Rubber granules for artificial turf filling, EPDM granules, and TPE granules are commonly used in the mainstream. EPDM particles, the main component is EPDM rubber. EPDM rubber is a copolymer of ethylene, propylene, and a small amount of non-conjugated diene, which is a kind of ethylene-propylene rubber. EPDM rubber can resist ultraviolet radiation and general chemical reaction with its excellent performance, appropriate elasticity, good shock absorption performance, safety, and comfort. It can protect joints and ligaments and reduce the risk of injury. EPDM rubber granules are odorless, non-toxic, and environmentally friendly products. They are added with anti-mildew and antibacterial raw materials. They are non-flammable, stable and durable, anti-aging and resistant to acid rain, damp heat, and ozone, and are not easy to breed microorganisms. TPE particle is a new type of thermoplastic elastomer particle. Its raw material is a blend of the hydrogenated styrene-butadiene block copolymer, high polymer of ethylene and butene (POE), and other environmentally friendly polymer materials with excellent performance. It has the characteristics of high elasticity, wear resistance and anti-aging performance, high and low-temperature resistance, excellent sports performance, and environmental protection performance. It is a new high-quality auxiliary filler approved by FIFA artificial turf. An appropriate amount of rubber particles with high elastic properties are filled so that the artificial turf can effectively simulate the hardness of the soil ground, improve the surface elasticity and impact resistance of the artificial turf field, and prevent and reduce the damage caused by collision during the exercise process.
About the selection specification and filling ratio of filling materials
When artificial turf is filled with auxiliary materials, it is necessary to select qualified auxiliary materials according to the different types of sites and fill them in the correct proportion. If the field is filled randomly and blindly, not only will it not improve the sports performance of the artificial turf sports field, it may also reduce the service life of the field and cause injuries to players. In order to meet the mechanical properties of the court and at the same time play a role in protecting the athletes, it is necessary to purchase and fill in accordance with the specified standards.
The selection of quartz sand should be based on the following criteria: 1. The particle material is excellent, and the commonly used specifications are 40-60 mesh. In the actual construction of artificial turf sites, quartz sand with different specifications and meshes should be selected according to the type of site; 2. Particles are Uniform and round without sharp edges and corners, and the roundness is not less than 80%; 3. The surface of quartz sand is clean without dust and cracks, and has strong wear resistance and corrosion resistance; 4. The moisture content is less than 1‰.
