Polyetheretherketone (PEEK) has seen spectacular growth during the 90's and has reached a global consumption level of about 2000 tonnes. Due to the increasing acceptance of PEEK as a replacement of metals, particularly where very high temperature performance is desired, it is expected that PEEK will continue to grow at 20% in the next decade. The increased demand is driven by the semiconductor market where PEEK is used in several components of chip manufacturing systems. PEEK is expected to find increasing usage in newer energy saving products of heating, ventilation and compressors/generators. Infact, the stupendous growth of more than 40% observed in 2000 has resulted in global shortage. Victrex, the major suppliers of PEEK is unable to meet the increasing demand. Fortunately a new supplier of PEEK (Gharada Chemicals) from India has emerged. Victex as well as Gharada Chemicals are planning to increase their capacities to meet growing demand. The markets of some other Polyketone compounds derived from Polyaryletterketone (PAEK) are also growing particularly in the area of circuit board manufacturing. Polyketones due to their excellent fatigue resistance can find applications as orthopedic, cardiovascular and dental implants. This specialty engineering polymer definitely has a bright future.
