1. Composition:
- Made from polyurethane prepolymers, mixed polymers, and rubber granules.
- Typically consists of multiple layers, including a base layer, a cushioning layer, and a surface layer.
2. Performance Characteristics:
- Elasticity and Comfort: Offers excellent elasticity, providing a comfortable running surface that minimizes the risk of injuries.
- Durability: Highly durable and resistant to wear, making it suitable for high-intensity and frequent use.
- Weather Resistance: Resistant to high and low temperatures, as well as UV radiation, ensuring longevity.
- Environmental Impact: Modern polyurethane tracks are often made from eco-friendly materials, though the manufacturing process involves chemicals like TDI and MDI, which can be harmful.
3. Construction and Maintenance:
- Installation: Requires on-site pouring and curing, which can be time-consuming and requires specialized equipment.
- Maintenance: Generally low maintenance due to its durability, but difficult to recycle or dispose of after its lifespan.
4. Applications:
- Ideal for professional sports fields, school tracks, and athletic stadiums.
