  • Method for manufacturing a silicone elastomer article using a 3D printer
    Patent number: 11884001
    Abstract: The invention relates to an additive manufacturing method for producing a three-dimensional elastomer silicone article. The elastomer silicone article is built up layer by layer by printing a silicone composition crosslinkable by addition reactions comprising at least one organopolysiloxane-polyoxyalkylene copolymer with a 3D printer selected from an extrusion 3D printer or a material jetting 3D printer.
    Type: Grant
    Filed: May 9, 2018
    Date of Patent: January 30, 2024

  • BINDER FOR INJECTION MOULDING COMPOSITION
    Publication number: 20230234891
    Abstract: A binder for an injection moulding composition, the binder includes, in percentage by mass and for a total of 100%: 35% to 60% of a component (a), or polymer base, made of a polymer or a mixture of polymers, each of the polymer being non-amphiphilic and having a mass average molar mass greater than or equal to 5,000 g/mol, 30% to 55% of a component (b), or wax, made of a polymer or a mixture of polymers, each of the polymer being non-amphiphilic and having a mass average molar mass less than 5,000 g/mol, and less than 10% of an amphiphilic component (c), or surfactant, and less than 10% of other components (d). The polymer base comprising 2% to 15% of a styrene-ethylene-butylene-styrene copolymer (SEBS), in percentage by mass based on the mass of the binder.
