<p>An intimate and dimensionally stable bond between thermally insulating foamed materials and heat exchange members, such as refrigeration equipment coils, is obtained by inserting between the heat exchange members and the gap provided for receiving the thermally insulating foamed material, a sheet or tape of olefin polymer material, adhesive-treated on a single side thereof, and comprising a lubricating agent able to migrate to the surface to assist in providing an intimate contact between the polyurethane and the support material, making mutual adaptation easier during the foaming expansion step.</p> |
