Reinforced with a proprietary synthetic mica, this material exhibits, in addition to its inherent outstanding chemical and hydrolysis resistance, very good mechanical and tribological properties.
Fluorosint 500 PTFE (colour: ivory) has nine times greater resistance to deformation under load than unfilled PTFE. Its coefficient of linear thermal expansion approaches the expansion rate of aluminum and is 1/5 that of virgin PTFE, often eliminating fit and clearance problems. It is considerably harder than virgin PTFE, has better wear characteristics and maintains low frictional properties. Fluorosint 500 PTFE is also non-abrasive to most mating materials.
Fluorosint enhanced PTFE’s unique properties are the result of a proprietary process in which synthetically manufactured mica is chemically linked to virgin 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.
Due to its unique PTFE matrix, Fluorosint's physical strength characteristics are not as high as other advanced engineering plastics profiled here such as Ketron® PEEK or Duratron® PAI (formerly Torlon® PAI). This compliance/ductility makes it ideal for seats and seals
Abradable seals in turbomachinery fabricated from Fluorosint® 500 PTFE tubular bar reliably perform in hostile chemical environments while providing dramatic efficiency gains. (Prior materials: Aluminum, Bronze, Babbit)
Europe's premier automobile manufacturers choose Fluorosint® 500 PTFE over other filled PTFE for improved performance and service life capabilities. (Prior material: GF PTFE)
