Polyetheretherketone, also known as PEEK, is a high-performance engineered plastic uniquely suited to extreme environments, offering advanced resistance to harsh chemicals, outstanding dimensional stability, and excellent mechanical strength. PEEK exhibits hydrolysis resistance and can withstand exposure to extreme temperatures—up to 249°C (480°F) in continuous use. Moreover, this high-performance plastic produces minimal smoke or toxic fumes when exposed to flame and carries a V-O flame rating.
Due to its unique characteristics that enable it to perform well in extreme environments, PEEK plastic is commonly used for demanding applications and high-wear components across various industries, including aerospace, chemical & gas, healthcare, filter manufacturing, pharmaceuticals, and food and beverage. Thanks to its resistance to hydrolysis and ability to withstand continuous exposure to extreme temperatures, hot water, and steam, PEEK plastic is also widely favored in the medical device and life sciences industries, where plastics undergo autoclave sterilization.
