摘要:
A hydrogenated nitrile rubber-metal laminate, which comprises a metallic sheet subjected to a hexavalent Cr ions-free chemical conversion treatment, a defatting treatment, a surface-roughening treatment, a primer treatment, or a combination of the treatment, and an adhesive layer and a rubber layer successively laid on one or both surfaces of the metallic sheet, wherein the rubber layer is a vulcanizate of a hydrogenated nitrile rubber compound comprising 100 parts by weight of a hydrogenated nitrile rubber, 50-250 parts by weight of an inorganic filler containing not more than 20% by volume, on the basis of total compound, of a non-reinforcing inorganic filler having an average particle size of not more than 5 µ m, 4-20 parts by weight of an organic peroxide, and preferably furthermore 2-10 parts by weight of N,N' -phenylene dimaleimide. The rubber-metal laminate has a vulcanized rubber layer(s) distinguished in the heat resistant at elevated temperatures of 150°C or higher, the heat bending resistance, e.g. at 200°C for 100 hours, and the rubber bulging resistance (rubber flow resistance) when used at elevated temperatures and surface pressures.

The present invention describes a backsheet (10) for electronic devices comprising at least a heat resistant layer (12c) reactive and attached with a PolyOlefine based tie-layer(s) (12b) provided at the side facing the active material (4) to be encapsulated. Optionally further layer(s) (12a) are provided on top of layer (12b), being Flexible PolyPropylene and/or (co-)PE based layer(s). Optionally a last layer (13b) is provided facing the active material (4) based on (co-)PE based tie-layer (13b), such layer providing good adhesion directly on the back-side of the active material (4), or attached barrier layers.

A composite having (a) a substrate that has opposing first and second surfaces, the substrate being at least 90% transmissive in visible light and has less than 5% haze, (b) a nanostructured article including a matrix and a nanoscale dispersed phase and having a random nanostructured anisotropic surface; and (c) an optically clear adhesive disposed on the second surface of the substrate.
摘要:
The present invention provides a separator including a separator substrate composed of a polylactic acid film or sheet having tear strength so as not to break or tear during, for example, production or processing of the separator or winding thereof into a roll, and causing neither melt nor deformation at high temperatures more than 100°C. The separator according to the present invention is a separator including a separator substrate and a removable pressure-sensitive adhesive layer on at least one surface of the separator substrate, wherein the separator substrate is composed of a polylactic acid film or sheet comprising polylactic acid (A) wherein the tear strength of the film or sheet is not less than 100 N/mm when the film or sheet is torn at least in a flow direction (MD), a rate of dimensional change due to heating is not more than ±3% in the flow direction (MD) and a transverse direction (TD), and a rate of dimensional change due to loaded heating is not more than ±3% in the flow direction (MD).
