Description
PEEK (Polyether Ether Ketone) is a high-performance thermoplastic engineering plastic known for its exceptional heat resistance, mechanical strength, chemical stability, and wear performance. It combines the toughness of metals with the lightweight and corrosion resistance of plastics, making it suitable for demanding industrial environments. PEEK can be supplied as Sheet, Rod, Tube, and precision-machined parts, and can be reinforced with carbon fiber, glass fiber, or solid lubricants to further enhance mechanical strength, stiffness, and wear resistance.
Features
Excellent heat resistance (continuous use up to 260°C)
High mechanical strength and outstanding fatigue resistance
Self-lubricating with low coefficient of friction
Excellent chemical and corrosion resistance
Flame retardant (inherent, no additives required)
Very low moisture absorption and good hydrolysis resistance
Outstanding wear and abrasion resistance
Excellent electrical insulation properties
Applications
Aerospace: Structural components, interior parts, lightweight metal replacement
Electronics & Semiconductor: Insulators, wafer carriers, connectors, high-temperature components
Medical: Surgical instruments, dental components, orthopedic implants
Automotive: Bearings, seals, gears, clutch components, engine parts
Industrial Machinery: Valves, piston rings, pump parts, compressor components
Energy & Nuclear: High-temperature cables, insulation frames, radiation-resistant parts
Chemical Processing: Pump housings, seals, and corrosion-resistant components
