Material baseline
Technical material properties of PEEK
PEEK is frequently selected for its ability to maintain mechanical integrity in extreme environments. Understanding the material baseline is critical when sourcing components for medical, aerospace, or industrial applications.
Material selection
Select the right PEEK grade
Material selection impacts the performance of the final component and the machining strategy. Compare the common PEEK variations below.
Application fit
Virgin PEEK
Unfilled PEEK provides the highest elongation and toughness. It is generally the first choice for medical and food-contact applications because of its purity and chemical resistance.
