What is PEEK?

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 338°F (170°C).

What is the difference between virgin unfilled PEEK and glass-filled PEEK?

Virgin Unfilled PEEK – is naturally abrasion resistant.

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

What are common brands of PEEK?
PEEK is also known as TECAPEEK®, SustaPEEK, Ketron®.

What are common PEEK applications?
PEEK is widely used for semiconductor machinery components, aerospace parts, bushings, bearings, seals, pump and valve components, medical instrument parts, food processing machinery components, and many more applications.
