...China, with a 1,000t/a production plant in Northern China [2]. It has a product portfolio of unfilled grades in three melt viscosities and compounds with glass and carbon fibers as well as a lubricated grade sold under the trade name Vestakeep. A slightly different polymer, PEKK (polyetherketoneketone), is supplied by US-based Oxford Performance Materials under the trade name Oxpekk. Their focus is to generate additional biomedical applications [3], a market niche first established by Victrex’s ...

.... Evonik added PEEK to its portfolio of high-end polymers by forming JIDA Degussa High Performance Polymers, a joint venture, in 2005. These products have since been renamed and have been marketed by Evonik Industries AG worldwide under the name Vestakeep since September 2007. The product range is broadly similar to that of Victrex: it comprises PEEK in four melt viscosities, unreinforced, reinforced with glass fiber or carbon fiber, and tribological grades as granulate for extrusion and injecti...

...matrix and then the mechanical/technical properties of the composite, as well as cytotoxicity and cell growth behavior are comprehensively tested. Among the materials being produced are composites made from PEEK high-performance plastic (grade: Vestakeep 2000P) and 5–50 wt.-% TiO2 filler (grade:Aeroxide P25, a powder with nanoscale primary particle size). Both materials are supplied by Evonik Degussa GmbH. Through the combination of a thermoplastic and bioactive filler, the advantages of the two...

...acemakers, battery insulator must be precisely tailored and as thin-walled as possible. To produce this protective liner, Welch Fluorocarbon, Dover, New Hampshire, USA, has now developed a process using a polyetheretherketone film (PEEK film, grade: Vestakeep, manufacturer: Evonik Degussa GmbH, Marl, Germany). Earlier generations of pacemakers were fitted with batteries that had to be recharged daily. Only with the advent of high-performance batteries, however, were patients relieved of this con...

... at the end of 2012 plans raising the capacity by approximately 70 %; the starting capacity of its production plant in Mumbai, India, was around 500 t/a. Evonik AG of Essen, Germany, has a capacity of approximately 500 t/a and is producing Vestakeep PEEK in Changchun, China. There is also a handful of smaller Chinese and India players producing PAEK material. In financial year 2013 (1 Oct 2012 to 30 Sept 2013), Europe remained Victrex’s largest market with a 56 % share, followed by America and A...
