• It has a high glass transition temperature (143°C) and melting point (343°C), ensuring stability in extreme heat.
• Unlike traditional plastics, PEEK does not deform or lose strength in high-temperature environments.

1.2 Exceptional Mechanical Strength

• PEEK exhibits a high tensile strength of up to 100 MPa, allowing it to withstand intense loads.
• It resists creep and deformation under continuous stress, making it perfect for high-pressure applications.
• Its durability ensures a longer lifespan compared to conventional plastics and some metals.

1.3 Superior Chemical and Corrosion Resistance

• PEEK is resistant to acids, solvents, fuels, and corrosive chemicals, making it ideal for chemical processing and oil & gas industries.
• It does not degrade when exposed to hydrocarbons, steam, or aggressive cleaning agents.

1.4 High Wear and Friction Resistance

• PEEK has excellent wear resistance, making it perfect for dynamic sealing components, bearings, and valve seats.
• It performs well in high-speed, high-load applications, reducing maintenance needs and downtime.
