VICTREX™ PEEK 450FE20: a tribologically engineered, low-friction PEEK
VICTREX™ PEEK 450FE20 is a type of polyetheretherketone (PEEK) containing 20% PTFE, developed to withstand the demands of applications subject to friction, wear, and high mechanical loads. It represents an advanced engineering solution for components that require reliable operation without external lubrication, while maintaining excellent dimensional stability.
This material is positioned as an optimal compromise between the rigidity of unreinforced PEEK and the sliding properties of PTFE, enabling parts to last longer during use.
Tribological and mechanical properties
VICTREX™ PEEK 450FE20 stands out for:
- a significant reduction in the coefficient of friction compared to standard PEEK,
- a significantly improved wear resistance, including when operating under dry-running conditions,
- o increased creep resistance, which is essential for bearings and rings subjected to load,
- an increase in PV limits, which allows for use in challenging conditions.
These properties help minimize overheating, seizing, and premature wear of components in sliding contact.
Thermal and chemical resistance
Thanks to its PEEK matrix, the 450FE20 grade retains:
- excellent thermal resistance, suitable for high operating temperatures,
- very good chemical resistance to numerous solvents, hydrocarbons, acids, and bases,
- low moisture absorption, which ensures long-term performance stability.
These characteristics make it a suitable material for demanding industrial environments, including regulated sectors.
Industrial Applications of VICTREX™ PEEK 450FE20
VICTREX™ PEEK 450FE20 is commonly used in the manufacture of:
- bearings, rings, and self-lubricating bearings
- guides, guide rails, and friction pads
- mechanical parts that operate in a dry environment
- components for medical devices and analytical equipment
- aeronautical, automotive, and industrial applications that require reliability and durability
For applications in the field of dynamic cryogenics, a specialized material such as VICTREX™ PEEK CT200 is more suitable.
Transformation and implementation
VICTREX™ PEEK 450FE20 is available in the form of granules and semi-finished products and can be processed using:
- extrusion,
- injection molding,
- machining of precision technical parts.
It is particularly recommended for projects that require strict tolerances, high material repeatability, and extended component service life.
