Abstract
A reinforced poly(phthalamide) composition comprising 20-80 weight percent of a poly(phthalamide) component comprising 15-55 weight percent of a crystalline poly(phthalamide), and 5-45 weight percent of an amorphous poly(phthalamide); 0.5-60 weight percent of a reinforcing filler; and 0.1-50 weight percent of an additive composition; wherein weight percent is based on the total weight of the reinforced poly(phthalamide) composition and totals 100; and wherein the reinforced poly(phthalamide) composition has a capillary melt viscosity, measured according to ASTM D3835 (2015) at 320° C., at 5000 s, that is at least 10% lower than that of the same reinforced poly(phthalamide) composition without the amorphous poly(phthalamide), and a warpage that is at least 15% lower than that of the same reinforced poly(phthalamide) composition without the amorphous poly(phthalamide).
