Abstract

Cross-linking and/or sintering of plastics and/or rubber is brought about by dielectric heating of the material mixed with polarised additives. Ferroelectrics or ferrites with high losses in the microwave field are used as additives and the mixt. exposed to the action of an electrical reversing field. The process is suitable for light-coloured materials, complete vulcanisation occurs without burning.
