Abstract
An electrical insulating material having anti-tracking properties has incorporated therein an erosion inhibiting fluorine-substituted compound. The electrical insulating material comprises a polymeric material having an anti-tracking filler and the fluorine-substituted compound is a hydrophobic, non-ionic compound having a fluorine-substituted aliphatic carbon chain linked to a group having an affinity for the polymeric material and/or the anti-tracking filler. The electrical insulating material may be used in high voltage applications where it is necessary to resist erosion and/or control leakage currents.
