PEEK Material & Properties

High Temperature, Wear & Chemical Resistance

PEEK (polyetheretherketone) is a high-performance engineering plastic with outstanding resistance to harsh chemicals, and excellent mechanical strength and dimensional stability. It offers hydrolysis resistance to steam, water, and sea water. PEEK has the ability to maintain stiffness at high temperatures and is suitable for continuous use at temperatures up to 338oF (170oC). This engineering plastic has a proven track record in challenging environments such as aerospace, oil and gas, food and beverage processing, and semiconductor.

PEEK Properties and Material Options

Virgin PEEK (unfilled) ARKPEEK-1000– is naturally abrasion resistant.

Carbon-Filled PEEK ARKPEEK-CF30- Carbon fiber reinforcement lends the material a high level of rigidity and creep strength, high mechanical strength and heat conductivity values.

Glass-Filled PEEK ARKPEEK-GF30– offers enhanced mechanical and thermal properties over those of basic PEEK, plus excellent resistance in harsh chemical environments and is electrically insulative.

Bearing Grade ARKPEEK-MOD– has enhanced bearing and wear properties. It is an ultra high performance bearing material with wear enhancing additives.

FDA Compliant PEEK– grades available that meet FDA requirements.
