Combining the best of both worlds

VICTREX PEEK compound

COMBINING THE BEST OF BOTH WORLDS

Victrex offers compounded polymers that combine the innate properties of PEEK with the enhanced strength of carbon fibers, glass fibers, and proprietary blends to reach higher performance levels. VICTREX WG™ polymer, for example, provides a low, stable coefficient of friction and excellent wear resistance in high pressure, high velocity applications.

BENEFITS OF PEEK COMPOUNDS:

  • Enhance performance with a high strength-to-weight ratio
  • Increase reliability due to improved fatigue strength and creep resistance
  • Thrive in extreme wear environments with excellent abrasion resistance
  • Deliver increased electrical integrity in demanding applications
  • Improve durability with excellent resistance to a wide range of chemical species

Processing

Process with Ease when Specifying VICTREX PEEK polymers

VICTREX PEEK polymer is capable of being processed on conventional thermoplastic equipment. Unfilled and filled grades may be supplied in the form of pellets, powder or ultra-fine powder. Pellets are generally recommended for injection molding, extrusion, monofilament and wire coating operations. Powder is used for compression molding while fine powders are generally used for coating processes, composite pre-preg manufacture and compression molding.

Most standard reciprocating screw injection molding machines are capable of molding 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 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, extruder size and control and die design.

Compression molded parts are generally more crystalline, have a higher modulus and tensile strength and are harder with a lower ductility. Glass and carbon fibers may be combined with VICTREX PEEK for compression molding. Our technical team recommends that our customers anneal parts with very thick sections to relieve stresses.
