Abstract: A sports board, particularly a body board, for surfing purposes, which board is a preformed, preshaped foam board composed of closed-cell foam material, with an inner core of low density foam material and an outer core of foam material of greater density than the inner core. The board has a top and bottom surface and two sides, the sides containing outwardly extending angular side rails thereon, extending from one to the other end of the board, and around the front of the board. The board includes an integral thermoplastic polymer film material heat-laminated only to the bottom surface of the board, and to the lower side rail surface of the board. The polymer film material provides a low-frictional bottom surface and lower side rail surface and provides for enhanced mechanical stiffening of the board.

Abstract: A multicolored foam product and a method for the preparation thereof. Heat-plastified foamable gel of a thermoplastic resin or resins containing blowing agents are combined with different coloring materials added sequentially and extruded through an orifice of a die which is extended in length to facilitate laminar flow in the resin. This resin is expanded to form a multicolored layered foam product, such as multicolored foam planking, in a single extrusion. Multicolored foam planking produced is suitable for use as the body material for surfboards, body boards, and other recreational products.
