Engineered Plastics Solutions – PEEK

When it comes to engineered plastics solutions PEEK is right near the top. In fact, at thyssenkrupp Engineered Plastics we give PEEK stock shapes Super Hero Status because of it’s multiple “Super Powers” which include:

  • Excellent Impact Strength
  • Very high continuous working temperature, up to 482˚F
  • Great resistance to steam, perfect for autoclave
  • Good wear and abrasion resistance, can be enhanced with fillers
  • Able to absorb high doses of gamma radiation
  • Great upgrade from PTFE
  • Low smoke and toxic gas release  
  • Carries a UL94 V-O Rating

In addition to the many features and benefits of PEEK plastic, this material gets even better when you factor in the variations and grades of PEEK. Fillers aid in enhancing specific properties and grades can help meet specific requirements like FDA while a general grade may cost a little less. These can allow you to dial in and get the biggest bang for your dollar and ultimately have a part that truly fits the needs of your particular application.

  • PEEK Is Available In Grades to Fit Your Specific Needs
  • General Purpose Grade 
  • (Unfilled) Exhibits high purity, high toughness, and high elongation
  • FDA Compliant Grade
  • For high temperature food applications
  • Bearing Grade (HPV)
  • (Carbon Fiber Reinforced with Graphite and PTFE)
  • Life Science Grades
  • (Approved for USP and ISO 10993-1)
  • Semiconductor Grade
  • (SEMITRON® MP370) Use in Test Sockets and Wafer Cones
When you are looking to replace metal parts or improve the performance of a plastic part ask us if PEEK might be a good alternative. While its true that, as you move toward the top of the triangle, engineering plastics and high performance materials may have an initial higher cost, but upon closer analysis many customer have found the benefits far outweigh the cost and, in the long run they find savings and value through improved part life performance and more.
