Hi,

Since the tensile strength for PHB/s limits to around 400 bar therefore, beyond this pressure it will certainly break. But it depends on other physical parameters too.

Ariadna Pié

Ok, thanks a lot!!

Andrei Rogoza

Ariadna Pié , idea of Suchin about relation of chemical stability and tensile strength is really exotic, I am sorry for him.

Anyway, some reason to trouble is exist. PET (polyethyleneterephthalate) undergo solvolisys in supercritical CH3OH (500oC and some hundreds atm). Be quiet if you have non-protic solvent and much lower temperatures.
