anti-corrosion ,self- lubrication ,good electrical property, resistence of abrasion,heat, high energy radiation,chemical and hydrolysis,low weight and low voice,stable mechanical performance,excellent wear and friction behaviour,good dimentional stability, high machanical strenghth ,stiffness and creep resistence, also at elevated temperatures. Low flammability and very low levels of smoke evolution during combustion,low moisture absorption.allowable service temprature in air (250a?? continuously,up to 310a?? for short periods)

widely used in dying and pringting machinery
