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.

Abstract: Silicone compositions are described for the production of negative molds that include a silicone elastomer. The molds can be used in the production of molded articles.

Abstract: Organopolysiloxane compositions are described that are crosslinkable by polyaddition and that can produce a silicone elastomer foam (or “silicone foam”) having a low density, i.e. a density of less than 0.20 g/cm3, and having good mechanical properties and a good fire resistance.

Abstract: A process is provided for preparing composite articles composed of a rigid glass, metal or thermoplastic resin substrate and of a silicone elastomer with good mechanical properties and good adhesion between the substrate and the silicone elastomer E such that there is a solid bond between the two parts. The composite articles are used in very diverse fields such as electrical and electronic equipment, motor vehicle and medical equipment, and they may be found, for example, in household appliances, consumer goods, medical equipment and sports and leisure articles.

Abstract: A method for producing a porous silicone material including the following steps: 1) implementing a direct emulsion E of silicone in water including: A) a silicone base A crosslinkable by polyaddition or polycondensation; B) at least one nonionic silicone surfactant B having a cloud point between 10 and 50° C.; C) optionally, at least one catalyst C; and D) water; 2) heating the emulsion E to a temperature greater than or equal to 60° C. to obtain a porous silicone material; and 3) optionally, drying the porous silicone material.

Abstract: The present invention concerns novel polyorganosiloxane compositions that can be hot-vulcanised into silicone elastomers, i.e. that can be vulcanised at temperatures generally in the region of between 100° and 200° C. and, if necessary, up to 250° C. The invention also concerns the use of these compositions for the production of casings or primary insulators used to form electrical wires or cables protected against fire. The invention finally concerns the electrical wires or cables protected against fire that are produced using said compositions.
