The Hanson Group has introduced MONOCEROS, a lightweight structural material specifically designed as an economical tooling surface or lightweight structural core

The Hanson Group (Alpharetta, Ga.) has introduced MONOCEROS, a lightweight structural material specifically designed as an economical tooling surface or lightweight structural core (4 lb/ft3). Porous yet dimensionally stable, MONOCEROS is fire-retardant and chemical-resistant. As a lightweight tooling medium 1.5 inches/38.1 mm thick, MONOCEROS sheets can be bonded together using epoxy or urethane contact adhesives, and are easily machined after being surfaced with commercially available putties, pastes or sprayable coatings. MONOCEROS allows rapid heating and cooling of the tool surface and offers high-temperature stability to 350˚F/177°C maximum, 250˚F/121°C continuous, with what is said to be a negligible coefficient of thermal expansion (CTE). This patent-pending material is offered at $3.50/board-ft and available in standard 48-inch by 78-inch (1,219-mm by 1,981-mm) sheets. Custom sizes are available by special order up to 40 ft/12.2m long, 78 inches/1,981mm wide and 7 ft/2.1m thick (pre-bonded).
