Techtron™ PSGF PPS shapes are compression-molded and glass-filled, giving them extreme dimensional stability as well as improved chemical and corrosion resistance over unfilled polyphenylene sulfide materials. Due to these improved performance characteristics, Techtron™ PSGF PPS is often chosen as a solution for applications involving critical sealing and structural components, such as pump housings, valves and compressors within the oil and gas industry.
