Who am I ?
Name this Plastic: I am an advanced polymer material that has nine times greater resistance to deformation under load than unfilled PTFE, a coefficient of linear thermal expansion that approaches the expansion rate of aluminum, and is also non-abrasive to most mating materials. Who am I?
Fluorosint® 500 PTFE
Fluorosint® 500 PTFE 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 virgin PTFE -- often eliminating fit and clearance problems (see Figure 20). It is 1/3 harder than virgin PTFE, has better wear characteristics and maintains low frictional properties. Fluorosint® 500 PTFE is also non-abrasive to most mating materials.
- Chemical resistance parallels PTFE
- Continuous use temperatures to 500°F (260°C)
- higher load carrying capability compared to PTFE
- 1/9 of the deformation under load to PTFE
- lower coefficient of thermal expansion than PTFE
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.
