Modified VICTREX PEEK
AF805 is specifically designed for valve seats allowing higher ball interference pressure with reduced ball torque factor

AF805 is a modified VICTREX PEEK material with special fillers.

Formulated to give greater flexibility than standard VICTREX PEEK materials and a much lower coefficient of friction. AF805 retains the essential properties of VICTREX PEEK being a semi-crystalline very high performance engineering thermoplastic designed for extremely demanding applications.
