Friction and Wear Performance
This material offers a low friction coefficient, as PTFE significantly reduces surface friction and provides excellent self-lubrication. At the same time, it maintains outstanding wear resistance, resulting in a very low wear rate and extended service life. It is commonly used in sliding components such as oil-free bearings, sliding rails, and guide rails.

Mechanical Properties
The material retains the high strength and stiffness typical of PA66 engineering plastics, allowing it to withstand relatively high loads. The addition of MoS₂ also enhances thermal stability, improving dimensional stability and heat resistance under elevated temperatures. Typical applications include load-bearing components such as mechanical cams, oilfield equipment parts, automotive engine fans, and filter components.

Comprehensive Performance
It exhibits good dimensional stability due to relatively low moisture absorption and shrinkage, ensuring reliable precision in complex environments. In addition, it has strong resistance to a wide range of chemicals, solvents, and oils. This makes it suitable for precision transmission parts such as gears (including motor and instrument gears) and bearing cages, as well as industrial components like textile machinery parts (e.g., shuttles and yarn guides) and internal components in office automation equipment.

Technical Insight and Application Notes
The material benefits from a synergistic effect: PA66 provides the fundamental strength and heat resistance, while MoS₂ and PTFE function as solid lubricants. PTFE forms a transfer film on contact surfaces to reduce friction, whereas MoS₂ improves hardness and wear resistance. This combination makes the material particularly effective in high-speed, high-load, or maintenance-difficult applications.

In terms of processing, this modified material is typically manufactured using injection molding. Since PA66 is hygroscopic, it must be thoroughly dried before processing (for example, at 100°C for approximately 4 hours) to prevent defects such as bubbles or material degradation, thereby ensuring optimal final performance.
