Art-Mat Densified Embossed foams are manufactured by compression under high heat to form and attractive textured pattern. This increases the surface area, density and stiffness of the foam for maximum sound absorption. By densifying the surface a thin skin is formed to give greater abrasion and air velocity resistance. A decorative urethane facing can be applied (Type Deco-Foam CF) for enhanced appearance and durability and to make the foam impervious to most liquids. Acousti-Mat Embossed Foams are typically used in business equipment, appliances, HVAC units and vehicle headliners.
