Fluorosint? 500 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 PTFE ? often eliminating fit and clearance problems. 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. Sizes in drop-down menus are in INCHES Applications: Bearings - Seals - Mixers - Pumps - Appliances - Valve seats Fluorosint is Now Available in 5 Grades: Fluorosint? 500 - Exceptional Dimensional Stability for Precise Tolerance Control Fluorosint? 207 - Lowest Coefficient of Friction of all Fluorosint Grades Fluorosint?
