    摘要： A static mixer is disclosed. The static mixer comprises a housing (22) defining an internal mixing cavity (36) that longitudinally extends along a central axis between an inlet (38) and an outlet (40) and is adapted for axial flow of a fluid therethrough. The static mixer also comprises a mixing element (42) disposed within the mixing cavity (36). The mixing element (42) is configured to be free from an impingement surface oriented substantially perpendicular to a main direction of fluid flow through the internal mixing cavity (36). The mixing element (42) comprises an elongated mixing blade that is oriented longitudinally within the mixing cavity (36) and comprises a nose axially oriented toward the inlet (38). The static mixer may comprise a heat-exchanging jacket integrally formed with the housing (22). An additive manufacturing system comprising the static mixer, and methods of making and using the same, are also disclosed.

    摘要： A method of forming a three-dimensional (3D) article is disclosed. The method comprises (I) printing a first composition (14) on a deformable substrate (18) at a volumetric flow rate with a 3D printer to forma deformable first filament (16) comprising the first composition on the deformable substrate. The method further comprises (II) controlling the volumetric flow rate to reduce a deformation force applied by a nozzle (12) of the 3D printer to the deformable substrate (18) and give a first layer comprising the deformable first filament (16) on the deformable substrate. In the method, (I) and (II) may optionally be repeated with independently selected composition(s) to form any additional deformable filament(s) and corresponding layer(s). Finally, the method comprises (III) exposing the layer(s) to a solidification condition. A 3D article formed in accordance with the method is also disclosed.

    摘要： A method of forming a porous three-dimensional (3D) silicone article is disclosed. The method comprises I) printing a first composition with a 3D printer to form a first layer from the first composition. The method further comprises II) printing a second composition on the first layer with the 3D printer to form a second layer from the second composition on the first layer. At least one of the first and second compositions comprises a silicone composition. In the method, step II) may optionally be repeated with independently selected composition(s) for any additional layer(s). At least one of the first and second layers does not consist of linear filaments. Finally, the method comprises III) exposing the layers to a solidification condition. The porous three-dimensional (3D) silicone article defines a plurality of voids.

    摘要： A networked silicone is disclosed. The networked silicone comprises crosslinked strands of hindered organosilicon compounds. A composition for preparing the networked silicone is also disclosed, and comprises (A) a hindered organosilicon compound, (B) a crosslinking compound, and optionally (C) a catalyst. Additionally, a method of preparing the networked silicone is disclosed, and comprises reacting the hindered organosilicon compound (A) and the crosslinking compound (B), optionally in the presence of the catalyst (C), to give the networked silicone. A reaction product comprising the networked silicone is also disclosed. The reaction product is prepared from the composition and/or in accordance with the method, and may be a cured product. Additionally, a composite article and a method of forming the same are disclosed. The composite article is formed by disposing a networked silicone composition on the substrate and curing the networked silicone composition, thereby preparing the composite article.

    摘要： A composition for forming a silicone elastomer is disclosed. The composition comprises: A) a linear organopolysiloxane having at least two silicon-bonded ethylenically unsaturated groups per molecule; B) a linear organohydrogensiloxane having at least two silicon-bonded hydrogen atoms per molecule; C) at least one cross-linker; and D) a hydrosilylation catalyst. The cross-linker C) is selected from the group consisting of: C1) an organopolysiloxane having at least three silicon-bonded ethylenically unsaturated groups per molecule; and C2) an organopolysiloxane having at least three silicon-bonded hydrogen atoms per molecule. At least one of the silicon-bonded ethylenically unsaturated groups of component C1) has a lower reactivity relative to the silicon-bonded ethylenically unsaturated groups of component A). Moreover, at least one of the silicon-bonded hydrogen atoms of component C2) has a lower reactivity relative to the silicon-bonded hydrogen atoms of component B). Methods of forming three-dimensional (3D) articles utilizing the compositions are also disclosed.
