FLUOROSINT (Mica Filled PTFE) 500

For many end users, the mechanical and thermal properties of PTFE need to be improved and ideally this should be achieved without impairing the unique chemical, electrical and frictional properties of the material. This has been achieved by Quadrant EPP UK Ltd by incorporating Mica flakes into PTFE. The outstanding combination of properties in Fluorosint has meant its acceptance as a leading engineering plastic material.

It offers continuous service at temperatures between -260°C and +260°C and even higher for limited periods. As a guide, Fluorosint should be used wherever PTFE would normally be considered but where greater hardness, better creep resistance at elevated temperatures and a much lower wear rate are essential. The coefficient of linear expansion of Fluorosint is less than one-third that of unfilled PTFE and consequently, components such as bearings and valve seats remain more firmly seated during thermal cycling and lower clearances. Chemical resistance and electrical properties are outstanding. Fluorosint is unaffected by almost every commercially used chemical and solvent.
