What makes Fluorosint™ stand apart from ordinary polytetrafluoroethylene (PTFE) blends? It starts with a unique filler—synthetic mica—and how Mitsubishi Chemical Group (MCG) uses it.
What is Synthetic Mica?
Synthetic mica (fluorphlogopite) is a man-made mineral with a smoother, more consistent structure than natural mica. This texture can provide benefits in plastics, paints, and even cosmetics.
In Fluorosint™, synthetic mica plays a critical role by:
- Reinforcing the PTFE base with greater hardness than natural mica
- Lowering the coefficient of linear thermal expansion (CLTE) to improve dimensional stability
- Enabling high strength and wear resistance when fully bonded
Why Does MCG Make It In-House?
Instead of sourcing synthetic mica to save on costs and hassle, MCG makes our own to give you more consistent, higher-performing enhanced PTFE. In-house control and over five decades of compounding experience means better quality, cleaner surfaces, and stronger compatibility with PTFE. The result?

Not All “Mica-Filled PTFE” Is Equal
When another supplier says their product is “just like Fluorosint™,” ask for the data. You’ll see the difference in:
Strength |
Wear Resistance |
Thermal Stability |
