might be a good compromise between weight savings and durability.
