Wear Resistance
Wear

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.

PFAS-Free
Pfas-free

PFAS-Free

We do not intentionally add, use or generate PFAS during the manufacture of unfilled Victrex PEEK and PAEK polymers.

High Purity
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 inertion

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

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
Processing

Processability

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