Need a custom plastic part that requires good temperature stability, broad chemical resistance, high strength, stiffness, and creep resistance at elevated temperatures? Polyphenylene sulfide (PPS) may be the solution. Aline Components, a reputable plastic injection molding and manufacturing company, offers PPS plastic along with a variety of other thermoplastic materials that perform to the highest level in diverse industrial- and consumer-based applications.
At Aline Components, we feature two distinct PPS compounds: Ryton® which is manufactured by the Phillips Chemical Co. and Fortron® which is manufactured by Ticona Engineering Polymers. Obtaining the right grade for your application is easy as we work directly with leading resin suppliers. Through this working relationship Aline is able to ensure quality thermoplastics at an exceptional value.
PPS is a semi-crystalline, high-performance thermoplastic engineering resin. Due to its inherent brittleness, PPS must be reinforced with glass or carbon fibers and fillers. Various fillers and reinforcements make a difference in strength, surface properties, dimensional stability, electrical properties and overall cost. Because flame retardance is inherent in PPS, recycled materials are as flame resistant as the original version.
PPS performs well in consistent elevated temperature conditions at approximately 230°C. In short-term durations, PPS exhibits heat deflection temperatures of 500°C or higher. Other properties include low temperature endurance, good chemical resistance, and flame retardance. Mechanical properties of PPS can be tailored for specific applications. The right formulation is achieved by altering the degree of crystallinity in the custom molded part or component.
Glass-fiber grades are recommended for mechanical electronic applications that require high mechanical strength, insulating characteristics, and impact resistance. For electrical applications that require high arc resistance and low arc tracking, grades that contain mineral fillers and glass-fiber reinforcements are suitable. Even in prolonged exposure to high temperatures, PPS is resistant to a broad variety of chemicals.
While traditional PPS has a partially cross-linked molecular structure, Fortron® possess a non-cross linked linear structure which enables it to overcome the inherent brittleness of PPS. Known for its high temperature performance, dimensional stability, excellent chemical and solvent resistance, and inherent flame resistance, Fortron® is available in many specialty grades for enhanced lubricity, low warpage, faster processing, and other areas of improved performance. Out of all advanced engineering thermoplastic resins, Ryton® PPS exhibits the broadest resistance to chemicals. Recognized as the world’s premier product for demanding plastic parts automotive, electrical, appliance, and industrial applications, Ryton® has very low moisture absorption, maintains its strength to above 425°, and is available in two grades; bearing and glass reinforced.
