Thank-you All,
I have 2 questions I would like to have guidance on:
1) Can anyone pl. suggest and work done on the condensation through a polymeric barrier (say virgin PTFE) by means of Permeation of process fluid (at steam) at elevated pressure and temperature. I am specifically looking for the approach to measure and estimate.
2) Can anyone pl. let me know a vendor who produces a virgin PTFE (Teflon or equivalent) rod with traceability of its physical and electrical properties either to a ASTM or equivalent standard.
cheers,
bssem
