VESTAKEEP® PEEK Polymers for Medical Applications: Portfolio Includes Powders, Granules, Films, Sheets, and Rods for Short-Term and Long-Term Body ContactEssen, )
VESTAKEEP® is available in two viscosities in two different grades. For medical applications suitable for shortterm body contact, Evonik offers the mediumviscosity compound VESTAKEEP® M2G, the highviscosity variant VESTAKEEP® M4G, and the VESTAKEEP® M4P powder grade.
VESTAKEEP® I2G and I4G granules and I2P powder are available for longterm contact with body tissues, as occurs with implants. A device master file for these grades has been deposited with the U.S. Food and Drug Administration (FDA). Dr. Herbert Groothues, responsible for quality processes for VESTAKEEP®, says: "In extensive documentation we have presented in detail the outstanding product properties of the VESTAKEEP® I series and the controlled process flows of its production. This considerably simplifies the approval of products made from these polymers for our U.S. customers."
Evonik also produces crystalline as well as amorphous VESTAKEEP® PEEK film for medical applications. The films have high chemical resistance and mechanical strength; they are flame resistant and stable even at high continuous working temperatures and have excellent tribological and electrical properties.
Jointly with its partners, Evonik also supplies sheet products of VESTAKEEP I grades. With the solid rods and sheets on offer, the market for machined forms is thus well served.
Evonik has been successfully producing and marketing highperformance polymers for more than 40 years, and is highly valued in the market for its experience in application technology. The company has successfully applied its expertise in injection molding, extrusion, compression molding, and CAE (Computer Aided Engineering) analysis to the VESTAKEEP® molding compounds, which were introduced into the product portfolio in 2007 and made available to Evonik's newly acquired development partners. The collaboration is designed on the basis of a longterm partnership, which also allows for fairly long accreditation periods.
