Fluorosint 500

Fluorosint 500 Overview

What is the Material: Fluorosint 500 is a semi-crystalline material and it is a modified PTFE (Teflon) filled with synthetic mica.

Key Material Features: This material is beneficial in applications requiring  dimensional stability, low friction, chemical resistance, and wear resistance.

Other Considerations: Useful in applications where you need greater dimensional stability, hardness, and wear than other PTFE materials.
