At National Fluoromers, we offer high-performance Copper and Nickel Filled PTFE materials engineered for applications that demand a balance of chemical resistance, thermal endurance, mechanical strength, and electrical conductivity. These specialty-filled compounds are ideal for EMI shielding, conductive seals, laboratory applications, and cleanroom systems.

By incorporating copper or nickel powders into PTFE, this grade enhances PTFE’s structural integrity while introducing antistatic, shielding, or conductive properties.

What is Copper/Nickel Filled PTFE?

Copper Filled PTFE and Nickel Filled PTFE are composites made by blending virgin PTFE resin with controlled percentages of either copper or nickel powders. These metals enhance the base material's thermal conductivity, EMI/RFI shielding capacity, and dimensional control, while still offering the non-stick, low-friction, and corrosion-resistant properties of PTFE.

Nickel-filled PTFE is often preferred in high-purity or aggressive environments where copper may not be suitable.
