PEEK is known for its exceptional performance, delivering a high melting point of around 343 °C, continuous-use temperatures near 250 °C, and a tensile strength typically in the 90–100 MPa range. Its combination of mechanical strength, chemical resistance, dimensional stability, and low moisture absorption makes it one of the most capable engineering polymers for CNC machining. These properties allow machined PEEK components to maintain accuracy and reliability even in demanding aerospace, medical, and industrial environments.

PEEK, or polyether ether ketone, is a high-performance engineering thermoplastic known for its strength, thermal stability, and resistance to harsh chemicals. It belongs to the broader PAEK family and is commonly available in grades such as unfilled PEEK, glass-filled PEEK, carbon-filled PEEK, and bearing-grade variants tailored for wear applications. Its balanced mechanical and thermal properties make it a preferred material for precision-machined components in aerospace, medical devices, electronics, and industrial equipment.
PEEK machining refers to the process of shaping and forming PEEK (polyether ether ketone) using CNC equipment. This allows the creation of precise components for applications that require high heat resistance, chemical stability, and mechanical strength.
PEEK is easier to machine than many high-performance plastics because it maintains dimensional stability and resists deformation. However, it requires sharp tools, controlled feed rates, and proper cooling to achieve the best surface finish and accuracy.
PEEK and PTFE serve different purposes. PEEK is stronger, more heat-resistant, and suitable for load-bearing parts, while PTFE excels in low-friction applications and chemical resistance but is softer and less rigid.
While PEEK is not as strong as steel in terms of absolute tensile strength, it offers an excellent strength-to-weight ratio and can perform in high-stress environments where metal alternatives might be heavier or prone to corrosion.
Yes, PEEK is considered a high-performance engineering polymer, so it is more expensive than standard plastics. Its cost is justified by its exceptional durability, chemical resistance, and ability to operate under extreme conditions.
