structural integrity under load and temperature changes.

Post by [email protected] »

Wear and Friction : PEEK exhibits low wear and friction characteristics, making it ideal for applications involving sliding contact or moving parts, such as bearings and gears.
Biocompatibility: It is safe for implants and medical devices, hong kong dataensuring compatibility with the human body and meeting strict medical standards.
Dimensional Stability: PEEK plastic exhibits minimal thermal expansion and high creep resistance, ensuring that parts maintain their dimensions and
Flame Retardant: It is inherently flame retardant, with low smoke and toxic gas emissions, and meets fire safety standards for various applications.
Electrical Properties: It offers excellent insulation properties at different temperatures and frequencies, making it suitable for electrical and electronic applications.
Disadvantages
Cost : It is significantly more expensive than many other plastics, which can impact the overall cost of projects and applications.
Wear under certain conditions: Although PEEK has low wear characteristics, it can wear in highly abrasive environments, which may limit its use in such conditions.
Processing requirements : It requires high processing temperatures and specialized equipment, which can complicate manufacturing and increase production costs.
UV Sensitivity: Prolonged exposure to UV can degrade PEEK plastic, requiring UV stabilizers or protective coatings for outdoor applications.
Notch Susceptibility : If a surface defect exists, PEEK can fracture under repeated stress, making it susceptible to notching and potentially compromising its mechanical performance in cyclic loading applications.
Not resistant to all chemicals: Concentrated sulfuric acid and other aggressive substances can attack PEEK, limiting its chemical resistance in specific environments.
Applications of PEEK plastic
Aerospace
PEEK's high strength-to-weight ratio and thermal stability make it an ideal material for aerospace applications such as:

Valves and Seals: Used in hydraulic and fuel systems because of their chemical resistance and durability.
Connectors and Insulation: Provides reliable electrical insulation and mechanical stability.
Bearings and bushings: Low friction and wear resistance make PEEK a suitable material for moving parts.
