Patent number: 8741427Abstract: A microcavity-containing, resilient foam comprising a thermoplastic polymer; composite structures comprising such a microcavity-containing foam and a multiplicity of particles contained in such microcavities, preferably aqueous fluid absorbent particles; methods for preparation of such foam and structures; and disposable consumer articles incorporating such foams and composites. The aqueous fluid absorbent characteristics of the foam and composite structures render them useful in the fabrication of disposable consumer articles, in particular hygiene articles designed to rapidly absorb “insults” of bodily fluid thereby conducting such fluids away from contact with the skin of the wearer of the hygiene article. The useful articles include infant and children diapers, adult incontinence pants, feminine hygiene pads, pet urine-absorbent pads and mats, household cleaning pads, surgical drapery, and the like.Type: GrantFiled: July 13, 2006Date of Patent: June 3, 2014Assignee: Dow Global Technologies LLCInventors: Young-Sam Kim, Luther E. Stockton, Mark W. VanSumeren

Publication number: 20140147657Abstract: A two-layer mono-axially oriented film includes a first layer of an opaque beta-nucleated microvoided propylene-based polymer; and a second layer containing a dark pigment that is adapted for use in a thermal printer in which the thermal print-head contacts the exposed surface of the first layer. The dark pigment of the second layer pigment has a color contrasting with the color of the first layer and can contain a carbon black. The first layer includes microvoids and may be made transparent upon the application of heat by collapsing the voids of the first layer or upon the application of ultra-sonic energy.Type: ApplicationFiled: April 5, 2013Publication date: May 29, 2014Applicant: Toray Plastics (America), Inc.Inventor: Toray Plastics (America), Inc.

Patent number: 8728594Abstract: A heat-shrinkable white polyester film is provided which has extremely satisfactory cuttability along a perforation and has light-shielding properties. Also provided are: a label; and a process for producing the film with high productivity. The heat-shrinkable white polyester film comprises a polyester resin constituted of ethylene terephthalate as a main constituent component and containing at least 13 mol % one or more monomer ingredients capable of serving as an amorphous component among all components of the polyester resin. This film has specific heat shrinkability, specific light-shielding properties, and specific mechanical properties. The process is excellent in the productivity of the film. The label is obtained from the heat-shrinkable white polyester film.Type: GrantFiled: February 24, 2009Date of Patent: May 20, 2014Assignee: Toyo Boseki Kabushiki KaishaInventors: Masayuki Haruta, Masatoshi Hashimoto, Yukinobu Mukoyama, Katsuhiko Nose

Patent number: 8728617Abstract: Provided is a microporous material, e.g., a microporous sheet material, having a matrix of polyolefin, finely-divided, substantially water insoluble particulate filler, a network of interconnecting pores communicating throughout the microporous material, and at least one retrospectively identifiable taggant material embedded within the matrix, optionally the at least one taggant being unique to an end user for the microporous material, wherein the polyolefin is present in the microporous material in an amount of 20 to 35 weight percent, based on the weight of the microporous material. The taggant material provides a marker, signature or code that is capable of retrospective identification by machine, instrument or by the naked eye. Articles including the microporous material and processes for preparing the microporous material also are provided.Type: GrantFiled: December 17, 2010Date of Patent: May 20, 2014Assignee: PPG Industries Ohio, Inc.Inventors: Paul L. Benenati, James L. Boyer, Charles R. Coleman, Luciano M. Parrinello, Narayan K. Raman

Patent number: 8722196Abstract: Proposed are a composite material having a high adhesiveness, wherein non-penetrating pores that are formed in a silicone surface layer are filled up with a metal or the like without leaving any voids by using the plating technique and the silicone surface layer is coated with the metal or the like, and a method of producing the composite material. A composite material, which has a high adhesiveness between a second metal or an alloy of the second metal (106a, 106b) and a silicone surface, can be obtained by filling up non-penetrating pores that are formed in the surface of a silicone substrate (100) substantially with a second metal or an alloy of the second metal (106a) with the use of the autocatalytic electroless plating technique wherein a first metal located at the bottom of the non-penetrating pores as described above serves as the starting point, and coating the surface of the silicone substrate (100) with the second metal (106b).Type: GrantFiled: March 2, 2009Date of Patent: May 13, 2014Assignee: Japan Science and Technology AgencyInventors: Shinji Yae, Tatsuya Hirano, Hitoshi Matsuda
