Abstract: An acoustical panel formed from a fibrous, open-celled material comprised of up to about 50% by weight fibers, between about 3% and about 10% by weight binder, between about 20% and about 75% by weight filler and about 0.01% to about 2.0% by weight surfactant. Additionally, voids are formed within the panel having an average distribution size diameter of about 50 &mgr;m to about 250 &mgr;m. The acoustic panel achieves very high sound absorption properties without the need for additional surface perforations, while maintaining a very high surface hardness.

Abstract: A fabric covered board structure made with a base of a mineral fiber material having a corrugated face surface. A discontinuous coating of high tack adhesive on the corrugated face surface and a flexible textile or vinyl sheet adhered to the face surface by the adhesive.

Abstract: A flexible pipe covering having a seam or split along its length is placed over a water or like pipe. The seam is sealed by the use of a pressure sensitive adhesive transfer tape which is factory mounted on one side of the seam and provides a protective sheet that is removed after the flexible pipe covering is mounted in position. Upon removing the protective sheet, the pressure sensitive adhesive will be made to contact both sides of the seam and seal the seam.A similar type of adhesive joint may be formed at the butt end of two adjacent pipes.

Abstract: A decorative product constructed of polymeric materials is provided wherein the top layer of the product is a film or layer of thermoplastic polymer (e.g., polyvinyl chloride) having a relief pattern on one surface and bonded at its other surface to a base layer of a thermoplastic ethylene interpolymer (e.g., an ethylene-vinyl acetate copolymer).The product is useful as a floor or wall covering.
