ABSTRACT:
Polyamide molding compositions comprising a polyamide resin, about 5 to 40 percent by weight, based on the total weight of the compositions, of talc in the form of platy fine particles having a surface are of about at least about 7.sup.2 m /g; about 2 to 40 percent by weight, based on the total weight of the composition, of wollastonite; and about 5 to 25 percent by weight, based on the total weight of the composition, of fiber glass. Preferably, about 0.1 to 4 weight percent, based on the weight of the wollastonite, of a coupling agent is present. These molding compositions are capable of providing molded articles having a creep slope of .ltoreq.0.15 percent strain per log time.
