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/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.

The invention relates to a hose having at least one barrier layer inner layer and an outer layer, wherein the barrier layer is obtainable by extrusion of a mixture comprising a) at least one thermoplastic fluoropolymer, b) at least one fluororubber and a crosslinking agent and/or at least one fluororubber elastomer and c) at least one carbon filler selected from carbon black, in particular conductivity carbon black, graphene, carbon nanofillers, in particular carbon nanotubes, carbon nanohorns, or a combination thereof in an amount of 0.05% by weight to 20% by weight of the carbon filler(s), or irradiated PTFE, and vulcanization. The hose exhibits a high fuel, diesel and oil stability and dynamic capability.

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 a first aluminum trihydrate (ATH_1) and at least one further aluminum trihydrate (ATH_2) and at least one amorphous silicic acid having spherical particle geometry, wherein the first aluminum trihydrate (ATH_1) and the further aluminum trihydrate (ATH_2) each have a different particle size.

The disclosure relates to a rubber mixture which contains at least one fluorine rubber and at least one active filler and carbon nanotubes. The rubber mixture has an additionally improved tear propagation resistance and, at the same time, improved processability. The disclosure further relates to a hose having at least the following layer structure: an inner layer as a barrier layer against aggressive media, which contains at least one fluorine rubber and at least one active filler and carbon nanotubes; and, an outer layer made of a cross-linked rubber mixture.

The invention relates to a sensor as a built-in component of an object, especially an elastic object, the sensor comprising a polymer material containing electroconductive additives according to the invention and thereby acting as an expansion sensor (), in that it measures the static and dynamic expansions of the object in relation to the acting forces and also monitors the changes of the polymer material generated by the static and dynamic expansions of the object over time. The invention also relates to a sensor arrangement () acting especially in combination with the following components: an expansion sensor (), a fixed resistor (), an analog/digital converter (), a micro-controller comprising a memory (), a radio interface (), a controlled current/voltage source (), an energy supply (), a coupling coil (), and a receiving unit ().
