Possible Applications

Carbon fibre filled VICTREX PEEK is more expensive to produce, but is commonly used in applications where a superior strength-to-weight ratio is required.  The material is used in numerous applications across multiple industries such as aerospace, civil engineering, sports equipment and a number of consumer and industrial applications.

The material's excellent strength has led to it being used in high-performance motor racing as components created with the material have a lower weight than their metal counterparts (and also offers the benefits of less water and electricity used during manufacturing).

The construction industry also uses carbon fibre filled VICTREX PEEK to reinforce a range of concrete, masonry, steel, cast iron and timber structures.


Other applications include:

Valve seats, wear bands, bearings, bushes (high load wear) other non metallic wear parts
