Polyetheretherketone (PEEK)

PEEK (Polyetheretherketone) — High-Performance Engineering Plastic

Polyetheretherketone (PEEK) is a semi-crystalline high-performance thermoplastic with outstanding mechanical properties, chemical resistance, and thermal stability. We supply Solvay KetaSpire® PEEK — one of the world's most trusted PEEK brands — in resin pellets and machined semi-finished forms.

Why Choose PEEK?

  • High Temperature: Continuous service to 260°C; melting point 343°C
  • Mechanical Strength: Fatigue resistance comparable to metal alloys
  • Chemical Resistance: Resistant to virtually all common organic and inorganic chemicals; only dissolves in concentrated sulfuric acid
  • Wear & Friction: Excellent tribological performance; self-lubricating grades available
  • Electrical Insulation: Stable dielectric properties across a wide temperature and frequency range
  • FDA / USP Class VI compliant grades available
