National Fluoromers offers top-quality Bronze Filled PTFE, designed to meet the performance needs of high-speed, high-load, and high-temperature systems. By adding up to 40% finely powdered bronze to virgin PTFE, we produce a composite material with vastly improved mechanical strength, thermal conductivity, and dimensional stability — without compromising PTFE’s inherent chemical resistance and low-friction characteristics.

Bronze Filled PTFE is the go-to solution for bearing elements, piston rings, seals, and guide components in dynamic mechanical systems.

What is Bronze Filled PTFE?

Bronze Filled PTFE is a reinforced PTFE compound incorporating bronze particles to boost strength, reduce wear, and enhance heat dissipation. The bronze content gives it a distinctive golden brown color and makes it more rigid and thermally conductive than unfilled PTFE.

This formulation is ideal for moving parts that endure high mechanical loads, frequent motion, and continuous operation.
