PEEK Plastic

Polyetheretherketone

PEEK, short for Polyether Ether Ketone, is a high-performance semi-crystalline engineering thermoplastic renowned for its exceptional robustness. As a member of the polyaryletherketone (PAEK) family, it is an organic polymer that offers a unique combination of mechanical properties and chemical resistance. Its structure makes it an ideal metal replacement in demanding applications where traditional engineering plastics would fail. PEEK maintains its superior performance across a wide range of thermal and mechanical stresses, establishing itself as a critical material in advanced manufacturing.

Firstly, it exhibits outstanding thermal stability, capable of operating continuously at temperatures up to 260°C (500°F) while maintaining its mechanical integrity. Secondly, PEEK is complemented by exceptional dimensional stability, meaning it resists shrinkage and deformation, making it perfect for machining precise, tight-tolerance components. Chemically, PEEK is virtually impervious to a wide range of solvents and corrosive fluids. Furthermore, its electrical properties are notable for having a low dielectric constant and low dissipation factor, making it an excellent insulator for electronic applications.

Due to its versatility, PEEK is utilized across numerous industries. It is widely used in the aerospace sector for lightweight brackets and cable connectors, in the automotive industry for transmission components and seals, and extensively in medical technology for equipment components. It is also the material of choice for semiconductor wafer handling equipment.

To meet these diverse industrial needs, we offer a comprehensive range of PEEK solutions. We supply PEEK in pure resin form, as well as specialized grades including carbon-fiber-reinforcedand glass-fiber-reinforced compounds for increased stiffness. Additionally, we provide specific grades for bearings and anti-static PEEK for electronics applications. Our products are available in stock shapes, including rods, sheets, and tubes, ready for machining into finished parts.

PEEK Materials
PEEK natural rod, plate, tube
PEEK Natural

PEEK natural is an unfilled semi-crystalline high-performance plastic with high continuous temperature, good mechanical strength, excellent dimensional stability, and exceptional chemical resistance.

PEEK black rod, sheet, tube
PEEK Natural Black

PEEK natural black keeps PEEK natural all excellent properties and the black color PEEK has better UV and weather resistance than the beige one. Give customer more choices.

PEEK GF30 natural rod, sheet, tube
PEEK GF30 Natural

PEEK GF30 is a 30% glass fiber reinforced material based on PEEK natural. Compared to PEEK natural, the rigidity and wear resistance are improved, especially under the condition of high temperature and pressure.

PEEK GF30 black rod, sheet, tube
PEEK GF30 Black

PEEK GF30 black shows better UV resistance comparing with natural color which is more suitable for the outdoor environment.

PEEK CF30 rod, plate, tube
PEEK CF30

PEEK CF30 is 30% carbon fiber filled based on PEEK virgin. Because of the carbon fiber, the mechanical strength, rigidity, thermal conductivity and creep strength are improved.
