Many automotive, underhood aplications stimulate high interest for replacement of metals by reinforced plastics. Plastic parts offer greater design flexibility, manufacturing cost savings, weight reduction, and noise reduction than their metal counterparts. PPS has been used for many years in automotive applications. Ryton PPS is highly suited for underhood applications exposed to high temperaturs and corrosive fluids such as engine coolant, motor oil, gasolines, and brake fluid. However, many underhood applications such as fuel rails and intake manifolds canot be easily manufactured by injection molding. A new PPS compound has been developed for blow molding. This material will provide the designer with a material having high thermal and chemical stability, and the flexibility that blow molding offers. This paper will discuss three major points for this unique use of Ryton PPS: the material properties of blow molded Ryton PPS, including impact strength and heat deflection temperature; the grater design flexiblity offered with blow molding versus injection molding; and the processing parameters required for the successful blow molding of Ryton PPS.
