Continuous use temperatures to 500°F (260°C). Fluorosint’s unique properties are the result of a proprietary process in which synthetically manufactured mica is chemically linked to
PTFE.
This bonding results in properties not normally attainable in reinforced PTFE. Fluorosint grades offer an excellent combination of low frictional properties and dimensional stability.
Synthetic Mica filled.
Fluorosint 500 has nine times greater
resistance to deformation under load than unfilled PTFE (tested according to
ASTM D 621; stress of 14 MPa of 50°C). Its coefficient of linear thermal
expansion approaches the expansion rate of aluminium and is 1/5 that of virgin
PTFE. It is considerably harder than virgin PTFE, has better wear
characteristics and maintains low frictional properties. Fluorosint 500 is also
non-abrasive to most mating materials.
