摘要： The present invention relates to a multilayer tube comprising, in its radial direction from the outside inwards: an outer layer formed from a polyamide, a layer formed from a copolyamide, a layer formed from an EVOH, a layer formed from a copolyamide, an inner layer formed from a polyamide, the layers being successive and adhering to one another in their respective contact region. Advantageously, the inner layer is formed by a compound based on a polyamide and electrically conducting carbon black, producing a surface resistivity of less than 106 null/null. The outside diameter of these tubes may range from 6 to 110 mm and the wall thickness may be from 0.5 to 5 mm. Advantageously, the petrol tube according to the invention has an outside diameter ranging from 6 to 12 mm and a total wall thickness of 0.36 mm to 1.95 mm, namely: a thickness of 50 to 700 nullm for the polyamide outer layer, a thickness of 10 to 150 nullm for the copolyamide layers, a thickness of 10 to 200 nullm for the EVOH layer, a thickness of 100 to 500 nullm for the polyamide inner layer possibly filled with electrically conducting carbon black. The tube of the present invention has a very low permeability to petrol, particularly to hydrocarbons and their additives, and in particular to alcohols, such as methanol and ethanol, or to ethers, such as MTBE or ETBE. These tubes also have good resistance to engine lubrication oils and fuels.

摘要： The present invention relates to a microcomposite powder comprising particles from 1 um to 300 um of an electrically conductive product, which are coated with particles from 0.1 nullm to 0.5 nullm of a fluoropolymer. According to one advantageous form of the invention the microcomposite powder comprises a product (A) which is a polymer or an oligomer which can be dissolved with a solvent which is not a solvent for the fluoropolymer or for the electrically conductive product. The present invention also relates to objects consisting of this powder. These objects may be bipolar plates for fuel cells, or supercapacitor components.

摘要： A composition coextrudable with PVDF comprises in parts by weight: 20 to 40 parts of PVDF; 40 to 60 parts of PMMA; 5 to 18 parts of an acrylic elastomer; 1 to 4 parts of a UV absorber; the total making 100 parts. Coextruded films comprise a layer of the above coextrudable composition directly attached to the latter; and a PVDF-based layer comprising, as main constituents, 50 to 100 parts of PVDF per 50 to 0 parts of PMMA respectively. The PVDF layer may be in the form of two layers: one placed against the coextrudable layer and comprising, as main constituents, 50 to 90 parts of PVDF per 50 to 10 parts of PMMA respectively; and the other (also called the outer layer) comprising, as main constituents, 75 to 100 parts of PVDF per 25 to 0 parts of PMMA respectively. The resultant products are generally applied to substrates, e.g. as protective films.
