PTFE + Mica 500
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 characteristics and maintains low frictional properties. FLUOROSINT 500 is also non-abrasive to most mating materials.
Profile
- 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
Applications
- Labyrinth seals and shrouds
- Abradable seals in turbomachinery fabricated from FluorosintŪ 500 tubular bar perform reliably in hostile chemical environments while providing dramatic efficiency gains.
- Dishwasher arm bearing
- These bearings made of FluorosintŪ 207 offer a 20 year service life, and FDA compliance.
- Transmission and Power Steering Seal Rings
- Europe's premier automobile manufacturers choose FluorosintŪ 500 over other filled PTFE for improved performance and service life capabilities.
- Valve seats
- Seats fabricated from FluorosintŪ 207 excel in steam and hot air service due to their non-permeability, excellent dimensional stability and low wear rate.
