Abstract: A thermoplastic composition includes: (a) from about 20 wt % to about 80 wt % of a first thermoplastic polymer including aliphatic polyamide (PA), polyphthalamide (PPA), copolymers thereof, or a combination thereof; (b) from about 0.1 wt % to about 1.5 wt % of a second thermoplastic polymer including polybutylene terephthalate (PBT), poly1,4-cyclohexylene dimethylene terephthalate (PCT), polycarbonate (PC), copolymers thereof, or a combination thereof; and (c) from about 10 wt % to about 60 wt % of a filler component. The composition has a melt volume rate (MVR) as measured in accordance with ASTM D1238 that is at least about 10% higher than that of a substantially identical reference thermoplastic composition that does not include the second thermoplastic polymer, or has a melt viscosity (MV) as measured in accordance with ISO11443 that is at least 20% lower than that of a substantially identical reference thermoplastic composition that does not include the second thermoplastic polymer.

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−1, 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).
