Evonik Launches VESTAKEEP® Ultimate Offering Sealing Benefits

Published on 2011-10-19. Author : SpecialChem

Evonik Industries is now unveiling an improved polyether etherketone (PEEK) called VESTAKEEP® Ultimate.

The new VESTAKEEP® Ultimate PEEK polymer offers unique properties such as:
  • A 25% higher impact strength compared to state of the art PEEK Polymer
  • Enabling to double the lifespan of dynamically stressed molded components
This technical enhancement facilitates certain high-performance solutions, which may make it the material of choice for PEEK polymer in a vast range of applications:
  1. VESTAKEEP® Ultimate, exceptional properties provide greater resilience to higher stress exposed components in Automobile and Aircraft industries. For example Sensors or Ball Bearings benefit from the high abrasion resistance.
  2. When used as a sealant material VESTAKEEP® Ultimate, offers benefits by withstanding high temperatures at depths of several hundred meters for Oil & Gas industry.
  3. VESTAKEEP® Ultimate also increases process reliability in semiconductor manufacturing- for example in the production of silicon wafers. This is due to the high temperature resistance of VESTAKEEP® and its particularly low ion content.
  4. VESTAKEEP® Ultimate provides advantages at the processing level too. Its high melt elasticity allows pipes with large diameters to be manufactured more easily.

In introducing the new PEEK, Evonik once again is demonstrating its innovative strength in the field of high-performance plastics. "VESTAKEEP® Ultimate shows that there is a long way to go before the crest of the plastics pyramid is reached," states Dirk Heinrich, Director Business Management VESTAKEEP®. "And development hasn't even been finished yet: We are continuing to work hard on improving our products to support our customers to meet performance requirements".
