Techtron™ HPV FG PPS (Food Grade) is an internally lubricated, EU 10/2011 and FDA compliant PPS material that offers 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 FG PPS closes the gap in performance and price between standard thermoplastics and advanced engineering plastics. For this reason, this versatile grade is ideal 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.
