Techtron™ PSBG PPS compression-molded shapes are internally lubricated and carbon fiber-reinforced, allowing them to exhibit excellent wear resistance, outstanding dimensional stability and extreme chemical and corrosion resistance. This grade in particular possesses the lowest coefficient of linear thermal expansion of all Techtron™ PPS Grades, allowing it to excel in wear applications where an electrically conductive material is required. Other application examples include bushings and bearings, lantern rings and pump wear components throughout the oil and gas industry.
