ABSTRACT:
An arc resistant composition is produced by incorporating into poly(arylene sulfide) about 30-70 percent by weight of fillers including 20-50 percent by weight of the total composition of at least one of clay and talc. Glass, calcium carbonate, lithium carbonate, and zinc stearate can also be present in the composition to improve physical properties and processing. Addition of small quantities of silanes to the arc resistant composition improves its water resistance and linear coefficient of expansion without impairing its arc resistance or physical properties. Electrical components which must be arc resistant and low wattage resistance heater housings can be produced from the compositions made in accordance with this invention.
