VICTREX® PEEK™ polymer is a high performance polymer with unique properties that makes it an ideal choice for today’s and tomorrow’s most demanding applications.
As a replacement for metals, composites and other polymers, VICTREX PEEK high performance polymer is the engineering solution due to its outstanding combination of properties.
PEEK Polymer High Temperature Performance
VICTREX PEEK and compounds typically have a glass transition temperature of 143°C (289°F) and a melting temperature of 343°C (649°F). Independent tests have shown that VICTREX PEEK exhibits a heat distortion temperature up to 315°C (599°F) (ISO R75, glass fiber filled) and a Continuous Use Temperature of 260°C (500°F) (UL 746B).
PEEK Polymer Wear Resistance
VICTREX PEEK has excellent friction and wear properties that are optimised in the specially formulated tribological grades VICTREX 450FC30 and VICTREX 150FC30. These materials exhibit outstanding wear resistance over wide ranges of pressure, velocity, temperature and counterfacial roughness.
PEEK Polymer Chemical Resistance
VICTREX PEEK has excellent resistance to a wide range of chemical environments, even at elevated temperatures. Insoluble in most common solvents and being semi-crystalline has excellent resistance to a very wide range of organic and inorganic liquids, at elevated temperatures. The only common environment that dissolves VICTREX PEEK is concentrated sulfuric acid.
PEEK Polymer Fire, Smoke and Toxicity Performance
VICTREX PEEK is highly stable and requires no flame retardant additives to achieve a V-0 rating at 1.45 mm (0.057 in) thickness. The composition and inherent purity of the material results in extremely low smoke and toxic gas emission in fire situations.
PEEK Polymer Hydrolysis Resistance
VICTREX PEEK can be used for thousands of hours at elevated temperatures in excess of 250°C (482°F) in steam or high water pressure environments without significant degradation in properties. Components that are constructed from these materials retain a high level of mechanical properties when continuously conditioned in water at elevated temperatures and pressures.
PEEK Polymer Electrical Performance
VICTREX PEEK electrical properties are maintained over a wide frequency and temperature range.
PEEK Polymer High Strength to Weight Ratio
VICTREX PEEK offers exceptionally high strength properties combined with good toughness over a wide range of temperatures.
PEEK Polymer Inherent Purity
VICTREX PEEK materials are inherently pure with exceptionally low levels of ionic extractables and excellent outgassing characteristics.
PEEK Polymer Dimensional Stability
VICTREX PEEK is remarkably stabile, resisting changes to its properties due to temperature, moisture, chemical attack or physical stress.
