Product Info

PEEK (Polyether Ether Ketone) is a high-performance engineering plastic renowned for its strength, heat resistance up to 250°C, and chemical durability. It’s a top material choice for medical, electronic, aerospace, and precision industrial applications requiring long-term reliability.


1. What is PEEK?
PEEK, or Polyether Ether Ketone, is a premium thermoplastic known for its mechanical strength, heat resistance, and chemical stability. It belongs to the category of high-performance engineering plastics and is widely used in harsh industrial environments.

Its ability to maintain structural integrity under extreme conditions makes it ideal for medical implants, aerospace parts, automotive engines, and precision industrial machinery.


2. Key Properties That Set PEEK Apart

- High Thermal Resistance: Continuous use at temperatures up to 250°C without deformation or loss of mechanical strength.
- Chemical Resistance: Withstands strong acids, alkalis, solvents, and corrosive chemicals.
- Mechanical Strength: Offers excellent tensile and impact strength—ideal for load-bearing components.
- Radiation & UV Stability: Performs well in outdoor and sterilized environments such as clean rooms.
- Electrical Insulation: Maintains strong dielectric properties in high-voltage systems.
- High-Precision Machinability: Suitable for complex shapes using injection molding or CNC machining.


3. Industrial Applications of PEEK

3.1 Medical Industry
PEEK is used in bone screws, spinal cages, and dental devices due to its biocompatibility and resistance to bodily reactions.

3.2 Automotive & Aerospace
Ideal for parts near engines and exhaust systems, such as piston rings and seals, due to its high thermal resistance.

3.3 Electronics
Used in insulation for high-voltage components, connectors, and PCBs requiring high thermal stability and non-flammability.

3.4 Chemical Processing
Perfect for valves, pumps, and pipelines that transport corrosive substances with no leakage or degradation.


4. Key Considerations When Choosing PEEK

- Form Type: Rod, sheet, or precision-molded part—choose based on end-use.
- Performance Needs: Assess temperature range, mechanical load, and dimensional tolerance.
- Cost Efficiency: PEEK is premium-priced—use where high performance justifies the cost.
- Expert Manufacturing: Partner with experienced suppliers to ensure machining or molding meets industrial tolerances.
