PEEK (Polyether Ether Ketone) is one of the highest-performance engineering thermoplastics in the world. It is known for its exceptional mechanical, thermal, and chemical resistance properties, outpacing many metals and composites, and offering lightweight solutions for demanding applications across various industries. Superior Mechanical Properties. With a tensile strength of 80 MPa, flexural strength of 130 MPa, and impact resistance of 140 kJ/m², PEEK offers metal-like performance. It provides weight-saving benefits, reduces fuel consumption and emissions, and is ideal for aerospace, automotive, marine, medical, and energy applications. Inherent Flame Resistance (UL94 V-0). PEEK maintains flame resistance, making it suitable for high-temperature environments. It can withstand short-term service temperatures up to 260°C and continuous exposure up to 240°C. Its strong layer bonding ensures excellent dimensional accuracy and z-strength. Chemical Resistance. PEEK is highly resistant to oils, automotive fluids, halogenated hydrocarbons, alcohols, and aqueous solutions. It shows exceptional resistance to hydrolysis in hot water and is nearly insoluble in most common solvents. Medical Applications. PEEK is biocompatible, biostable, and x-ray transparent. It’s widely used in medical implants, particularly in orthopedic and spinal applications, due to its durability and resistance to wear and chemical degradation.
