摘要: A multi-layer sheet is formed of a urethane film extruded onto a textured substrate. The film and substrate are pressed together causing the film to adopt the texture of the substrate. The substrate can be peeled away from the film leaving a textured, non-tacky surface.

摘要: A two-layer material suitable for use as a barrier layer for a cushion sock in a foam-in-place process is formed by bonding a discontinuous adhesive layer to a pinhole-free, lubricant-free barrier layer. The discontinuous adhesive layer has a melting temperature higher than 180 degrees Fahrenheit. A foam cushion is molded adjacent the cushion sock by first attaching a barrier layer to the cushion sock, and vacuum drawing the cushion sock attached to the barrier layer over a mold. The cushion sock and the barrier layer are then heated to a temperature no higher than 400 degrees Fahrenheit to bond the cushion sock and the barrier layer together.
