HDU Foam, 30 Pound, 1 Square Foot
High-Density Urethane (HDU) is usually available from Sign Supply Companies in 4 x 8 foot sheets and is normally not sold in less than one-full-sheet quantities. HDU is a unique, but expensive product on its own, but adding the cost of freight prices it out of the reach of the small business owner and hobbyist. HDU is a wonderful material for hand carving, shaping, and machining. It is used for mold-making, furniture details, toys, prototyping, models, die-making, and, of course, signs. Perfect for CarveWright, other CNC machines, and power routers. HDU paints and stains easily.
