ABSTRACT:
An improved method for the production of an extrudate of poly(phenylene sulfide) and filler with the resulting extrudate having a stiffness of less than 10,000 psi as determined by ASTM D747-70. The extrudate formed is very flexible. The method includes the step of applying pressure to a heated mixture of poly(phenylene sulfide) and filler and flowing the mixture through a first orifice into an expansion chamber and out of the expansion chamber through a second orifice. The extrudate exiting the second orifice is extruded into the atmosphere or into a mold cavity for the molding of a piece part. The resulting extrudate is flexible and can be used as a packing or gasket material.
