Abstract

Es wird ein Werkstoff für elektrische Kontakte mit Licht­ bogenlöschung beschrieben, welcher aus einer irreversibel ausgehärteten Polymer-Formmasse (Duromer) besteht, welche mit 5 bis 20 Vol.-% eines Metallpulvers und wahlweise bis zu 40 Vol.-% eines weiteren anorganischen, elektrisch nicht leitenden Pulvers gefüllt ist.
Als Duromer wird ein solches verwendet, welches sich ohne Auftreten einer flüssigen Phase aushärten läßt.
