Dear experts, I would like to know which material would be suitable to store 93-96% sulphuric acid with a temperature range of 5-20 degrees C. However, the temperature could well exceed 40 degrees C at certain times of the year. I am leaning towards PTFE for this concentration of sulphuric acid and at this temperature. I am basically looking for reasons to choose PTFE over HDPE. If anyone is in preference of HDPE, I would be also interested to know why they would think that HDPE is suitable for storage of sulphuric acid at 93-96% concentration 5/20 degrees C. I look forward to your responses. Thanks in Advance. Ndi77

Ndi77: We would be comfortable with the selection of PTFE for your stated application. We would have to do some investigating regarding the upper temperature limits for HDPE in sulrufic acid. Maybe one of our visitors has some personal experience with your preferred choice. Thanks for posting! David Hendrix The Hendrix Group Inc.
