1. An article manufactured by molding a composite, the composite comprising:
(A) a polymer matrix; and
(B) (i) a inorganic moisture absorber, (ii) a ceramic filler, graphite, or a combination thereof, and (iii) a tracking resistance polymer, which are dispersed in the polymer matrix,
wherein the polymer matrix comprises a liquid crystal polymer, wherein the liquid crystal polymer is present in an amount of greater than or equal to 30 weight percent to less than 80 weight percent based on a total weight of the composite;
wherein the inorganic moisture absorber is present in an amount of greater than or equal to 1 weight percent to less than or equal to 20 weight percent, based on a total weight of the composite;
wherein the ceramic filler, the graphite, or the combination thereof is present in an amount of greater than or equal to 1 weight percent to less than or equal to 20 weight percent, based on a total weight of the composite; and
wherein the tracking resistance polymer is present in an amount of greater than or equal to 10 weight percent to less than or equal to 35 weight percent based on a total weight of the composite,
wherein the tracking resistance polymer comprises:
an average bond energy between an atom forming a main chain in the tracking resistance polymer and another atom covalently bonded to the atom that forms the main chain in the tracking resistance polymer of about 350 kilojoules per mole to about 500 kilojoules per mole,
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,
wherein the article is a container comprising a bottom wall, a plurality of side walls, and an open side opposed to the bottom wall, and
wherein at least one of the bottom wall and the plurality of side walls comprises the composite, and the composite defines inner and outer surfaces of the at least one of the bottom wall and the plurality of side walls.
 
11. The article of claim 1, wherein the composite comprises the tracking resistance polymer in an amount of greater than or equal to 10 weight percent to less than or equal to 30 weight percent, based on a total weight of the composite.
