Milled glass fibers have the least effect on chemical and electrical properties and add greatly to the mechanical properties of unfilled PTFE. Addition of glass improves compressive properties by as much as 40% and improves wear resistance greatly. These compounds resist acids and oxidation but can be attacked by alkali.
Graphite has good chemical resistance to corrosive environments and exhibits good initial wear and rubbing/sliding characteristics in dry and water applications. Commonly blended with carbon and PTFE.

25% Bronze 40% Bronze 60% Bronze
This filler has better wear, creep resistance, and higher thermal conductivity than glass fiber with PTFE. The compound is easily machined, but has poor chemical resistance in the presence of acids and alkali. Useful in applications which undergo high mechanical loads or high-speed rubbing contacts where the bronze filler supplies the strength and conductivity to carry away excess, unwanted heat.

5% Molybdenum Disulfide
This filler is used frequently in combination with others to increase surface hardness, stiffness, and to reduce the starting coefficient of friction and steady-state wear. Its effect on electrical and chemical properties is negligible.
Carbon has good chemical resistance to corrosive environments. It exhibits good initial wear and rubbing or sliding contact characteristics, both dry and water applications. It is frequently used in piston rings to reduce cylinder wall wear by entrapping abrasive foreign particles in their relatively soft surfaces.
