We are exploring why amorphous thermoplastics can provide good resistance to concentrated anolyte and combat the attacks of the catholyte environment. Robust brine solutions, sodium hydroxide, hypochlorous acid, sodium hypochlorite, and hydrochloric acid are some of the contributors common to Chlor-Alkali facilities. We will discuss polymer chain chemistry while looking at historical performance environments in the Chlor-Alkali industry. Costs of corrosion, poor fabrication, and installation can be enormous, affecting the bottom line of plant productivity. We must help facilities address essential design, fabrication, and installation issues to prolong the service life while maintaining a safe operating environment.

The discussion will walk the participants through a historical progression of thermoplastics and explore the physical characteristics, polymer chemistry, and typical application range while relating the materials to recent updates in the ASME NM.1, NM.2, and ASME RTP-1 standards. American Welding Society standard, B2.4, is a crucial document that we will address on the qualification of welders, which helps us connect the theoretical with the practical. Participants will leave the presentation with a better understanding of thermoplastics and how they may improve their equipment performance in their respective facilities.
