  • Patent number: 8962749
    Abstract: The invention provides a ceramic green sheet having plasticity, punching property, and sinterability of satisfactory levels as well as a low percent (heat) shrinkage. In the production of a ceramic slurry serving as a raw material of the sheet, ingredients thereof are mixed under such conditions that the functional group ratio (polyol to isocyanate) is 1.5/11.5 to 11.5/11.5; the urethane resin formed from isocyanate and polyol has a repeating-unit-based molecular weight of 290 to 988; and the ratio by weight of the urethane resin to a ceramic powder falls within a range of 4.5 to 10 parts by weight of the urethane resin with respect to 100 parts by weight of the ceramic powder. A ceramic green sheet having, in well balance, all of the properties (i.e., plasticity, punching property, sinterability, and (heat) shrinkage) required for facilitating subsequent processes such as mechanical working and firing can be provided.

  • Patent number: 8389117
    Abstract: Disclosed are hot-melt adhesives prepared from polyesters containing 1,4-cyclohexane-dicarboxylic acid as a diacid component and a diol component containing at least two diols chosen from 1,4-cyclohexanedimethanol, triethylene glycol, and diethylene glycol. These adhesives set up rapidly within a well-defined temperature window. The hot-melt adhesives can be used in a variety of applications, but are especially suited as seaming adhesives for roll-applied labels. These adhesives have melting temperatures and crystallization properties that allow their application at temperatures cool enough to prevent curling and premature shrinkage of the shrink label during seaming, and yet produce strong label seams that can withstand the elevated temperatures of a shrink tunnel without sacrificing line speed. Also disclosed are labeled containers and a process for applying a roll-on, shrink label to a container using the hot-melt adhesives of the invention.

  • Publication number: 20080026180
    Abstract: A flexible substrate is described herein which is made from a freestanding inorganic material (e.g., mica paper, carbon paper, glass fiber paper) with pores/interstices that have been impregnated with a special impregnating material (e.g., silsesquioxane, alkali silicate glass with weight ratio of SiO2/X2O (X is alkali Na, K etc.) between 1.6-3.5). In one embodiment, the flexible substrate is made by: (1) providing a freestanding inorganic material; (2) providing an impregnating material; (3) impregnating the pores/interstices within the freestanding inorganic material with the impregnating material; and (4) curing the freestanding inorganic material with the impregnated pores/interstices to form the flexible substrate. The flexible substrate is typically used to make a flexible display or a flexible electronic.
