Fluorosint® (Mica-Filled PTFE)
Fluorosint® is a mica-filled PTFE material engineered to improve dimensional stability, wear resistance, and creep performance compared to virgin PTFE. It retains the chemical resistance and low friction of PTFE while offering tighter tolerances and improved mechanical properties.
Fluorosint® components are produced through compression molding and precision machining for high-performance applications.
