PEEK (Polyetheretherketone)

Used where chemical and liquid resistant is essential

PEEK is a strong and stiff thermoplastic material that is often used in applications where performance at elevated temperatures is required. PEEK has outstanding chemical resistance as well as resistance to steam and hot water. Virgin PEEK or unfilled PEEK is naturally abrasion resistant. Bearing grade PEEK has enhanced bearing and wear properties.


PEEK Performance benefits are:
•    Strong and stiff plastic
•    Outstanding chemical resistance
•    Good mechanical properties at elevated temperatures
•    Resistant to hot water and steam
•    Bearing grade PEEK has excellent wear characteristics
•    UL 94 V-0 flammability rating (0.059" thickness)
•    Very low smoke and toxic gas emissions when exposed to flame


Typical Applications of PEEK are:
•    Semiconductor machinery components
•    Aerospace parts
•    Seals
•    Pump and valve components
•    Bearings and bushings (bearing grade PEEK)
•    Electrical components
•    Medical instrument parts
•    Food processing machinery components
