• Aerospace and space: Lightweight, durable parts that replace metals and reduce aircraft or spacecraft weight.
• Automotive industry: Engine parts, bearings, seals, and high
• load mechanical components.
• Medical technology: Implants (e.g., spinal screws), surgical tools, and sterilizable medical equipment.
• Electronics: High
• temperature components, insulators, and housings.
• Oil, gas, and chemical industry: Seals, valves, and bushings in extreme chemical and thermal environments.
• Exceptional thermal resistance: With a melting point of ~343 °C, PEEK operates continuously at up to 260 °C without performance loss.
• Excellent mechanical strength and rigidity: Maintains load
• bearing capability under prolonged stress and high temperatures.
• Outstanding chemical resistance: Resistant to nearly all chemicals, including aggressive acids, bases, fuels, oils, and solvents.
• Low wear and friction: Ideal for bearings, guides, and dynamic mechanical components.
• Flame retardant and dimensionally stable: Achieves UL94 V
• rating without additives.
• Biocompatibility: Suitable for medical implants and devices without adverse biological reactions.
• Very high cost: Among the most expensive engineering plastics.
• Challenging processing: Requires high melt temperatures and specialized equipment.
• UV sensitivity without additives: Degrades under sunlight without stabilization.
