A method includes using a sealing element to dynamically seal a sealing body in the presence of a lubricant. The sealing element has an elastomeric base body and a plasma coating. The coating includes the elements carbon, oxygen, silicon, and hydrogen. The coating has the following properties at least at the surface: the amount ratio C:Si (at %/at %) is &#x3e;5, the amount ratio O:Si (at %/at %) is &#x3e;3, and the surface energy is &#x3c;50 mN/m. In an embodiment, the coating includes the element fluorine.

Plasma-coated sealing element

An elastomeric body for vibration damping and/or suspension, has a base body and a flame-retarding coating which covers at least one section of the base body, wherein the flame-retarding coating has at least two intumescent fire protection systems and the first fire protection system contains expandable graphite which comprises at least a first fraction with an average grain size of more than 180 &#x3bc;m and at least a second fraction with an average grain size of less than 180 &#x3bc;m, and the second fire protection system forms a support structure in the expanded state, which structure at least partially fixes the expanded graphite in the expanded state.
