Materials - PEEK

Maintains wear resistance and mechanical strength up to 480°F continuous use

PEEK is the performance material of choice for aggressive environments such as high temperatures, wet processes, and heavy loads. It combines exceptional wear, chemical and moisture resistance with very high strength, dimensional stability and stiffness. PEEK can be continuously exposed to hot water or steam with no distortion, corrosion or galling.

​

Unreinforced PEEK is a general purpose material noted for its high elongation and toughness. Glass fiber-reinforced PEEK offers increased strength, stiffness and stability at high temperatures, while carbon fiber-reinforced PEEK gives designers the benefit of excellent compression strength and stiffness and reduced expansion rates. PEEK is easily machined to precise tolerances.
