Plastic Running Track Granules: A Comprehensive Overview Introduction Plastic running track granules are an essential component of modern athletic tracks. These granules are made of synthetic materials and are designed to provide a durable and safe running surface for athletes. In this article, we will explore the various aspects of plastic running track granules, including their composition, properties, manufacturing process, and applications. Composition Plastic running track granules are made of a variety of synthetic materials, including polyurethane, ethylene propylene diene monomer (EPDM), and styrene-butadiene rubber (SBR). These materials are carefully selected to provide the desired properties of the granules, such as elasticity, durability, and resistance to weathering and UV radiation. Polyurethane is the most commonly used material for plastic running track granules. It is a versatile material that can be formulated to provide a wide range of properties, such as hardness, elasticity, and resistance to abrasion. EPDM is another popular material for running track granules. It is a synthetic rubber that is known for its excellent weathering resistance and UV stability. SBR is a synthetic rubber that is commonly used as a filler material in plastic running track granules. It provides good elasticity and durability, but is less resistant to weathering and UV radiation than other materials. Properties Plastic running track granules have a number of important properties that make them ideal for use in athletic tracks. These properties include: 1. Elasticity: Running track granules must be able to absorb the energy of the athlete's foot strike and then return that energy to the runner as they push off. This requires a high degree of elasticity in the granules. 2. Durability: Running tracks are subjected to a great deal of wear and tear, so the granules must be able to withstand the repeated impact of athletes' feet and the effects of weathering and UV radiation. 3. Slip resistance: Running track granules must provide a surface that is slip-resistant, even when wet. 4. Color stability: Running track granules must maintain their color over time, even when exposed to UV radiation and weathering. 5. Environmental friendliness: Running track granules should be environmentally friendly and non-toxic. Manufacturing process The manufacturing process for plastic running track granules involves several steps. First, the raw materials are mixed together in precise quantities to achieve the desired properties of the granules. The mixture is then heated and extruded into long strands, which are cooled and cut into small pellets. These pellets are then screened to remove any impurities and sorted by size. The final step in the manufacturing process is to add color to the granules. This is done by mixing in pigments or dyes that are resistant to UV radiation and weathering. The colored granules are then packaged and shipped to athletic track manufacturers for use in the construction of running tracks. Applications Plastic running track granules are used in the construction of athletic tracks for a variety of sports, including track and field, soccer, and basketball. They are also used in playgrounds, tennis courts, and other recreational facilities. Conclusion Plastic running track granules are an important component of modern athletic tracks. They provide a durable, slip-resistant, and environmentally friendly surface for athletes to train and compete on. With their excellent properties and manufacturing process, plastic running track granules are sure to remain a popular choice for athletic track construction for years to come.
