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. It becomes a material for electrical contacts with light arc extinguishing described, which is an irreversible cured polymer molding compound (Duromer), which with 5 to 20 vol .-% of a metal powder and optionally up to 40 vol .-% of another inorganic, electrical non-conductive powder is filled.

Als Duromer wird ein solches verwendet, welches sich ohne Auftreten einer flüssigen Phase aushärten läßt. One is used as a duromer, which is can harden without the appearance of a liquid phase.
