Abstract:
1. A method for injection molding a thermoplastic composition, the method comprising: injecting a thermoplastic composition into a mold cavity, wherein the thermoplastic composition comprises a polyarylene sulfide, boron nitride, aromatic amide oligomer, glass fibers, and a filler that includes a mineral filler, alksoxysilane coupling agent, or a combination thereof, wherein the weight ratio of aromatic amide oligomers to boron nitride in the composition is from about 1 to about 10, and further wherein boron nitride constitutes from about 0.05 wt. % to about 3 wt. % of the composition; cooling the thermoplastic composition within the mold cavity at a mold temperature of from about 50° C. to about 120° C.; and ejecting the molded part from the mold cavity wherein the composition has a crystallization potential of about 55% or more, as determined by differential scanning calorimetry in accordance with ISO 10350.
