Impeller Material
(OP)
Hello,
Hope you are fine there. I want to inquire about non-metallic material to be used for impeller. The impeller is to be used for caustic service having 15% concentration.

What is your max temp?
Is there a reason to not use stainless steel?
Most plastics (polyethylene, polypropylene, vinyl ester epoxy, PPS and similar thermosets) are fine with NaOH, but you cannot use a silica or glass filled one as the glass will be attacked.

Stainless steel is simple by comparison.
You will need a plastic with carbon fiber filler, it will be expensive and difficult to work with.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)
