Guide to Materials and Sterilization > PEEK


PEEK (POLYETHER ETHER KETONE)

  • Applications:
    • Components in catheters used for coronary valve, stent, or graft delivery
    • Bone cement delivery during orthopedic procedures
    • Ablation, endoscopy, spinal, and vascular applications
    • Potential as replacement for steel components used during many minimally invasive procedures
  • Benefits:
    • High tensile and column strength – one of the highest strength to weight ratio of any thermoplastic
    • High dimensional stability
    • Low flexural modulus – PEEK withstands loads without deflection, which results in high pushability, excellent torque transmission, and the ability to handle buckling loads
    • Very low elongation/elasticity – PEEK withstands force without elongating in the direction of the force
    • High inherent lubricity results in minimal abrasion
    • High chemical inertness
    • High burst pressure
    • High temperature performance/endurance
    • Low conductivity
  • Dimensions:
    • Max OD: 0.500” (12.7mm); min OD: 0.030” (0.762mm)
    • Wall thicknesses: min: 0.005” (0.127mm); max: no maximum specification
    • PEEK extrusion can be customized to the sizes and lengths required for most applications
  • Tolerances:
    • OD ± 0.0005″ (0.0127mm)
    • ID ± 0.0005″ (0.0127mm)
  • Configurations:
    • Single- and multi-lumen
    • Rods
    • Custom profiles and shapes, including keyhole, half moon, and oval
  • Colors:
    • Black
    • Blue
    • Grey
    • Tan (natural)
  • Sterilization:
    • Gamma
    • EtO
    • E-beam
    • Autoclave
