Abstract: The invention relates to a layered material, comprising a substrate and at least one layer A, wherein the at least one layer A comprises at least 50 wt % of a branched copolyester, wherein wt % is with respect to the total weight of layer A, and wherein the branched copolyester has a melting temperature of between 125° C. and 185° C., Mz/Mw of at least 3.5, and having a Melt Flow Index (MFI) of at most 10 g/10 min as measured at 190° C. with 2.16 kg. The invention also relates to a film comprising at least one layer A.

Abstract: The invention relates to an optical fiber cable element comprising a buffer tube and a number of optical fibers enveloped by the buffer tube, wherein the buffer tube comprises a semi-crystalline semi-aromatic polyamide comprising repeat units derived from monomers essentially consisting of dicarboxylic acid and diamine, comprising at least 55 mole % aromatic dicarboxylic acid, relative to the total molar amount of dicarboxylic acid, and having a glass transition temperature (Tg) of at least 100° C. The invention further relates to a process for producing the optical fiber cable element, and to an optical fiber cable construction, comprising a jacket and one or more optical fiber cable elements.

Abstract: Apparatus for dosing a urea solution to a selective catalytic reduction (SCR) catalyst in the exhaust of an internal combustion engine, the apparatus comprising an injector for injection of the solution in the exhaust and a tube (1) for transporting the solution to the injector, wherein a heating element (2) is in contact with the tube, which heating element is a Positive Temperature Coefficient (PTC) heating element, comprising at least two parallel wires (4.1, 4.2) embedded in a body (3) of a composition, which composition comprises a polymer and an electrically conductive filler.
