Electroless Nickel PTFE - Food Grade Teflon Coating

Food-Grade, Low-Friction Coating for Demanding Applications

Electroless Nickel PTFE—also known as Nye-Tef™—is a proprietary, food-grade composite coating developed exclusively by Electro-Coatings. Engineered for exceptional corrosion resistance, low friction, and superior coating adhesion, Nye-Tef™ is a trusted solution for critical components used in food processing, high-performance manufacturing, and chemically aggressive environments.

This advanced surface treatment combines the self-lubricating properties of PTFE (Teflon™) with the high wear resistance and durability of electroless nickel, creating a uniform, high-performance barrier that outperforms conventional plating or lubrication methods.

Nye-Tef™ combines the self-lubricating properties of PTFE with the high wear resistant hardness of electroless nickel, and has excellent adhesion which allows for an increased control on uniform thickness. The PTFE coatings self-lubricating properties make it an ideal surface treatment for components and assemblies that cannot use conventional lubricants.

The PTFE in the plated layer provides excellent release from calcium found in hard water areas. In combination with the corrosion resistance of the layer, it offers a solution to the age-old problem of scale build-up on heating elements and sprays nozzles.

Key Properties for Nickel PTFE Coating

Low Coefficient of Friction: PTFE is one of the world’s most friction-free materials. Integrated into the nickel matrix, it enables smooth, self-lubricating performance in dry and wet conditions.
Exceptional Wear Resistance: The nickel matrix significantly enhances the abrasion resistance of PTFE, extending part life even under heavy mechanical stress.
Superior Corrosion Resistance: Resistant to moisture, chemicals, and pH extremes—ideal for high-humidity and hard water environments.
Excellent Release Characteristics: Prevents material build-up, especially from calcium deposits in heating elements, spray nozzles, and food-processing systems.
Food Grade & FDA-Compliant Options: Nye-Tef™ is available in certified formulations for direct food contact, with strict quality control and traceable material sources.
Uniform Coating Thickness: Non-electrolytic deposition allows for a highly consistent layer—documented accuracy to ±10%—over complex shapes and internal features.
Strong Adhesion: Superior bonding even on hard-to-plate substrates like titanium and stainless steel.

Typical Applications for Electroless Nickel with PTFE

Nye-Tef™ is used in applications where traditional lubricants cannot be applied, or where friction and corrosion must be simultaneously controlled:

Food processing equipment
Sorting and conveying systems
Injection molds and extrusion dies
Pump rotors and impellers
Heating elements (resists scale buildup)
Titanium bearings and high-wear mechanical parts
Spray nozzles, blenders, and packaging machines

What Is Nye-Tef™ (Electroless Nickel PTFE)?

Nye-Tef™ is a composite coating in which submicronic PTFE particles are suspended within a nickel-phosphorus alloy and applied through an autocatalytic chemical process. Unlike standard electroplating, this method deposits an even, highly adhesive layer of material over the entire surface of the part—including internal cavities and complex geometries.

Once deposited, the PTFE provides continuous low-friction performance, while the nickel layer delivers a hardness of up to 50 Rc, excellent chemical resistance, and long-term wear protection. The result is a coating solution that functions exceptionally well in environments where lubrication is not possible or scale buildup is a concern.

Why Choose Nye-Tef™?

Many coatings claim low friction, but few can match the performance of PTFE embedded in a wear-resistant nickel alloy. What makes Nye-Tef™ unique is its ability to maintain consistent release and corrosion protection over a long operational life—even in harsh or sanitary-critical environments.

Our coating chemists and process engineers have decades of hands-on experience in tailoring the Nye-Tef™ process to match your part geometry, functional requirements, and industry regulations. We also offer full technical support, including coating specification guidance, masking options, and test validation.

The coating chemists and application experts who developed Nye-Tef™ will gladly offer full information and applications advice on its effective use. Contact us to experience our "Yes We Can" spirit on industry's toughest coating challenges.

Electroless Nickel PTFE (Nye-Tef™) Process

Electroless nickel PTFE composite coating consists of an autocatalytic alloy applied nickel/phosphorus matrix containing submicronic particles of PTFE (polytetrafluoroethylene). The PTFE, while soft in its natural form, becomes exceptionally durable when suspended in the nickel matrix. A hardness of 50Rc, combined with the natural friction resistance of Teflon coating, or PTFE, yields a surface that can resist significant abrasion over a long working life.

The coating's non-crystalline molecular structure adds resistance to corrosion and wears due to abrasion. The use of electroless nickel with the ptfe coating surface delivers a coating with excellent adhesion and extremely uniform coating thickness. Documented accuracy to +/- 10% ensures consistent coverage. The non-electrolytic application technology of Nye-Tef™ provides a completely uniform coating, including full coverage of hidden surfaces or intricate geometries.
