Plastic holding materials for highly basic products
Plastic holding materials for highly basic products
(OP)
My company is looking to get a new holding tank to contain both highly caustic bulk (pH > 13) as well as chlorinated products. So now the SS is out of the question, I'm wondering what sort of plastics are appropriate? I assumed that PVC would be appropriate, but have been told that it can break down at high pH and/or high temperature. Any materials or coating tips would be greatly appreciated.

Watch out of the standard FRP materials due to the High Ph, which will attack the glass. The FRP's can be used if special consideration are taken.
Come back with approximate sizes and temperatures.

Thanks for your help.

E-Brite usually is used in heat exchangers in caustic plants.
