For artificial grass products, filler is an important component and plays a very important role. In addition to protecting grass silk and stabilizing the lawn, it can also provide the corresponding performance required by the playing field (friction coefficient, buffer performance, rotational resistance, etc.), making the lawn closer to natural lawn in use. With the development of the industry, there are more and more types of artificial grass fillers, and people's requirements for fillers are getting higher and higher. People's attention is no longer limited to performance, but also pays more attention to environmental protection and health.
At present, the types of fillers are roughly divided into quartz sand, SBR rubber particles, EPDM particles, TPE/TPO/PE particles, and organic particles. Among them, SBR rubber particles, EPDM particles, TPE/TPO/PE particles, and organic particles belong to Elastic functional granules, these types of products have their own advantages and disadvantages, and I will give you a brief introduction below.
1. As the most common filler, quartz sand has obvious advantages and disadvantages. The price is cheap, the market supply is large, basically you can buy it anywhere, and its water permeability is very good. At the same time, its texture is very hard. During use, it is not only easy to wear grass silk, but also easy to scratch the skin of athletes, so don't think about buying it. The kneeling after the ball is celebrated. Now when artificial grass is filled with quartz sand, most of the upper layer will be paved with a layer of other types of elastic functional filling particles to ensure both cost and performance.
2. SBR rubber granules are also traditional filler granules, which are basically made of recycled waste tires, etc., with low price and cost, perfect elasticity and durability, and excellent UV and weather resistance. One of the largest amount of filler particles in the world; although there is no clear report in the world whether SBR rubber particles are really harmful to the health of players, but its uncontrollable source and its pungent smell (especially in summer hot weather) make It is difficult for people to associate it with the word "environmental protection".
3. EPDM (Ethylene propylenediene monomer, tertiary ethylene propylene rubber) particles, originally a kind of elastomer particles used in plastic track, but its excellent elastic properties are also very suitable for use as fillers. In recent years, it has been used as SBR The "environmentally friendly alternative" of granules is in use. It has no irritating odor, uniform particle size distribution, and good paving performance. Unlike SBR granules, which only have black options, EPDM granules can be made into the color you want. However, the anti-UV and anti-aging performance of EPDM is average. In terms of price, it is much more expensive than SBR particles, and qualified EPDM products have higher requirements for their glue content. EPDM particles with low glue content not only have a limited service life impact, and it is easy to harden. EPDM particles can be produced from new materials or recycled. This has caused the quality of EPDM particles on the market to vary, and you may need to consider carefully.
4. TPE/TPO particles are all thermoplastic elastomers, and their basic properties are basically the same as EPDM. They have no irritating odor, uniform particle size distribution, and changeable colors. The difference is that TPE/TPO particles also have recyclable properties. , similarly, its price and cost are high, its weather resistance is average, and it also has requirements for the amount of glue contained. Moreover, as a new type of filler product, there is not yet a large amount of stable supply on the market.
5. At present, there is another kind of organic particles in the filler market, which is composed of pure natural wood chips. Its composition is pure natural, with good anti-UV aging resistance and corrosion resistance, low density, no irritating smell, and cooling performance; but This kind of product has poor sports performance, not only is it expensive, but also requires additional maintenance costs. Due to its low density, it is easily washed away in heavy rain, and it is a relatively seldom used filler product at present.
