The filter comprises a filter housing () that can be separated along a separating plane () and the exchangeable filter insert () extending in an axial direction (). Two housing parts () of the filter housing () are sealed relative to one another along the separating plane () by means of a seal (). The seal () is secured slidably and captively in the axial direction () on the filter insert ().

Exchangeable filter insert

The present invention relates to a plastics molding composition based on polyarylene sulfide and/or on liquid-crystalline plastic, where the molding composition comprises carbon black and graphite and/or metal powder, the carbon black has a specific surface area of from 500 to 1500 m/g, and a dibutyl phthalate value of from 100 to 700 ml/100 g, and the graphite has a specific surface area of from 1 to 35 m/g. The molding compositions of the invention have good conductivities, and better flowabilities and mechanical properties.
