Abstract
The invention relates to an article having a main body with elastic characteristics, in particular an air spring bellows, a metal-rubber element or a vibration damper. The article has a single-layer or multilayer main body having elastic properties, wherein the outer layer C has at least two laminas C/Cand each lamina is formed from an elastomer mixture, and wherein at least one layer D composed of a weave or loop-formed knit or loop-drawn knit has been embedded into this outer layer. This leads to further optimization of the fire-retardant properties.
