PEK Coil

Formula: PEK

Form: Coil

Material: Polyetherketone (PEK)

CAS Number: 29658-26-2

Commodity: Polymers

Coil Width: 420mm

The PEK Coil is a polyetherketone film supplied in a range of 34 variations. Known for its excellent mechanical properties and chemical resistance, PEK film is used in aerospace composites, electrical insulation, food packaging and medical devices. With high strength and stiffness even at elevated temperatures, it can be thermoformed into complex shapes while maintaining dimensional stability. The variety of PEK film coils from Goodfellow provides options for prototyping and industrial applications requiring a high-performance polymer film.
