Polymer meets lubrication needs in dental system
When Star Dental needed a material for the sliding vanes and bushings in motors for dental attachments, it chose Victrex Peek polymer because of its lubricity and ability to withstand sterilizations
Polymer protects cylinder head gasket
When STE developed its new Monomet cylinder head gasket, it used a powder coating compound of Victrex Peek polymer and PTFE.
Its outstanding mechanical properties and processability make it an excellent substitute for metals and thermosets in a wide range of aerospace, offshore, medical and industrial applications.
Victrex Peek polymer is available in several viscosities including standard, medium and very low.
Standard and medium grades are ideally suited for highly filled composites where the low viscosity grade enables better dispersion and/or wetting of tape or fabric composite forms.

Polymer seals out high-pressure steam
Victrex Peek 450GL30 has enabled Magnetrol International to develop a guided wave radar probe that reliably seals out high-temperature steam.
These composite forms are engineered to provide optimum impregnation of the reinforcing fibres and fibre-matrix interface.
Victrex Peek composites can withstand continuous operating temperatures of up to 260C in low stress applications, and 120C wet in aerospace structural applications.
Key features include excellent thermal stability and low coefficient of expansion, abrasion resistance, low smoke and toxic gas emission, excellent stiffness and density as well as excellent hydrolysis, corrosion, chemical and radiation resistance.
Victrex partners with leading composite manufacturers to produce a variety of composite forms including: dry fabrics, multi-axial fabrics, braid, tow, unidirectional tape, unidirectional sheet and consolidated fabric.
Victrex also works directly with end users as part of a special development program to ensure that end users achieve the best possible performance from the Victrex Peek composite.
Victrex provides technical support in the form of prototyping, design and commercialisation assistance for single projects at prepreg manufacturing operations and at end user consolidation plants.
Victrex Peek composites have an indefinite shelf life and can be stored at ambient conditions.
Produced in a solvent-free working environment, Victrex Peek has a very stable melt and offers a wide processing window - between 360 and 400C.
Victrex Peek composites are compatible with a wide range of rapid, automated and economical fabrication processes including: compression moulding, roll forming, thermoforming and stamping, pultrusion, filament winding, autoclave and vacuum bag moulding, diaphragm forming; and bladder inflation moulding.
