VICTREX™ PEEK polymers:
Materials For Demanding Applications
- - One of the world’s highest performing thermoplastics
- - High-performance engineering polymer that excels in extreme conditions
PEEK Properties Overview
Temperature Resistance
Excellent high temperature performance:
- Melting point (Tm) = 343ºC
- Glass transition (Tg) = 143ºC
- Operating temperature = up to 260℃
- V-0 flammability rating
See details of other thermal properties and compare the Victrex polymer grades:
Chemical Resistance
Excellent resistance to a very wide range of chemicals over a range of temperatures, retaining high levels of mechanical strength and generally with little swelling or discolouration.
Mechanical Strength
Excellent strength, stiffness, long-term creep and fatigue properties.
See details of mechanical properties and compare the Victrex polymer grades:
Wear Resistance
High abrasion and cut through resistance combined with a low coefficient of friction.
Victrex materials are used for tribological components due to their outstanding resistance to wear in high pressure and velocity environments.
Electrical Properties
Victrex materials are often used as an electrical insulator with outstanding thermal, environmental resistance and mechanical performance.

PFAS-Free
We do not intentionally add, use or generate PFAS during the manufacture of unfilled Victrex PEEK and PAEK polymers.
View our page on PEEK as “Sustainable alternative to PFAS concerns”
High Purity
Victrex materials are inherently pure with very small amounts of low molecular weight volatile organics, resulting in exceptionally low outgassing and extractables even in high vacuum environments.
Bio-Inert
Our medical grade polymers are biocompatible, and one of the most chemically resistant thermoplastics available; it exhibits a superior combination of strength, stiffness and toughness, making it ideally suited for medical device applications such as drug delivery, dental abutments, catheters, blood management and surgical instruments.

Hydrolysis Resistant
Victrex high performance polymers are not attacked by prolonged exposure to water, sea water or steam which makes them an ideal choice for use in applications such as medical components, subsea equipment, and valve components.
Processability
Victrex materials are some of the highest performing materials melt processable using conventional thermoplastic processing equipment.
Recyclable
Due to its high molecular stability, PEEK polymers can be re-melted and reprocessed repeatedly with minimal change to its properties. This helps its environmental footprint and can ensure that waste material from manufacturing processes can be re-used economically.

Process with ease when specifying VICTREX PEEK high-performance polymers
- Injection Moulding
- Extrusion
- Compression Molding
Most standard reciprocating screw injection moulding machines are capable of moulding unfilled and filled VICTREX PEEK grades. Complex and intricate high performance components can be mass-produced without annealing or conventional machining. Victrex technical experts can assist with design and process variables such as machine design, barrel capacity, screw and mold design and gating.
- Injection Moulding
- Extrusion
- Compression Molding
VICTREX PEEK thermoplastics can be used in extrusion processes and equipment including wire coating, profile extrusion, film, pipe, sheet and monofilament production. Unfilled and filled grades are readily extruded using conventional melt processing technology. Our highly experienced technical team can help define the machine design and address any processing challenges.
- Injection Moulding
- Extrusion
- Compression Molding
Compression moulded parts are generally more crystalline, have a higher modulus and tensile strength and are harder with a lower ductility. Glass and carbon fibres may be combined with VICTREX PEEK for compression moulding. Our technical team recommends that our customers anneal parts with very thick sections to relieve stresses.
