What is PEEK?

PEEK (Polyetheretherketone) is a high-performance polymer commonly used in CNC machining for applications that require exceptional thermal, chemical, and combustion resistance. Available in various forms like sheets, rods, tubes, or films, PEEK is versatile and ideal for precision machining projects where durability and performance are paramount.

Benefits of PEEK for CNC Machining

PEEK offers exceptional performance for CNC machining, especially in demanding environments. Its key advantages include:

Excellent flexural, tensile, and impact strength

  • Ability to withstand high continuous operating temperatures, exceeding 482°F (250°C)
  • Enhanced mechanical and thermal properties when reinforced with glass or carbon fibers
  • Outstanding resistance to heat distortion
  • Strong chemical resistance
  • Superior dielectric properties at high temperatures and frequencies
  • Exceptional resistance to radiation
  • Excellent wear and abrasion resistance
  • Low emission of smoke and toxic gases
  • Strong resistance to hydrolysis
