Also known as fuzzform. A thick, fuzzy thermoplastic that when heated will fuse to form a relatively hard continuous sheet. Best molded with steam heat but because it is a non-woven and contains no woven fabric in the makeup of the product, FUZZFORM will conform to compound curves better than some of the other products. Dry heat will work, but must be used cautiously as too much can burn through the Fuzzform. Looks very much like a thin insulating fiber, or maybe wool blanket.
