Features: Very high-wear resistance, seven times wear resistance than steel, four times than PTFE. Very high-in adhesion resistance, the surface of product hardly affixes other material. Mostly using of its high-wear resistance, high anti-impact resistance, anti-cold resistance, self-lubrication, electric characteristic. Good low temperature resistance, in liquefied nitrogen (- 196), it still has the prolongation. Good anti-corrosion resistance, it has very stable chemicals property and can endure the corrosion of all kinds of corrosive medium and organic solvent in certain rang of temperature and humidity.
