Techtron™ HPV PPS shapes offer superior wear resistance, outstanding chemical and hydrolysis resistance, excellent dimensional stability, great electrical insulating and dielectric properties, a low coefficient of friction and inherently low flammability. As a reinforced, internal lubricant-filled grade, Techtron™ HPV PPS closes the gap in performance and price, between standard thermoplastics and advanced engineering plastics. For this reason, this versatile grade of polyphenylene sulfide is great for wear components such as bushings and bearings, CIP wash down parts and pump, valve and compressor applications throughout the aerospace, food processing and oil and gas industries.
