A tube or a hose including a fluoroelastomer and a polytetrafluoroethylene, the tube or the hose being an extruded article. The polytetrafluoroethylene is dispersed in a state of single particles in the extruded article, or the polytetrafluoroethylene has a specific surface area of less than 8 m/g. Also disclosed is an extruded laminate including a fluoroelastomer layer formed form the tube or hose and a polymer layer.

Layered body and extrusion-molded article

Provided is a laminate comprising a fluoroelastomer layer and a polymer layer, wherein the fluoroelastomer layer is formed of a fluoroelastomer composition containing a fluoroelastomer, a basic polyfunctional compound, and a polytetrafluoroethylene, and the polytetrafluoroethylene is dispersed in a state of single particles in the fluoroelastomer layer.

The present invention has an object of providing a laminate which is composed of a layer containing a melt shapable fluororesin and a layer of an ethylene-α-olefin-nonconjugated polyene copolymer composition, and is excellent in adhesiveness, and the present invention relates to a laminate including: a layer including an ethylene-α-olefin-nonconjugated polyene copolymer composition, and a layer comprising a melt shapable fluororesin; wherein the ethylene-α-olefin-nonconjugated polyene copolymer composition includes 100 parts by mass of an ethylene-α-olefin-nonconjugated polyene copolymer (A), 1.0 to 6.0 parts by mass of at least one compound (C) selected from the group consisting of 1,8-diazabicyclo(5.4.0)undecene-7 salts, 1,5-diazabicyclo(4.3.0)nonene-5 salts, 1,8-diazabicyclo(5.4.0)undecene-7 and 1,5-diazabicyclo(4.3.0)nonene-5, and 3 to 20 parts by mass of magnesium oxide.

Laminate including layer of ethylene-α-olefin-nonconjugated polyene copolymer composition, and application thereof

The invention provides a laminate including a fluoroelastomer layer and a fluororesin layer which are firmly bonded to each other. The laminate includes a fluoroelastomer layer (A) and a fluororesin layer (B) stacked on the fluoroelastomer layer (A). The fluoroelastomer layer (A) is a layer formed from a fluoroelastomer composition. The fluoroelastomer composition contains a fluoroelastomer, a basic multifunctional compound, and at least one compound (a) selected from the group consisting of a fluororesin (a1) and a phosphorus compound (a2). The compound (a) is present in an amount of 0.01 to 120 parts by mass relative to 100 parts by mass of the fluoroelastomer. The fluororesin layer (B) is formed from a fluororesin (b1) having a fuel permeability coefficient of 2.0 g&#xb7;mm/m/day or lower.
