Provided is a rubber composition capable of providing rubber parts improved in adhesiveness, a rubber composite improved in adhesion force at an adhesion site of rubber parts, and a rubber crawler having improved adhesion force at an adhesion site of the rubber parts. The disclosed rubber composition contains at least a polymer component: in which the polymer component contains a styrene-butadiene rubber-containing component including either a styrene-butadiene rubber alone or a mixture of a styrene-butadiene rubber and a butadiene rubber; a styrene content in the styrene-butadiene rubber-containing component is less than 20 mass %; and the styrene-butadiene rubber is oil-extended styrene-butadiene rubber. Further, the polymer component of the disclosed rubber composition contains less than 50 parts by mass of a styrene-butadiene rubber-containing component with respect to 100 parts by mass of the polymer component, and a styrene content in the styrene-butadiene rubber-containing component is less than 20 mass %.

Articles of footwear for protecting injured, at-risk, or post-surgical feet and ankles include upper and/or sole structures that offload the feet and ankles when standing and/or walking.

Electronic assistive gloves for covering artificial prosthetic or robotic hands. The glove includes a base layer formed to fit on the artificial hand, a plurality of sensors carried by the base layer, and an encapsulation layer covering the base layer and formed of a material that mimics human skin.

An additional chamber to watercraft that adds both volume and curvature to other compartments or components of the watercraft that are essentially flat is described. The additional chamber provides for modular construction of watercraft for creating volumetric space as well as a curved surface to the outer portion of the watercraft. The chamber advantageously increases the aesthetic appeal of the watercraft as well as provides a surface on which water is discouraged from pooling or collecting on. Various watercrafts having such a chamber are also described.

A non-black roofing membrane comprises an EPDM rubber; a non-black filler; a UV light stabilizer selected from the group consisting of NOR-HALS of the formula

##STR00001##

wherein R* is C.sub.1-C.sub.20alkyl, OH-substituted C.sub.1-C.sub.20alkyl, optionally C.sub.1-C.sub.4 alkyl-substituted C.sub.5-C.sub.12cycloalkyl, C.sub.7-C.sub.9phenylalkyl or O- or S-interrupted C.sub.2-C.sub.20alkyl, preferably C.sub.1-C.sub.12alkyl, benzyl or C.sub.5-C.sub.8 cycloalkyl especially C.sub.6-C.sub.10alkyl or cyclohexyl; and a cure package. The resultant roofing membrane provides increased weathering resistance.

A battery pack includes a battery housing and electrochemical cells disposed in the battery housing in a stacked configuration. Elastic members are disposed between adjacent cells of a cell stack. Each elastic member is a bladder that is formed of a pair of contoured plate portions stacked in a mirrored arrangement, whereby the plate portions cooperate to form a bellows-type compression spring. The elastic members provide a predetermined compression force to each cell while accommodating cell growth during use. The elastic members may include surface features such as strategically shaped and/or located protrusions that are configured to permit compliance and can be tuned to address the requirements of a specific application and permit application of varying stiffness characteristics across a surface of a cell.

A non-black roofing membrane comprises an EPDM rubber; a non-black filler; a UV light stabilizer selected from the group consisting of NOR-HALS of the formula ##STR00001##
wherein R* is C.sub.1-C.sub.20alkyl, OH-substituted C.sub.1-C.sub.20alkyl, optionally C.sub.1-C.sub.4 alkyl-substituted C.sub.5-C.sub.12cycloalkyl, C.sub.7-C.sub.9phenylalkyl or O- or S-interrupted C.sub.2-C.sub.20alkyl, preferably C.sub.1-C.sub.12alkyl, benzyl or C.sub.5-C.sub.8 cycloalkyl especially C.sub.6-C.sub.10alkyl or cyclohexyl; and a cure package. The resultant roofing membrane provides increased weathering resistance.

A composite material system having an aggregate bound by an elastomer encapsulant. The composite material (CM) is designed to defeat impinging projectiles by converting the kinetic energy (KE) in the projectile to damage in the aggregate and the elastomer and increasing the thermal energy in the CM and the projectile via frictional heating. In one embodiment, the CM comprises certain kinds of rocks encapsulated (or bound) in a hyper-elastic polymer, such as polyurethane (PU). The CM may be shaped into convenient shapes from modular assembly to create a ballistic resistant surface.

The present invention aims to provide a laminate including a fluororubber layer and an acrylic rubber layer which are firmly bonded to each other and are not separated even at high temperatures. The laminate of the present invention includes a fluororubber layer and an acrylic rubber layer. The fluororubber layer is formed from a fluororubber composition containing a fluororubber that contains a polyol-crosslinkable vinylidene fluoride unit, a polyol crosslinker, and a crosslinking accelerator. The crosslinking accelerator is a quaternary phosphonium salt free from a chlorine atom. The fluororubber has an acid value of 0.20 KOHmg/g or higher.

A roofing membrane comprising at least one layer of a cured rubber and expandable graphite dispersed within the cured rubber.
