Material Data Sheet
Material: Fluorosint® 500
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.
