Reinforced with a synthetic mica, this material exhibits, in addition to its excellent chemical resistance and hydrolysis, excellent mechanical and tribological properties. Fluorosint® 500 has nine times greater resistance to deformation under load than PTFE. Its coefficient of linear thermal expansion approximates the expansion rate of aluminum and is 1/4 of the virgin PTFE. Fluorosint® 500 reinforced PTFE offers an ideal combination of stability and wear resistance for sealing applications where excellent dimensional stability is required.
