PEEK properties

PEEK material properties overview


PEEK polymers are well suited for extreme and demanding environments, whether in the form of powder, pellets, or compounds or forms and parts. The light thermoplastic can support multiple requirements at the same time – to solve material limitations in applications, often replacing metals, and to meet cost-efficiency and sustainability needs.

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.

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.

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 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.
