ABSTRACT:
A process for free sintering parts made from mixtures of poly(phenylene sulfide) and at least one selected filler by subjecting molded parts to gradually increasing temperatures and then curing at an elevated temperature. Precured poly(phenylene sulfide) is first mixed with the selected filler and then compression molded to form a part of a desired shape. The part is then free sintered by being subjected to a gradually increasing temperature in an oven and cured. After curing, the part is cooled and is ready for use.
