3m Reinforced Polyurethane Foam


New from 3M is its new Reinforced Polyurethane Foam, an economical and lightweight alternative to plywood. In applications such as marine, transportation, and general construction, these polyurethane foam boards with fiberglass reinforcement can save 30 to 60% of weight per board compared to plywood.

The Reinforced Polyurethane Foam is available in five densities ranging from 15 pounds per cubic foot to 26 pounds per cubic foot, completing 3M’s existing line of lighter density foam boards. 

Reinforced Polyurethane Foam comes in 4 foot by 8 foot sheets that provide users with plane, level boards that are easy to work with and won’t warp. With its innovative foam, 3M can easily shape the material with tools and secure it with screws as opposed to plywood, which can crack or pop during construction. Besides it’s inherent rot resistance, reinforced polyurethane foam’s low moisture content provides it with superior adhesion over wood.

According to Nick Harris, global business leader for 3M Engineered Products and Solutions, plywood is currently used in many applications where water causes it to degrade over time. “3M Reinforced Polyurethane Foam not only offers manufacturers a more durable alternate to plywood, but it contributes to weight reduction as well.”
