Forgive me if im posting this in the wrong forum but I couldn't find any information on the subject and could not think of anyone better to ask :)

Instead of purchasing acrylic... I have free access to large sheets of black Acetal Delrin that I wanted to use to make frag racks, probe holders etc.

Any thoughts if it is reef safe or would have any long term chemical reactions?

UHMW (ultra high molecular weight polyethylene, I presume) is a different material than Delrin. All types of polyethylene and polypropylene are safe unless something unusual is added.

I would not use Delrin in acid as that may break it down, but reef tank water should be OK.
