VICTREX PEEK material is a semi-crystalline thermoplastic typically used as a replacement for machined metals in a wide variety of high performance end-use applications.
KEY PROPERTIES
Possible Applications
VICTREX PEEK is a high performance thermoplastic material with outstanding mechanical, thermal and chemical resistance properties, which makes it ideal for sealing applications. In some industries, VICTREX PEEK seals are often used as a mechanical backup for softer materials, and in other industries the unique properties of VICTREX PEEK make it suitable to be the primary seal.
Critically, VICTREX PEEK not only can withstand high temperatures, but does so in harsh chemical environments which have made it the material of choice for some applications in the oil and gas sector.
Other applications include:
Valve seats, bearing cages, backup rings, end-caps, flowmeters, frac balls, insulators.
