Fluorosint® 500 Enhanced PTFE offers an ideal combination of stability and wear resistance for sealing applications where tight dimensional control is required. Fluorosint® 500 also greatly reduces the risk of catastrophic system failure by becoming a sacrificial wear surface. With a deformation under load 9 times lower than virgin PTFE, Fluorosint® 500 allows designers to greatly improve the efficiency of systems without sacrificing the wear resistance and forgiving benefits of PTFE.
Fluorosint® 500 PTFE 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 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.
