Resources Unity has developed a Nano Polyurethane Technology that provides significant benefits over conventional polymer materials. The key to this technique is an improvement in the connection of the molecular chains in its structure, which has resulted in a significant decline in failure at the micro-structure level of the polymer material. This has extended the reliability and longevity of the material, making it more durable and long-lasting. Resources Unity’s unique technology has pushed the boundaries of material application and value proposition, marking another breakthrough in the industry.

Test Environment | (10% AFS 50-70 Silica Sands, 2 hours, Relative Erosion Resistance) (higher parameter equals better wear performance) | |
Test Environment (Temperature) | Room Temperature | At 45˚C |

The tests are evaluated using the Slurry Jet Erosion testing method, which is conducted in a slurry mixture with 10% 36 mesh angular SiC particles for 4 hours with a 20-degree impingement angle. Volume loss in mm3 is the metric used to assess wear performance, with lower values indicating superior wear resistance.
Testing at room temperature and 45°C and 60°C elevations revealed that carbon steel has poor wear resistance with a volume loss of 231 mm3 across all test settings. In contrast, nano-polyurethane has superior wear resistance, with volume loss values of 21.9 mm3, 6.8 mm3, and 5.6 mm3 for the test settings at ambient temperature, 45 °C, and 60 °C.

Test Results
We at Recourses Unity measured the weight loss of five different materials in mg/100 cycles. The research found that nano-polyurethane had the best wear resistance, with the lowest weight loss value of 28.5 mg/100 cycles. The weight loss of common polyurethane, which is more than double that of nano-polyurethane, was 62 mg/100 cycles. As a result of its low wear resistance, Nature rubber had the highest weight loss value (423 mg/100 cycles), followed by AR steel plate (476 mg/100 cycles). A weight loss value of 80 mg/100 cycles for UHMW polyethylene and a weight loss value of 176 mg/100 cycles for Linear Polyethylene indicate that both materials have moderate wear resistance.

Key Advantages
- Better Wear Performance: Nanoparticles can improve the wear resistance of polyurethane, reducing the need for frequent replacements and repairs and saving time and money.
- Low Coefficient of Friction: Nano Polyurethane materials have a low coefficient of friction, meaning they slide or move easily against other surfaces. It makes them ideal for applications where low friction is important.
- Energy cost savings: Nano polyurethane technology can minimize energy consumption by increasing equipment efficiency and decreasing frictional losses, resulting in considerable long-term cost reductions.
- Anti-aging: Nano Polyurethane technology can improve the aging properties of polyurethane materials, making them more resistant to degradation and extending their lifespan.
- High strength: Nano Polyurethane materials have improved mechanical properties, making them suitable for high-performance applications.
