Abstract
A material for clinging to smooth, impervious surfaces and supporting other objects thereon. The material includes a body of foamed polyvinyl chloride, having a foam cellular structure of about 80% closed cell foam and up to about 20% open cell foam. A flexible skin is formed on one side, the skin being unfoamed polyvinyl chloride, and having surface imperfections comprising small cavities. An adhesive layer may be formed on the opposite side to secure the body to objects mounted by the material on a smooth surface. The material bears a load in addition to the weight of the material itself when the flexible skin adheres to a vertical surface, such as a mirror or stainless steel refrigerator door.
