Outstanding physical properties make PEEK ideal for sealing applications

Effective and efficient sealing is an essential part of almost every modern industrial process where gases, liquids and solids are being transported. Seals are needed wherever the containment of these commodities is completed (such as end-caps), measured (flowmeters), controlled (valves) or separated from moving parts.
These countless application possibilities require an equally diverse range of sealing technologies and products. These, in turn, use a wide selection of materials – ranging from soft and flexible elastomers, and various thermoplastic and thermoset polymers to bronzes and steel. 

In some industries, including the oil and gas sector, the primary function of the material is to serve as a mechanical back-up for softer sealing materials, such as elastomers and fluoropolymers, whereas in others, the properties of VICTREX PEEK make it ideally suited to be the primary seal.
