Material properties of Victrex PEEK

Victrex PEEK (polyetheretherketone) is a high-performance polymer with multiple high-quality properties, making it the best choice for most current and future applications. As an alternative material for metals, composites, and other polymers, Victrex PEEK (polyetheretherketone) has become the current engineering solution due to its high-quality properties.

High temperature resistance

The glass transition temperature of Victrex PEEK and its compounds is 143 ° C (289 ° F), and the melting point is 343 ° C (649 ° F). Independent testing results indicate that Victrex PEEK has a maximum thermal deformation temperature of 315 ° C (599 ° F) (ISO R75, filled with fiberglass) and a long-term usage temperature of 260 ° C (500 ° F) (UL 746B).

Wear resistance

Victrex PEEK has excellent friction and wear resistance properties, among which the PEEK polymer with friction levels of VICTREX 450FC30 and VICTREX 150FC30 has the best friction and wear resistance properties. These materials exhibit good wear resistance under various pressure, rate, temperature, and initial roughness conditions.

Chemical corrosion resistance

Victrex PEEK exhibits excellent corrosion resistance in various chemical environments, even at continuously increasing temperatures. Victrex PEEK is a semi crystalline substance that is insoluble in most common solutions, and even at increasing temperatures, it is insoluble in many organic and inorganic liquids. In general, Victrex PEEK is only soluble in concentrated sulfuric acid.

Fireproof, low smoke and non-toxic properties

Victrex PEEK is highly stable, with a low flammability value of V-0 at 1.45 millimeters (0.057 inches) without the addition of flame retardants. The composition and natural purity of the material result in minimal smoke and toxic gases generated in fire.

Hydrolysis resistance

Victrex PEEK can be used for hundreds of hours in steam or high water pressure above 250 ° C (482 ° F) without significant changes in performance. Components made from these materials can still maintain good mechanical properties in high temperature and high pressure water.

Insulation properties

Victrex PEEK maintains good insulation properties at various electrical frequencies and temperatures.

High strength/weight ratio

Victrex PEEK maintains excellent strength and toughness at various temperatures.

High purity

Victrex PEEK material has high purity, very few free ions, and significant degassing effect.

dimensional stability 

Victrex PEEK is highly stable and generally does not change its properties due to temperature, humidity, chemical corrosion, or physical pressure.
