What is PEEK material?

PEEK material (polyetheretherketone) is a high-performance semi-crystalline engineering thermoplastic with outstanding harsh chemical resistance, very low moisture uptake, good fire performance, excellent mechanical strength across a broad temperature range, and good dimensional stability.

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 material ESD safe?

PEEK SD is an electrically modified PEEK ESD plastic material with a defined surface resistance between 106 -109 Ohm. Such materials are also referred to as ESD safe materials. PEEK ESD has excellent dimensional stability and can be machined easily to very tight tolerances.

Is PEEK a good bearing material?

PEEK is a high performance thermoplastic that is tough, strong, rigid, and creep resistant. Bearing Grade PEEK has been reinforced with carbon fibers with graphite and PTFE lubricants. It offers the lowest coefficient of friction, and the best machinability of the PEEK grades.

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).

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.

Is PEEK static dissipative?

PEEK ESd – Properties and Applications PEEK ESd is a static-dissipative, carbon fiber reinforced PolyEtherEtherKetone ideal for when PEEK’s properties are needed, but protection from static discharge is also a requirement.

How do you manufacture PEEK?

Synthesis of PEEK requires accurate reaction conditions because of its insolubility. PEEK can been synthesized by using nucleophilic substitution of 4,4′ – difluorobenzophenone with hydroquinone in the presence of anhydrous potassium carbonate under microwave irradiation to produce a good yield.

What plastic can withstand high temperatures?

High-Temperature Plastics are available from Regal Plastics. Materials that can exceed 300 F in continuous operating temperature are typically classified as High Temperature. These materials include products such as Torlon™, PEEK™, Teflon™, and Rulon™.

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.

What kind of chemical resistance does Peek plastic have?

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.

What makes Peek a high-performance thermoplastic?

Polyetheretherketone (PEEK) is a high-performance, engineering thermoplastic characterized by an unusual combination of properties. These properties range from high temperature performance to mechanical strength and excellent chemical resistance. But, what are the key characteristics which make PEEK a high-performance plastic?

What are the properties of Peek in water?

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 o F (170 o C).

What are the properties of Virgin Peek plastic?

Virgin PEEK (unfilled)– is naturally abrasion resistant. Glass-Filled PEEK– offers enhanced mechanical and thermal properties over those of basic PEEK, plus excellent resistance in harsh chemical environments and is electrically insulative.
