  • Publication number: 20240132705
    Abstract: An object of the present disclosure is to provide a rubber composition from which a crosslinked rubber molded product having excellent resilience performance can be obtained. The present disclosure provides a rubber composition containing (a) a base rubber, (b) a co-crosslinking agent, and (c) a crosslinking initiator, wherein (b) the co-crosslinking agent includes (b1) a metal complex, and (b1) the metal complex is composed of (b11) a metal component, (b12) a ligand derived from an ?,?-unsaturated carboxylic acid compound having 3 to 8 carbon atoms, and (b13) a ligand derived from a mercaptobenzothiazole-based compound.

  • Publication number: 20210205061
    Abstract: Provided is an occlusal pressure analysis program capable of improving the accuracy of grasping the occlusal contact state in occlusal pressure acquisition by a pressure detection means, including a step of obtaining a pressure value for each minimum unit from which the pressure value can be recognized by a pressure detection means, and a step of, regarding each of the minimum units where the pressure value exists as a detection unit, separating the detection units into the detection units which can be regarded as due to occlusion and the detection units which are unclear whether they are due to occlusion, based on the pressure value.

  • Patent number: 6845823
    Abstract: The present invention provides a foam fire-extinguishing agent devoid of environmentally harmful fluorochemical surfactant. The foam fire-extinguishing agent comprises a foamable synthetic surfactant consisting of (a) polyoxyethylene alkyl sulfate ester salt, and (b) at least either one of lauric acid amide propyldimethyl amino betaine acetate and lauric acid amide propylhydroxy sulfobetaine. This foam fire-extinguishing agent may further include at least either one of (c) polyoxyalkylenediamine having both terminal ends substituted with amino alkyl, and derivatives thereof, (d) polyoxyethylene coconut fatty acid monoethanol amide phosphate ester and (e) dodecyl alcohol.

  • Patent number: 6379578
    Abstract: A water-based foam fire extinguisher excellent in foaming properties and film-forming properties in a low temperature region which includes an aqueous solution of at least one member selected among potassium hydrogen carbonate, ammonium phosphate, ammonium sulfate, ammonium bromide, boron oxide, and potassium tetraborate and, incorporated in the solution, a freezing point depressant so as to have a freezing point of −20° C. or below, characterized by containing a perfluoroalkylbetaine as a fluorochemical surfactant and one or more amide-amino acid type surfactants represented by general formula (1) and/or (2) (wherein R1 represents C7-23 alkyl, hydroxyalkyl, aralkyl, or alkenyl; and X represents an alkali metal or hydrogen) as hydrocarbon surfactants.
