A method of preparing a cured air spring bellows includes preparing a vulcanizable composition including a eutectic composition by mixing a vulcanizable elastomer, a sulfur-based curative, zinc oxide, and a eutectic composition; preparing a green member using the vulcanizable composition; and curing the green member to form the air spring bellows.

An article comprises a laminate with a layer comprising a first latex composition containing a cross-linker component selected from sulfur, organic peroxide, vulcanizing activators, and vulcanizing accelerator; and a second layer comprising a second latex composition free of the cross-linker component. The laminate is formed by dipping a mold into the first latex composition then into the second latex composition forming a laminated film, then curing the laminated film by heating to a temperature between 90° C. to 140° C. Lastly, the laminated film is removed from the mold via inversion such that the second layer is inwards and the first layer is outwards.

The present disclosure provides, among other things, surface coverings with a protective coat applied thereto a rubber material. As provided herein, in some embodiments, a surface covering has or includes an exposed surface that is no-wax. The present disclosure further provides methods of making, and methods of using. Such surface coverings have surprising and beneficial attributes. They are particularly advantageous as resistant to soiling and abrasion. These surface covering are also resistant to crumbling under load. Such surface coverings would be useful as flooring products with desirable properties. In particular, such abrasion and soil resistant surfaces could be useful as a rubber flooring product.

Cyclic olefin copolymer (COC) is useful as a build material for 3D printing, especially desktop 3D printing.

A method for producing a three-dimensional construction material component preferably having at least one curved surface. A plurality of spacers are arranged in a formwork. A textile reinforcement is supported on the spacers, such that the textile reinforcement has a defined position within a formwork interior of the formwork. A tensile force is applied via a tensioning device to the textile reinforcement in at least one tension direction. Construction material is introduced into the formwork interior and surrounds the textile reinforcement. The construction material is then hardened, wherein the tensile force is maintained during the hardening. During this process, the spacers are integrated into the construction material component. The tensioning device has at least one clamping unit for clamping an end portion of the textile reinforcement between two clamping surfaces. The clamping surfaces are provided on clamping insert bodies, which are of a plastic material of a defined hardness.

A high-frequency dielectric heating adhesive sheet includes an adhesive layer. The adhesive layer contains a thermoplastic resin having a reactive site, a dielectric filler that generates heat upon application of a high-frequency electric field, and a silane coupling agent.

A two-part masterbatch comprising: a first part comprising an unsaturated thermoplastic polymer, wherein the first part (typically, the unsaturated thermoplastic polymer of the first part) has an iodine value of at least 10; and a second part comprising an oxygen scavenging catalyst; packaging articles (e.g., preforms and plastic containers), and methods.

A composition for a direct ink writing includes a polymeric component in latex form, where the latex includes greater than 75% solids content; and additives adapted to provide the composition with capability of being utilized as a rubber ink formulation for the direct ink writing process. A method of producing an additive manufacturing product includes steps of providing an initial polymeric component in latex form, where the initial polymeric component in latex form includes from about 50% to about 70% solids content; removing water from the initial polymeric component in latex form to thereby form a subsequent polymeric component in latex form, where the subsequent polymeric component in latex form has greater than 75% solids content; and mixing the subsequent polymeric component in latex form with additives adapted to provide a rubber ink formulation composition; and additive manufacturing the rubber ink formulation composition to thereby form a green component.

Embodiments of the present disclosure generally relate to reinforcement and filler materials in various compositions, and more specifically to coal-derived materials as reinforcement and filler materials. In an embodiment, a composition includes a coal-derived component and an elastomer component. The coal-derived component can be coal powder and/or coal char. The coal-derived component can be thermally-treated (e.g., pyrolyzed), solvent-extracted to produce an extract or residual carbon, and/or chemically modified prior to incorporation in the composition.
