The invention provides an article comprising a first layer and a second layer, and wherein the first layer is formed from a first composition comprising an ethylene/-olefin/diene interpolymer, an isoprene rubber (synthetic), a natural rubber, a butadiene rubber, a styrene butadiene rubber, a chloroprene rubber, a nitrile rubber, a hydrogenated nitrile rubber, a chlorinated polyethylene, a chlorosulfonated polyethylene, an ethylene/propylene rubber, an ethylene/diene copolymer, a fluoro rubber, a polyurethane, a silicone rubber, or a combination thereof; and wherein the second layer is formed from a second composition comprising a butyl rubber, a halobutyl rubber, polyvinylidene chloride, a brominated polymer derived from a copolymer of isobutylene and p-methyl styrene, a nitrile rubber, a chloroprene rubber, a chlorosulfonated polyethylene, a chlorinated polyethylene, a polyurethane, a fluoro rubber, or a combination thereof.

A hot melt adhesive material and articles made using the hot melt adhesive to assemble structures in an article. The adhesive material typically is manufactured by blending amorphous polymer with a heterophase polymer having crystallinity into an adhesive composition.

The present invention relates to a method for manufacturing thin-film photovoltaic panels by the use of a sealing means composed by a polymeric tri-layer comprising a composite getter system composed of a polymer with a low H.sub.2O transmission, having dispersed in its inside a H.sub.2O sorption material, and two outer polymeric layers with the composite getter system therebetween, as well as to a polymeric tri-layer for the manufacturing of photovoltaic panels.

Provided is a retreaded tire that uses cushion rubber for retread that is able to further improve the prevention of separation failure while effectively suppressing blowout within the cushion rubber layer. The retreaded tire includes cushion rubber for retread, a base tire, and precured tread rubber formed of at least one rubber layer, and is characterized by: the aforementioned cushion rubber for retreaded tires being formed from a rubber composition containing specific quantities of a highly reinforcing carbon black of at least HAF grade, and natural rubber and/or synthetic polyisoprene rubber; the 100% modulus (A.sub.M) of the rubber layer (A) that comprises the aforementioned cushion rubber for retread being at least 3.0 MPa and less than 6.0 MPa; and the outermost layer (B) of the aforementioned base tire and the innermost layer (C) of the aforementioned precured tread rubber being formed from a rubber composition containing specific quantities of natural rubber and/or synthetic polyisoprene rubber.
