Fluorosint ® is a proprietary mixture in which synthetically manufactured mica is chemically linked to PolyTetraFluoroEthylene (PTFE). This bonding results in properties not normally attainable in reinforced PTFE. Fluorosint ® grades offer an excellent combination of low frictional properties and dimensional stability. Fluorosint ® is produced only by Quadrant DSM Engineering Plastic Products.

Exceptional Dimensional Stability for Precise Tolerance Control

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 a 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. The synthetic mica developed and manufactured by Quadrant delivers tolerance performance approximating that of aluminum.
