The invention relates to an article comprising a single or multi-layer main body having elastic properties, in particular air spring bellows, a metal-rubber element or a vibration damper. In order to improve the flame-retarding properties, the main body of the article consists of or contains at least one layer D formed of a rubber mixture that is free from halogen-containing flame retardant means and contains at least one carbon black with a BET surface area of between 35 and 140 m2/g (according to DIN-ISO 9277) and with an oil absorption number (OAN) of between 70 and 140 ml /100g (according to ISO 4656), and a first aluminium trihydrate (ATH_1) and at least one further aluminium trihydrate (ATH_2), wherein the first aluminium trihydrate (ATH_1) and the further aluminium trihydrate (ATH_2) each have a different particle size. |
