Herb, Thanks for your reply. I will order some and give it a try. My patented product line is called Pocket Form Isolator. It forms concrete, but rather than for walls it holds concrete separate from the soil around it using injection-molded HDPE SF parts. The concrete forms are used for piers and column isolation pockets. Most of our sales are in the USA, but we do have a presence in other markets where English is spoken and the dollar is strong. Actually, my use of UHMW would be only for some low-volume "in-house" work that coworkers and I will be doing to create some molds for a totally new and completely different product line for which I am also the inventor.
