Key Benefits of PEEK Engineering Plastic
PEEK (Polyether Ether Ketone) is a premium engineering plastic used where extreme temperature and chemical resistance are required. Key benefits include:
- Very High Heat Resistance: Maintains mechanical properties at continuous operating temperatures well above most engineering plastics.
- Excellent Chemical Resistance: Withstands exposure to a wide range of acids, fuels, and industrial chemicals.
- High Strength At Elevated Temperature: Retains mechanical strength and stiffness where other plastics soften.
- Low Flammability: Inherently resistant to ignition without additional additives.
Because of its performance and cost, PEEK is typically specified for demanding applications where lower-cost plastics cannot meet the temperature or chemical exposure requirements.
Common Applications of PEEK Engineering Plastic
PEEK is used in high-performance industrial applications, including:
- Oil and gas downhole and process components
- High-temperature seals and bearings
- Semiconductor and process equipment parts
- Pump and valve components exposed to aggressive chemicals
- Custom precision-machined high-performance parts
See our full Engineering Plastics Product range for other polymer grades, or our Technical Engineering Plastic Products page for material selection guidance.
PEEK Bushes, Gears and Machined Components
PEEK combines high temperature resistance, chemical resistance and high strength and stiffness. Besides PEEK rods and sheets, we supply:
- PEEK bushes — for high-load, high-temperature bearings
- PEEK gears — machined to your tooth profile
- Machined and fabricated PEEK components — seals, seats, insulators and wear parts to your drawing

Q1. What Is PEEK Used For?
A. PEEK is used for high-temperature, chemically demanding applications such as oil and gas downhole components, high-temperature seals and bearings, and semiconductor equipment parts.
Q2. Why Is PEEK More Expensive Than Other Engineering Plastics?
A. PEEK offers a combination of heat resistance, chemical resistance, and mechanical strength at elevated temperatures that few other plastics can match, which is reflected in its cost.
Q3. What Temperatures Can PEEK Withstand?
A. PEEK maintains its mechanical properties at continuous operating temperatures well above standard engineering plastics; exact ratings depend on grade and application, so our team can advise on the right grade for your conditions.
Q4. Do You Offer Custom Machining For PEEK Components?
A. Yes, we provide custom cutting to precise dimensions and CNC machining for PEEK components, in addition to standard stock sheets and rods.
Q5. Do You Deliver PEEK Products Across Saudi Arabia And The GCC?
A. Yes, Diode Trading EST supplies PEEK sheets and rods across Saudi Arabia and the wider GCC, with material test certificates (MTC) available on request.
