Reinforced Polytetrafluorethylene(PTFE)
FLUOROSINT’s unique properties are the result of a proprietary process in which synthetically manufactured mica is chemically linked to PTFE. This bonding results into a load carrying capability and thermal expansion rate not normally attainable in reinforced PTFE. The chemical and temperature resistance inherent in PTFE are practically retained.
Main characteristics:
• Very high max. allowable service temperature in air (continuously 260 C)
• Excellent chemical and hydrolysis resistance
• Good wear resistance
• Low coefficient of friction
• Very good dimensional stability
• Physiologically inert (only applies to FLUOROSINT 207)
• Good electrical insulating properties
• Outstanding UV-and weather resistance
• Inherent low flammability
We distinguish two different formulations:
FLUOROSINT 500(PTFE + mica)(ivory)
FLUOROSINT 500 has nine times greater resistance to deformation under load than unfilled PTFE (tested according to ASTM D 621; stress of 14 MPa at 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 wear characteristics and maintains low frictional properties. FLUOROSINT 500 is also non abrasive to most mating materials.
