Chemical additives
Chemical additives can improve PEEK's resistance to UV rays, increase its flame resistance and chemical resistance, thereby extending the material's life in harsh environments.

PEEK Design Considerations
Temperature Considerations
Due to the high processing temperatures of PEEK, precise temperature control during molding and machining is crucial to avoid deformation and ensure dimensional accuracy.

Wall thickness and geometry
Designing parts with proper wall thickness and geometry ensures structural integrity while minimizing material use, reducing costs and resulting in lighter parts.

Wear and friction
The use of surface finishes and textures, as well a gambling datasets the incorporation of additives, can improve the wear resistance and low friction characteristics of PEEK, which are essential for applications involving sliding or rotational motions.

Parts designed to tight tolerances take advantage of PEEK’s excellent dimensional stability. Control of the molding process and tooling design ensures high accuracy and consistency.

Creep resistance
Design features such as fillets, radii or reinforcing ribs can be incorporated to mitigate creep deformation, taking full advantage of PEEK's high creep resistance.

Comparison of properties: PEEK and other high-temperature polymer versions
Understanding the unique qualities of PEEK plastic compared to other high-temperature polymers is essential to making informed decisions about material selection in construction:

Temperature tolerance
PEEK can withstand continuous exposure to high temperatures, typically up to 250°C (482°F), which is superior to many other thermoplastics.

Mechanical resistance
PEEK maintains high strength and stiffness even at high temperatures, outperforming polymers such as nylon and PBT.

Chemical resistance
PEEK is resistant to a wide range of chemicals, including automotive fluids and harsh cleaning agents, making it more durable in harsh environments than other plastics.
