Good source for sheet wax in US

I am working on molding a silicone bladder, and I have been on the hunt for sheet wax but don’t know exactly what to look for or where to get it. The wax sheets will be used to duplicate the laminate thickness in a closed mold bladder setup. I have found sheet wax of varying thickness, with adhesive backing and without. The mold has a fair amount of curves and corners, so the sheets will need to be fairly workable without breaking. Hoping to find a US supplier.

Freeman manufacturing

+1 on freeman. It may be annoying to get a quote but I’ve ordered 2x boxes of sheet wax from them before.

I ran across some sheet wax in a jewelry tooling catalog today. It looked like a lot more variety in the catalog, but here’s a link to their site: https://www.riogrande.com/Search/sheet-wax
