A skate (e.g., an ice skate) for a skater (e.g., a hockey player). The skate comprises a skate boot for receiving a foot of the skater and a skating device (e.g., a blade and a blade holder) disposed beneath the skate boot to engage a skating surface (e.g., ice). At least part of the skate boot and optionally at least part of one or more other components (e.g., the skating device) may be constructed from one or more materials (e.g., foams) molded by flowing in molding equipment during a molding process (e.g., injection molding or casting). This may allow the skate (or other footwear) to have useful performance characteristics (e.g., reduced weight, proper fit and comfort, etc.) while being more cost-effectively manufactured. Other articles of footwear are also provided.

The invention relates to an additive manufacturing process for producing a silicone elastomer item. In particular, the invention relates to an additive manufacturing method for producing a silicone elastomer item from a photocrosslinkable silicone composition. The invention also relates to a photocrosslinkable silicone composition.

In a golf ball having a core composed of one or more layer, the outermost layer of the core is formed of a rubber composition containing a base rubber and an α,β-unsaturated metal carboxylate, an envelope layer directly encasing the core is formed of a resin composition containing a thermoplastic resin having a structure that includes α,β-ethylenically unsaturated carboxylic acid copolymerization units which accounts for at least 50 wt % of the resin composition, and a surface of the core outermost layer and the envelope layer adjoin each other through an intervening oxazoline group-containing substance. The golf ball has improved adhesion between the rubber-based core and the cover layer that directly encases the core and is formed of an ionomer resin or other α,β-ethylenically unsaturated carboxylic acid copolymer-containing resin material.

A gasket is disclosed for use as an environmental seal between a first aircraft part having planer surface and a second aircraft part having a planer surface, the two planer parts spread apart and engaged with fasteners. The gasket, in some embodiments, is compressible between the planer surfaces. The gasket, in some embodiments, comprises a first tabular portion having tabular portion properties and having a first tabular thickness and a length and a width, the length and width much greater than the first tabular thickness; and a second tabular portion having tabular portion properties having a second tabular thickness, a length and width, the length and width much greater than the second tabular thickness; and a tabular skeleton. The first and second tabular portions and the skeleton are positioned parallel to one another. The skeleton is at least partly contacting one of the tabular portions. The first tabular portion and the second tabular portion differ in at least one tabular portion property.

In one aspect, inks for use with a three-dimensional printing system are described herein. In some embodiments, an ink described herein comprises up to about 90 wt. % monofunctional curable material, up to about 10 wt. % difunctional curable material, and up to about 10 wt. % liquid rubber, based on the total weight of the ink, wherein the liquid rubber comprises one or more curable moieties. In some cases, the liquid rubber comprises one or more ethyleneically unsaturated moieties. For example, in some instances, the liquid rubber comprises a butadiene acrylonitrile copolymer.

A hose that includes an inner layer and an outer layer made of an elastic polymeric material, and a textile reinforcement layer interposed between the inner and the outer layers. The inner layer and the outer layer are reciprocally coupled to form a unitary tubular member, within which the textile reinforcement layer is embedded. The unitary tubular member has an elasticity such to automatically elongate under the working pressure given by the liquid flowing therethrough to increase its original length and to automatically recover once the working pressure stops. The textile reinforcement layer is adapted to move from a rest configuration when the working pressure stops to a working configuration when the unitary tubular member elongates under the working pressure, and vice versa.

Methods for manufacturing articles of footwear are provided. In various aspects, the methods comprise utilizing additive manufacturing methods with foam particles. In some aspects, the additive manufacturing methods comprise increasing the temperature of a plurality of foam particles with actinic radiation under conditions effective to fuse a portion of the plurality of foam particles comprising one or more thermoplastic elastomers. Increasing the temperature of the foam particles can be carried out for one or multiple iterations. The disclosed methods can be used to manufacturer articles with sub-regions that exhibit differing degrees of fusion between the foam particles, thereby resulting in sub-regions with different properties such as density, resilience, and/or flexural modulus. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

The invention relates to a radiation-curable silicone composition for additive-manufacturing technology comprising mercapto-functional polyorganosiloxane(s) as Component A, organosiloxane(s) with at least two aliphatic unsaturated carbon-carbon moieties as Component B, photo-initiator(s) as Component C for initiating a curing reaction between Component A and Component B, dye(s) as Component D dissolved in mercapto-functional polyorganosiloxane(s) as Component E, the mercapto-functional polyorganosiloxane(s) having a fraction of (mercaptoalkyl)methylsiloxane units of at least 50 mol %, wherein Component D is dissolved in Component E before Component D is combined with the other components of the radiation-curable silicone composition. The invention also relates to a process of producing a radiation-curable composition wherein the process comprises the steps of providing a solution of dye(s) in a composition comprising mercapto-functional polyorganosiloxane(s) having a fraction of (mercaptoalkyl)methylsiloxane units of at least 50 mol %, combining the solution containing the dye(s) dissolved in the mercapto-functional polyorganosiloxane(s) with mercapto-functional polyorganosiloxane(s), organosiloxane(s) with at least two aliphatic unsaturated carbon-carbon moieties, photo-initiator(s) for initiating a curing reaction between Component A and Component B, optionally filler(s), stabilizer(s) and additive(s).

A non-conductive rubber hose is provided exhibiting lower conductivity compared to conventional EPDM hose, and reduced stiffness compared to conventional non-conductive thermoplastic hose. The hose is useful for applications such as in hydraulics for boom trucks, and for coolant in plasma cutting tools.

Provided are a support with an antibacterial layer, which exhibits excellent followability with respect to a curved surface and in which peeling does not easily occur between a support and an antibacterial layer even though the support with an antibacterial layer is bonded to a curved surface, and a laminate including the support with an antibacterial layer. The support with an antibacterial layer of the present invention includes a support and an antibacterial layer disposed in at least a portion on the support, in which the support contains a urethane resin, and the antibacterial layer contains a hydrophilic polymer and an antibacterial agent.
