Advanced Engineering Plastics (PEEK / PEKK / Vespel™)

DMR Seals hold an extensive range of semi-finished advanced engineering plastic materials in stock to enable rapid turnaround of finished products to our customers. Advanced engineering plastics such as PEEK, PEKK, PBI and others can offer many advantages over metallic materials when chosen correctly. Advanced engineering plastics offer the design engineer excellent mechanical and thermal properties while providing superior chemical and corrosion resistance. Listed below are just a few of the advantages that can be found using advanced engineering plastics in place of metallic components:

  • Elimination of lubrication enabling dry running
  • Reduced wear on mating parts
  • Reduced friction providing faster operating speeds
  • Lower torque values resulting in reduced power consumption
  • Improved corrosion and chemical resistance
  • Compliance with industry specifications such as Norsok M-710

DMR Seals understand that choosing the correct advanced engineering plastic for your application can sometimes be tough. By taking careful consideration of your application conditions, such as temperature, load, speed and chemical compatibility, this process can be made much simpler and provide you with the full benefits of using these materials. Please contact our technical team should you require any help choosing the correct material for your application or if the material you require is not shown.
