MULTIPLAYER MATERIALS WITH ADHESIVE AND PRODUCTION THEREOF |
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 are then heated to a temperature no higher than 400 degrees Fahrenheit to bond the cushion sock and the barrier layer together. |
