Patent number: 7244489Abstract: There is provided a multi-layered foamed article. The foam article has a layer of foam material on either side of an inner peel layer disposed roughly in the middle of the foam. The portion of the foam in closest proximity to the peel layer is subjected to the greatest amount of heat during extrusion forming mostly large open cell foam. The foam near the surface of the multiplayer foam article is cooled by the atmosphere or contact with cooling surfaces and comprises mostly small closed-cell foam. There is also provided a method for making a multi-layer foamed article by co-extruding an inner peel layer sandwiched between two expanded layers of a foam material. Each of the expanded foam layers on either side of the peel layer of the article is easily peeled or stripped from the peel inner layer and the multi-layer article is converted into a foamed article with absorbing characteristics on one side and non-absorbing characteristics on the other side.Type: GrantFiled: May 12, 2003Date of Patent: July 17, 2007Assignee: Cryovac, Inc.Inventor: Joseph E. Owensby

Patent number: 7214420Abstract: A longitudinally extending cellular body of a wood plastic composite is disclosed. The body has at least one wall which extends at least substantially the longitudinal length of the body, and encloses a central cavity which extends a distance that is less than the longitudinal length of said body. The cellular body has an impervious integral skin and has an exterior surface which is smooth to the touch. The surface has voids and has the appearance of wood. When the cellular body is struck, it makes a sound like the sound of a piece of wood being struck.Type: GrantFiled: May 23, 2005Date of Patent: May 8, 2007Inventor: Robert Joyce

Patent number: 7214424Abstract: A heat-peelable adhesive sheet which shows small increase in the degree of contamination caused by a heat treatment for lowering an adhesive force is disclosed. The heat-peelable pressure sensitive adhesive sheet comprises a heat-expandable layer containing heat-expandable microspheres and expanding upon heating, and a non-heat expandable pressure-sensitive adhesive layer formed on at least one side thereof. The heat-peelable pressure-sensitive adhesive sheet can achieve the desired adhesive properties such as an excellent adhesive force before heating and also show a quick lowering of the adhesive force upon heating. Further, it shows small increase in the degree of contamination due to the treatment for lowering the adhesive force. Due to those characteristics, the heat-peelable pressure-sensitive adhesive sheet is practically applicable to, for example, the production of electronic parts made of thinner semiconductor wafers.Type: GrantFiled: April 17, 2002Date of Patent: May 8, 2007Assignee: Nitto Denko CorporationInventors: Kazuyuki Kiuchi, Toshiyuki Oshima, Akihisa Murata, Yukio Arimitsu
