Q: I’m building some lab equipment what will be housing hydrochloric acid. I need a non-metal fastener that is corrosion resistant . Can you make a recommendation?
A: In terms of a material that is not metallic and can handle hydrochloric acid, I would suggest either PTFE or PVDF. PTFE is virtually inert to most acids, as well as bases. If you laboratory is working on anything organic, it is bio-inert and will not leach into or contaminate sensitive scientific material. PVDF is also a good choice, as it offers similar resistance as PVDF to harsh chemicals, but with increased mechanical strength.
