Enhanced PTFE

Unique formulation of co-deposited electroless nickel with PTFE meeting AMS 2454

Anoplate’s ENhanced PTFE coatings offer the uniform deposition and hardness of electroless nickel, enhanced with the lubricity and release characteristics of a PTFE fluorocarbon.

ENhanced PTFE coatings are selected for their effectiveness in reducing downtime and extending equipment life, and for their ability to optimize process and equipment performance.

Unlike immersion or spray PTFE coatings which are have heavy and inconsistent thickness, Anoplate’s ENhanced PTFE deposits uniformly on all surfaces and with controlled thickness. ENhanced PTFE evenly distributes the PTFE particles throughout the thickness of the coating, so the coating will perform consistently throughout its wear life.

Applications

Valves used in fluid delivery
Pump rotors
External fixation devices
Mold & die cores and cavities
Composite Molds and layout fixtures

Key Considerations

Anoplate’s ENhanced PTFE provides extended lubrication of moving, wear-prone, high-precision and inaccessible parts. It provides lubricity for parts exposed to solvents, working in cryogenic temperatures, or operating in environments with unconventional lubricants.

Durable, versatile ENhanced PTFE coatings can be applied to nearly any metallic substrate material. Coating thickness can range from 0.0001 – 0.0005”. Depending on the application, Anoplate can apply thicker coatings using an electroless nickel underplate selected for extending performance conditions in severe applications.

ENhanced PTFE meets and exceeds the requirements of the following:

AMS 2454
Code T of MIL-DTL-38999
