Abstract
A composite including a polymer matrix; an inorganic moisture absorber; a ceramic filler, graphite, or a combination thereof; and a tracking resistance polymer, wherein the tracking resistance polymer includes an average bond energy between an atom forming a main chain and another atom covalently bonded to the atom that forms the main chain of about 350 kJ/mol to about 500 kJ/mol; a carbonaceous residue yield after pyrolysis of less than or equal to about 5 weight percent, based on the amount of the tracking resistance polymer before pyrolysis; or a combination thereof.
