Which is the most suitable filler material for artificial turf?
Nov 18, 2018

The choice of filling materials has an important bearing on the final use of artificial turf. Only the selection of suitable filling materials can guarantee the quality of artificial turf.

The filling material of the artificial turf is generally sand or rubber granules, and sometimes the two are mixed. When used in combination, the ratio of the two is determined according to the specific conditions, and the usual mixing ratio is 70% rubber granules + 30% sand.

In the past, 100% sand was used as a filling material in order to increase the stability of the base of the lawn. However, with the maturity of the artificial turf manufacturing process, the basic manufacturing is relatively perfect, so in the past, sand was used to stabilize the lawn. It has gradually been eliminated, and now more used filling methods are 100% rubber particles.


The filled sand or rubber particles are mostly medium in size and must be washed before filling. For some sports with high impact strength, such as football and football, the proportion of rubber particles should be appropriately increased to minimize the damage of athletes. For sports venues with little or no impact, such as tennis courts, as long as the hardness of the site is uniform, the cushioning requirements are not high, so there is a large margin in the choice of filler materials.


The filling depth of the quartz sand or rubber particles in the artificial turf may depend on the purpose of use and the height of the selected lawn beam.

For sports with high impact strength, artificial turf with long leaf bundles can be selected and filled with deeper filling. Generally, the suitable filling depth of the artificial soccer field lawn is 5 mm from the tip of the blade. For sports that require high flatness and uniformity, such as hockey, the leaf bundle can be appropriately reduced, the filling depth can be increased, and even the lawn surface can be level.


Studies have shown that on the artificial football field lawn, the rebound of the football and the surface hardness of the court can be controlled to some extent by the type of filling and the depth of filling. In short, in the construction of artificial turf, all factors should be fully combined, relying on technology to maximize the economic and application of artificial turf.
