What makes PEEK so expensive?

What makes PEEK so expensive?

High performance polymers are becoming available for specific applications. One of such materials is PEEK (PolyEther Ether Ketone), a thermoplastic polymer in the polyaryletherketone (PAEK) family. PEEK competes with certain Aluminium alloys but is half the weight of Aluminium.

Why is PEEK plastic so expensive?

Why is PEEK So Expensive? The price point for PEEK (polyetherketone) often comes as a surprise to clients. However, these other polymers can’t compete with the advanced properties of PEEK. PEEK is commonly used to produce high-quality plastic parts that electrically and thermally insulating, as well as thermostable.

Is PEEK plastic expensive?

Interest among plastics processors in polyetheretherketone (PEEK), an engineering thermoplastic that offers a mighty array of mechanical properties including very high heat resistance and strength, is dampened by the material’s price tag, which exceeds $10/lb.

How much does PEEK material cost?

Sources estimate the price of medical-grade PEEK at close to $400 per pound for injection molding material compared to about $44 per pound for industrial-grade PEEK. The price is much higher, above $1,300 per pound, for PEEK supplied as a machinable billet.

How strong is PEEK?

Its Young’s modulus is 3.6 GPa and its tensile strength is 90 to 100 MPa. PEEK has a glass transition temperature of around 143 °C (289 °F) and melts around 343 °C (662 °F).

What is special about PEEK?

Polyetheretherketone (PEEK) is a semi-crystalline, high-performance engineering thermoplastic. This rigid opaque (grey) material offers a unique combination of mechanical properties, resistance to chemicals, wear, fatigue and creep as well as exceptionally high temperature resistance, up to 260°C (480°F).

Is PEEK toxic?

Toxicity of PEEK is expected to be low based on insolubility of polymer in water. Natural polyetheretherketone (PEEK) such as UNITREX PEEK does not contain any known toxic chemicals listed under Section 313 of Title III of the Superfund Amendments and Reauthorization Act (SARA) of 1986 and 40CFR part 372.

What is PEEK plastic used for?

Because of its robustness, PEEK is used to fabricate items used in demanding applications, including bearings, piston parts, pumps, HPLC columns, compressor plate valves, and cable insulation. It is one of the few plastics compatible with ultra-high vacuum applications.

Is PEEK stronger than steel?

The inherent low specific gravity of VICTREX PEEK (1.3 g/cm3) is less than half that of aluminium and one sixth that of steel. This results in a superior strength-to-weight ratio so VICTREX PEEK-based compounds can offer equivalent strength and stiffness with up to 70% weight reduction.

Is PEEK waterproof?

Due to its resistance to hydrolysis, and very low moisture absorption, PEEK can withstand boiling water and superheated steam which are used in autoclave and sterilization equipment,.

Can you sterilize PEEK?

Do not reuse, reprocess, or resterilize this product. Reuse, reprocessing, or resterilization may compromise the structural integrity of the device and/or create a risk of contamination of the device, which could result in patient injury, illness, or death.

Why is PEEK so strong?

PEEK can tolerate mechanical and physical stress, and also has excellent chemical resistance and high heat tolerance, which together provide this material with advantages over metal parts. These qualities make PEEK suitable for the automotive, aerospace, and other general industrial settings.

Why is Peek plastic so expensive per pound?

PEEK plastic price per pound is generally higher than other high-temperature thermoplastics, but it also offers benefits that other resins lack. Why is PEEK So Expensive? The price point for PEEK (polyetherketone) often comes as a surprise to clients. However, these other polymers can’t compete with the advanced properties of PEEK.

What makes Peek different from other 3D printing filaments?

PEEK belongs to a class that’s a little different than most of the other 3D printing filaments. It’s classified as a high-performance filament, which means that it exhibits better overall properties. However, this also corresponds to a much higher price tag.

Are there any companies that make PEEK filaments?

Netherlands-based 3D4MAKERS is one of only a few companies that manufacture and sell PEEK filaments. Their PEEK filament has excellent mechanical properties, prints at very high temperatures, and has been FDA-approved for contact with food.

What are the thermal properties of Peek filament?

As you would expect, PEEK has thermal stability unequaled in the world of 3D printing filaments. With thermal stability of up to 250 °C, PEEK is a suitable material for many engineering processes or medical instruments and prosthetics that need to be sterilized at high temperatures.
