A method for producing a vehicle tire, having the following steps: a) providing textile reinforcing supports; b) providing a bath which is free of resorcin and formaldehyde by at least: b1) adding at least one carboxylic acid to water; b2) adding at least one base; b3) adding at least one epoxy compound; b4) adding at least one polyisocyanate compound; b5) adding at least one VP latex; and b6) mixing the substances from b1) to b5); c) dipping the reinforcing supports from step a) into the bath from step b); d) subsequently hot-stretching the dipped reinforcing supports from step c); and e) further processing the reinforcing supports from step d) in order to form a reinforcing support layer in a vehicle tire blank. A vehicle tire which is produced using the method and to the use of reinforcing supports treated in such a manner in technical rubber articles are also disclosed.

The present disclosure is drawn to covers for electronic devices, coating sets for covers of electronic devices, and methods for making these covers. In one example, described herein is a cover for an electronic device comprising: a substrate; an adhesive layer on a surface of the substrate; a first thermally conductive layer on the adhesive layer; a first oxide layer on the first thermally conductive layer; an aluminum foil layer on the first oxide layer; a second oxide layer on the aluminum foil layer; and a second thermally conductive layer on the second oxide layer.

The invention relates to an article having a single- or multi-layered main body having elastic properties, in particular an air spring bellows, a metal-rubber element or a vibration damper.

In order to improve its flame retardant properties, the main body of the article consists of or contains at least one layer D constructed from a rubber mixture which is free from halogen-containing flame retardants and contains at least one carbon black having a BET surface area according to DIN-ISO 9277 between 35 and 140 m.sup.2/g and an oil absorption number (OAN) according to ISO 4656 between 70 and 140 ml/100 g and a first aluminum trihydrate (ATH_1) and at least a further aluminum trihydrate (ATH_2), wherein the first aluminum trihydrate (ATH_1) and the further aluminum trihydrate (ATH_2) each have a different particle size.
