Potting compound, method for electrically isolating an electrical or electronic component and electrically insulated component

摘要

The invention relates to a casting compound. This contains 5.0 - 30.0% by weight of reactive particles, which are selected from magnesium oxide particles with a maximum particle size of 5.0 µm, porous magnesium oxide particle agglomerates, silicon oxide particles with a maximum particle size of 0.5 µm, silica particles with a maximum particle size 0.5 µm and mixtures thereof, 45.0 - 90.0% by weight filler particles with a particle size of more than 1 µm and / or filler fibers, and 5.0 - 20.0% by weight water. In a method for electrically isolating an electrical or electronic component, it is cast with the casting compound (11). Then it is heat-treated (12) at a temperature in the range from 50 ° C. to 95 ° C. in an atmosphere saturated with water, and dried. An electrically insulated component can be produced in this way.
