A non-crosslinked rubber laminate which is a rubber laminate includes a butyl rubber-containing layer stacked with an ethylene propylene diene rubber and/or ethylene propylene rubber-containing layer, wherein such non-crosslinked rubber laminate is characterized in that the ethylene propylene diene rubber and/or ethylene propylene rubber-containing layer is a rubber-containing layer that contains a low-molecular-weight polyolefin, a phenolic resin, and a crosslinking agent, where: the low-molecular-weight polyolefin is contained by 40 to 70 parts by weight, the phenolic resin is contained by 1 to 4 parts by weight, and the crosslinking agent is contained by at least 1 part by weight, relative to the ethylene propylene diene rubber and/or ethylene propylene rubber constituting a total of 100 parts by weight. An air conditioning hose made of the rubber laminate, for example, can accommodate POE-based lubricating oils and retain vibration absorption characteristics.

Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.

Provided is an organ model having a property such that each layer suitably peels off, a property such that sliding or a sense of catching is present besides a sense of elasticity that is felt when a surgical knife cuts the organ model open, and a property such that ligation can be performed without burying of a suture thread, and a property such that a knot of the thread gets caught on the organ model. An organ model being a laminated body in which plural layers each formed of a hydrogel material are laminated, and one or more of the layers is each a fiber group-containing layer in which fiber groups are approximately continuously present inside the layer and over the plane of the layer.

A laminate of different kinds of halogen-containing rubbers (polymers) excellent in bonding strength. The laminate including the following layers (1) and (2) directly bonded to each other: layer (1): a layer of a composition including 100 parts by mass of a halogen-based rubber (A) (excluding a fluorine-based rubber), and 1 to 30 parts by mass of an inorganic compound (B) containing at least one element selected from Group 2 elements and Group 13 elements, and an oxygen atom; and layer (2): a layer of a halogen-containing polymer (C) (excluding the halogen-based rubber of the layer (1)).

An article formed in a co-extrusion process comprises a base layer and a first cap layer disposed on the base layer. The base layer is formed from a thermoplastic olefin comprising a thermoplastic polymer, an elastomer, and a base filler. The base layer comprises greater than 15% by weight of the base filler. The first cap layer comprises at least one polyolefin and between 0-15% by weight of a first cap filler. The first cap layer has a thickness less than a thickness of the base layer. The first cap layer is configured to provide an exterior surface of the article resistant to whitening or fading caused by exposure to the ambient environment in comparison to the underlying base layer.

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.

An object of the present invention is to provide a laminate of an olefin-type rubber, which is non-polar or has a small polarity and which is difficult to bond with a different material, and a rubber including Group 16 elements and/or Group 17 elements, which is a different kind of rubber. The laminate according to the present invention includes a structure including, in order, an olefin-type rubber layer (A) ; an adhesive resin layer (B) containing at least one selected from the group consisting of an ethylene/vinyl acetate copolymer, a silane-modified ethylene/vinyl acetate copolymer, an ethylene/acrylic acid copolymer and an ionomer thereof, and an ethylene/methacrylic acid copolymer and an ionomer thereof; and a rubber layer (C) containing Group 16 elements and/or Group 17 elements.

Provided is a stretchable film that can prevent a delivery failure when delivered from a winding body. Also provided is a stretchable laminate including such stretchable film. Still also provided is an article including such stretchable laminate. The stretchable film of the present invention includes a laminated film of a plurality of elastomer layers, wherein the stretchable film includes an elastomer layer (A1), an elastomer layer (B), and an elastomer layer (A2) in the stated order, wherein the elastomer layer (A1) and the elastomer layer (A2) are provided as outer layers, and wherein each of the elastomer layer (A1) and the elastomer layer (A2) contains a fatty acid amide.

An elastomeric laminate is provided. The elastomeric laminate comprises a layer A consisting of a diene rubber composition, a layer B comprising a highly unsaturated diene elastomer B, n layers Ci arranged between the layer A and the layer B, n being an integer 2, i being an integer ranging from 1 to n, the layer C1 being arranged between the layer A and the layer C2, the layer Cn being arranged between the layer B and the layer Cn1, the layer Ci being arranged between the layer Ci1 and the layer Ci+1 for values of i ranging from 2 to n1 when n>2. Such a laminate has good resistance to separation of the layers which constitute it.

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.
