A full-PU synthetic track is a high-performance track made entirely of pure polyurethane (PU) material, without the use of rubber granules as a filler. Its structure typically consists of multiple layers of polyurethane coating, providing a smooth surface, excellent elasticity, and strong wear resistance, with superior anti-slip and shock-absorbing properties. Full-PU tracks are highly resistant to aging and weathering, capable of withstanding long-term exposure to sunlight, rain, and heavy use, making them ideal for professional sports stadiums and large competition venues where high track standards are required. While offering excellent durability and a premium athletic experience, full-PU tracks are generally more expensive compared to other types.
