Process for producing flexible, fibre-based, impregnated, protective, auxiliary and insulating materials for electrical purposes, by applying impregnating agent to the material to be impregnated, followed by curing, characterized in that a solvent-free impregnating material containing one or more olefinically unsaturated, radically polymerizable polyesters, one or more radically polymerizable monomers as reactive thinners, one or more plasticizers and possibly one or more peroxide-free radical initiators is applied and then cured by high-energy radiation and, if necessary, further cured by heating. |
