Hi

I'm looking for information about hydrolitic ageing on PET.
The Goal is to assure a lifetime of 125microns sheet of PET.
The average climate will be 30°C / 50° RH.

I want to know what will be the degradation under combined thermal (up to 80°C) & humidity (up to 95%RH) sollicitation.

I think about hydrolyse effect? Is there other effect that could appear? What kind of tests will analyse the hydrolyse effect? How can i define the accelerated factor?

Is there standards/books about ageing on PET?

Thanks
