Raw Materials Property

PEEK (polyether ether ketone) is a new type of semi-crystalline aromatic thermoplastic engineering plastics, which was successfully developed by Imperial Chemical (ICI) in the late 1970s. The material possesses high levels of heat, radiation and corrosion resistance, as well as excellent dimensional stability and electrical properties, and outstanding processability, among many other advantages. As a result, PEEK is recognized as one of the world's highest-performance thermoplastic materials and is widely used in the defense and military industries, the aerospace industry, the electronics and information industry, energy development, processing and utilization, automotive manufacturing, home appliance production, and medical and health care."
