  • Insulating liquids and electric cables
    Patent number: 4967039
    Abstract: A silicone base oil for use as impregnant in an electric power cable for fire hazard conditions is rendered non-gassing by the addition of about 2-8% of an aryl alkane having at least two benzene rings spaced apart by not less than one nor more than two aliphatic carbon atoms. The total number of aliphatic carbon atoms in the molecule is limited to six, and the silicone oil should be chosen with a sufficiently high flashpoint for the whole oil to have flashpoint above 150.degree.C. The preferred additive is 1-phenyl 1-(3,4 dimethylphenyl) ethane, also known as PXE.
