PTFE is exposed to hot concentrated sulfuric acid and was found blistering . Based on my undestanding, plastic materials are permeable and can contain microvoids, which are the possible main contribuitng factors of blistering.
However, are there other possible contributing factors or main causes of blistering that I have missed?
Dear Dr. Hussam Alnammary,
in order to clarify the possible causes of PTFE blistering in your experimental conditions, I suggest you take a look at what is indicated on the note PTFE Properties, available at: https://www.ptfeplastics.com/ptfe-properties/
Best regards, Pierluigi Traverso
Check " Isocorrosion diagrams"... PTFE lined flow systems are common in sulphuric acid industry.. ex: Procedia Engineering,138, ( 2016 ), 421– 426
Due to the processing kind PTFE parts may have a higher or lower porosity, regarding sintering. Therefore the bilstering in certain media is possible. Sintering at high pressures no pores are detectable. May be there is no blistering with that kind of material
