More Information
Summary: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 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 15% 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 ISO 11443 that is at least 15% lower than that of a substantially identical reference thermoplastic composition that does not include the second thermoplastic polymer.
