Electrical insulating material and method for preparing insulating material element

A method for preparing an electrical insulating element with an electrical insulating material, comprising:

• a) providing the electrical insulating material, comprising a matrix component, a filler component and a liquid hydrophobic component;
• wherein the matrix component comprises a saturated styrenic block copolymer;
• b) mixing each component of the electrical insulating material in any desired sequence to get a mixture;
• c) putting the mixture from step b) into a Brabender mixer or extruder to be blended in a molten state;
• d) cutting the mixture from step c) into pellets;
• and
• e) putting the pellets from step d) into an injection moulding machine to produce a desired shape of the electrical insulating element.
