PEEK(Polyetheretherketone) offers excellent mechanical properties compared with other special engineering plastics. PEEK materials has a superior wear resistance and dimensional stability to 480°F continuous use and excellent resistance to chemicals, steam and hydrolysis used in petroleum/natural gas/ultra-pure water transportation and storage equipment such as pipelines, valves, pumps and volumeters. In addition, It  is often used to manufacture deflector valves, piston rings, seals and various chemical pump and valve components. In the ball valve for oil and gas, PEEK is mainly used as sealing materials like seats and seat inserts, stem packings, high-performance spring energized body seat and stem seals.
