ABSTRACT:
A composition is provided containing a poly(arylene sulfide) and a hydrotalcite. The composition can further contain glass fibers and is suitable as a molding composition. The hydrotalcite-containing poly(arylene sulfide) provides a molding composition which offers the combination of mold corrosion inhibition, hydrolytic stability and insulation resistance compared with prior molding compositions. Also provided is an article of manufacture comprising a hydrotalcite-containing poly(arylene sulfide) molded part in contact with a liquid electrolyte. The use of hydrotalcite-containing resin reduces the effect of corrosive ionic species extractable from the poly(arylene sulfide) by the electrolyte. Such an article of manufacture would include, for example, a capacitor having a liquid electrolyte and a poly(arylene sulfide) cover.
