FAQ

What is the application of PEEK in automotive?

Peek component's robustness and resistance to wear and friction make them suitable for use, such as connectors, bushings, gears, and electrical systems. Additionally, its lightweight nature contributes to fuel efficiency and overall vehicle performance.

What is the chemical composition of PEEK?

Chemical formula of polyetheretherketone (PEEK) Polyaromatic semi-crystalline thermoplastic polymer with chemical structure (-C6H4-O-C6H4-O-C6H4-CO-)n.

What are PEEK composites?

Polyetheretherketone (PEEK) is one of the most capable plastics in the world. Highest strength and stiffness with outstanding chemical and thermal resistance makes PEEK the first choice for applications in medical technology, aerospace and oil and gas production.

What parts are made from PEEK?

Some Examples of parts we can machine from PEEK: Peek O-rings, Peek Seats, Peek Bushings, Peek Bearings, Peek Guide Blocks, Peek Wear Pads, Peek Washers.

What does PEEK stand for?

Polyether ether ketone (PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications. PEEK is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures.

How durable is PEEK?

PEEK plastic is exceptionally resistant to high temperatures and also to wear, chemicals, fatigue, and creep. Its strength-to-weight profile is high enough to rival metals like aluminum, and it will not degrade in chemically or physically harsh environments as metals do.

Is PEEK stronger than carbon fiber?

Compared to neat PEEK, the carbon fibers provide it even higher mechanical strength, high temperature characteristics and superior chemical resistance, making it the material of choice for the harshest environments.

Is PEEK a dielectric material?

PEEK is completely covalently bonded, thus it has no mobile electrons resulting in excellent insulating properties. As a dielectric, however, PEEK is easily polarizable allowing it to store electrical energy. The limit of a dielectric to store this energy is its dielectric strength.

Does PEEK conduct electricity?

PEEK, as a semi-crystalline polymer, possesses excellent electrical insulation properties, meaning it does not conduct electricity. However, being an insulator can lead to the accumulation of static charges on its surface when subjected to friction or rubbing against other materials.
