Engineered to Slide — The Self-Lubricating Alloy That Outperforms Metal Bushings
Material Overview
PA/PTFE is one of the most specialized polymer alloys in the engineering plastics universe. By dispersing polytetrafluoroethylene microparticles uniformly throughout a polyamide matrix, this alloy achieves a friction coefficient and wear rate approaching lubricated metal bearings — without ever needing external lubrication.
For maintenance-free dynamic equipment, food-contact-clean machinery, and chemical-resistant moving parts, PA/PTFE replaces components that traditionally required bronze or oil-impregnated metal solutions. Renhong’s compounding technology ensures uniform PTFE dispersion at the micron scale — the difference between a bushing surviving 1,000 hours of dynamic service and one lasting 50,000.
Key Features
⚙️ Low Friction Coefficient
Dynamic friction coefficient as low as 0.10–0.15 against steel — comparable to lubricated bearings.
🛡️ Strong Wear Resistance
Wear factor (K) reduced by 80–90% compared to unfilled nylon, extending part life in dynamic applications.
🧪 Excellent Chemical Resistance
PTFE phase provides resistance to aggressive chemicals, fuels, and process fluids that attack pure nylon.
🔥 Wide Service Temperature
Continuous use temperature up to 100°C, with PTFE-stabilized performance from –40°C upward.
💧 Self-Lubricating in Service
No external lubrication required — suitable for maintenance-free equipment and food-contact-clean designs.
