About PEEK plastic

PEEK Plastic (polyetheretherketone) belongs to the polyaryletherketone (PAEK) family and is a semicrystalline thermoplastic. It is an almost perfect plastic for parts and components used in environments with high temperatures and high corrosion.

PEEK Plastic’s unique chemical structure makes it incredibly strong and dimensionally stable under load and in the harshest environments. The operating temperature is up to 260°C (480°F), and the melting point is around 341°C (646°F). Therefore, PEEK Plastic is often used in hot water or steam environments.

PEEK plastic is naturally light brown or tan and available in black. It is usually extruded into sheets, films, rods, tubes, and complicated parts by injection molding. Unlike other polymers, PEEK plastic offers machinability similar to that of metal. PEEK Plastic is also available in different grades, such as Unfilled Grade, Glass-Filled, Carbon-Filled, Antistatic PEEK, Etc.

As a popular material, PEEK plastic is used for Semiconductor components, automotive washers/bearings, aerospace parts, oil and gas components, medical devices and implants, and pump/valve components, among other uses.

Frequently Asked Questions about PEEK Plastic

Yes, polyetheretherketone can easily be injection molded. You can mold your PEEK using standard injection molding machines from a qualified supplier. The PEEK plastic is molded under a specific temperature. The processing temperature ranges from 350 to 400°C, or 662°F to 752°F. The standard injection molding machines can easily take these necessary temperatures and mold PEEK with the use of built-in cylinder heaters.

Yes, PEEK is a durable plastic that can be used in any environment where high chemical resistance is important. Besides, it can withstand high temperatures and doesn’t break down or melt in regular wear, such as hot water or steam. The best PEEK offers strong performance without being heavy. It has a high strength-to-weight ratio compared to aluminum.

PEEK has a V-0 flammability rating. That means it is highly flame-resistant. It can handle continuous exposure to temperatures even if it goes up to 480°F (250°C) without losing its physical structure. Even when it comes to flame, it produces very little smoke and toxic gas. Its melting point is 343 °C. For this reason, you can use this plastic in applications where fire safety is a concern.

PEEK is a highly resistant plastic that is resistant to wear and tear. The Young’s modulus of elasticity of the PEEK is about 3.6 GPa. Besides, its tensile strength is 170 MPa. Therefore, this plastic is exceptionally strong and resilient. You can operate it on challenging applications like aerospace, automotive, or medical devices.

Yes, you can 3D print PEEK. The print working procedures are almost the same as other 3D printing processes. The processing temperatures for 3D printing range from 370° to 450° Fahrenheit. Besides, the temperature of the build plate always stays at least 120°. But all you need is to ensure that your printer can effectively maintain a stable temperature for fluent printing.

No, PEEK and Teflon are not the same. PEEK is often chosen for those applications where high strength and minimal deformation under stress are the top priorities. Besides, you can use PTFE or Teflon in applications requiring precise resistance to electrical voltage or chemicals. Also, Teflon is affordable enough compared to PEEK.

No, PEEK is sensitive to UV radiation. Under direct sun exposure, the plastic can discolor, change shape, or even break in severe cases. This is the only reason you can’t use it in outdoor applications or store it under direct sunlight.

Filled PEEK is a special type of polyetheretherketone. It may contain special additives, such as carbon fiber, glass fiber, or other fillers. On the other hand, unfilled PEEK is a pure material. It is excellent in durability and has high resistance.

This thermoplastic polymer comes in a variety of colors. We offer plastic in natural color tones, and black is also available if you prefer. It can be used for instrument and seal components. However, the standard color of polyether ether ketone is light brown or tan.

Yes, polyether Ether Ketone is a recyclable plastic. Mechanical recycling is a common method for this. In this method, PEEK is shredded into small pieces and then melted. Finally, it is molded into new products. Another popular method is chemical recycling, where PEEK is broken down into its basic chemical components. Then, it is used to make new materials.

Yes, obviously! PEEK is known for its amazing flexibility, which is possible due to its outstanding chemical resistance and mechanical strength. The PEEK tube features a high-quality flex fiber, which is used to make expandable braided sleeves. Generally, you will find it in wires and hoses to protect them from frequent wear and tear.

No, PEEK is typically difficult to machine. You will need to be a professional in this instance. Plus, you need to go through some special processes and the right tools to get the right quality parts. Different methods are used in these instances, like turning, milling, drilling, and grinding.

To find the right PEEK for your specific projects, you should have a good understanding of its structure, properties, and processing methods. Check its color tone; it should be a natural beige color. When it is in an amorphous state, it will appear as transparent amber. Also, touch its structure. It is very hard, and you should hear a clear sound when you knock it with a coin.

PEEK is a popular plastic used in different medical applications, such as hip replacements, spinal fusion cages, trauma fixation plates, femoral stems, etc. It is also used in various dental applications as well. Like dental implants, maxillofacial orthodontic brackets, or cranial implants.

Yes, PEEK is naturally hydrophobic, so it does not absorb moisture. It is also resistant to hydrolysis in water, steam, and seawater and effectively withstands these without losing its physical properties. Thus, it can be used in applications where moisture resistance is essential.

PEEK can work well for a long time at a temperature of 240 °C.
