Polyetherketone (PEK) is a semi-crystalline high-performance thermoplastic from the polyaryletherketone (PAEK) family. Known for its extreme heat resistance, mechanical strength, and chemical stability, PEK shares similarities with PEEK but offers a higher melting point and even better thermal performance, making it suitable for the most demanding technical applications.Polyetherketone (PEK) is a semi-crystalline high-performance thermoplastic from the polyaryletherketone (PAEK) family.

• Aerospace industry: Structural components, interior cabin parts, electrical insulators, and brackets requiring heat resistance and low weight.
• Oil and gas industry: Seals, valves, bearings, and parts exposed to extreme chemicals and heat.
• Automotive industry: Engine, transmission, and other components needing wear and thermal resistance.
• Electronics: High heat
• resistant circuit board components, connectors, and insulators.
• Medical technology: Surgical instruments and devices requiring sterilization, purity, and longevity.
• Very high thermal resistance: Maintains performance above 250 °C with a melting point around 375 °C, ideal for long
• term use in extreme heat.
• Outstanding mechanical strength and rigidity: Performs under continuous mechanical loads and high temperatures.
• Exceptional chemical resistance: Resistant to nearly all chemicals including strong acids, bases, fuels, oils, and solvents.
• Wear and friction resistance: Low wear and friction make it suitable for dynamic mechanical parts.
• Flame resistance and low smoke emission: Complies with strict fire safety standards—suitable for critical safety systems.
• Very high cost: Among the most expensive thermoplastics, limiting use to highly specialized sectors.
• Challenging processing: Requires extremely high processing temperatures and specialized equipment.
• Limited availability: Lower production volumes and niche use lead to limited global supply.
