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.
*Fluorosint® 500* has nine times greater resistance to deformation under load than unfilled PTFE (see Figure 19). Its coefficient of linear thermal expansion approaches the expansion rate of aluminum, and is 1/5 that of PTFE — often eliminating fit and clearance problems (see Figure 20). It is 1/3 harder than PTFE, has better wear characteristics and maintains low frictional properties. Fluorosint® 500 is also non-abrasive to most mating materials.
*Fluorosint® 207* has unmatched dimensional stability, excellent creep resistance and white color uniquely position this material to serve FDA regulated applications. It is non-permeable in steam and complies with the FDA’s regulation 21 CFR 175.300. Its relative wear rate is 1/20 the rate of PTFE below 300°F (150°C) making it an excellent choice for aggressive service bearings and bushings.

_Notes: Due to its PTFE matrix, Fluorosint’s physical strength
characteristics are not as high as other advanced engineering plastics._
