Ticona Engineering Polymers has developed a new grade of Fortron that it claims is the first polyphenylene sulfide (PPS) designed for use with 3-D robotic manipulated blow molding for tubular components with extreme complex geometries. With the introduction of this developmental Fortron PPS grade, customers can now use all available blow molding technologies—standard, 3-D suction, robot manipulation and injection—to create air inlet systems and EGR pipes with multiple bends while reducing the number of manufacturing steps and shortening cycle times. The new Fortron PPS grade, which passed all high temperature tests in a production scale trial, offers a set of material properties beyond those of standard blow-moldable Fortron PPS grades: higher melt strength, improved impact resistance, higher blow up ratio, longer handling time, and no restriction regarding vibration. Ticona is working with Röchling Automotive on a new air duct geometry that requires Fortron PPS. While initially used in an automotive application, Fortron PPS can be used in other industries that use extrusion, thermal forming, and blow molding technologies.
