  • Plastic molding composition and sintered product
    Patent number: 9738785
    Abstract: A plastic molding composition includes a powder, gelatin, a polar solvent, and an adhesion reducer. The powder contains at least one of a ceramic particle and a metal particle. The adhesion reducer reduces adhesion of the gelatin so that a molded product, which is molded from the composition with a molding die, is removed from the molding die without being broken. The adhesion reducer is a water-soluble or water-dispersible compound. The adhesion reducer has a HLB value, calculated by Griffin's method, ranging from 10 to 20.
    Type: Grant

  • PLASTIC MOLDING COMPOSITION AND SINTERED PRODUCT
    Publication number: 20150209979
    Abstract: A plastic molding composition includes a raw powder, gelatin, a polar solvent, and a plasticizer. The raw powder contains at least one of a ceramic particle and a metal particle. The plasticizer reduces the minimum amount of the solvent necessary to give flowability to the composition. The plasticizer is a water-soluble or water-dispersible compound. The plasticizer has a ratio of hydroxyl number to carbon number per molecule in a range from 8% to 100%. The plasticizer is in solid or liquid form. When the plasticizer is in liquid form, the plasticizer has volatility equal to or lower than volatility of water.
