PEEK Properties Overview
The true strength of PEEK polymers is in its diverse properties. If you simply have one or two specific engineering requirements alternative engineering polymers will likely work. But for demanding operating environments with three or more engineering requirements – that’s when engineers choose PEEK polymers, often replacing metals and other polymers.
Temperature Resistance
Temperature Resistance
Excellent high temperature performance:
Melting point (Tm) = 343ºC
Glass transition (Tg) = 143ºC

Wear Resistance
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

PFAS-Free
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
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
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
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
Processability
Victrex materials are some of the highest performing materials melt processable using conventional thermoplastic processing equipment.

Recyclable
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.

Processing
Process with ease when specifying VICTREX PEEK high-performance polymers
VICTREX PEEK polymer is capable of being processed on conventional thermoplastic equipment. Unfilled and filled grades may be supplied in the form of granules, powder or ultra-fine powder. Granules are generally recommended for injection moulding, extrusion, monofilament and wire coating operations. Powder is used for compression moulding whilst fine powders are generally used for coating processes and composite pre-preg manufacture.
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.

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.
