Material Information

Fluorosint® is the result of synthetically manufactured mica that has been chemically linked to PTFE. While Fluorosint®’s chemical resistance parallels PTFE, Fluorosint®’s unique chemical composition results in properties not normally attainable in PTFE such as better wear resistance and a lower coefficient of thermal expansion. It has continuous use temperatures up to 500º F. Fluorosint® in general offers low frictional properties and dimensional stability. Fluorosint® 207 PTFE is unique in that it offers the lowest coefficient of friction in the Fluorosint® grades, has unmatched dimensional stability, has excellent creep resistance, and is FDA approved. It is also non-permeable to steam and works well against most mating surfaces. Compared to unfilled PTFE, Fluorosint® 207 PTFE has 1/20th the rate of wear of PTFE below 300º F. This makes it ideal for use as aggressive service bearings and bushings or as a replacement for applications using PTFE that require a longer lasting material. It is available in a white color in the form of rod or plate.
