First of all, we should understand why to use artificial grass infill (quartz sand, crumb rubber, or both):
1.Infill provides a structure for the artificial grass fibers, helping the fibers to stand. The fibers of an artificial turf naturally lay “flat” without the infill material if the artificial grass has no frizzy fibers in the root. For most products, even the artificial grass with thatch can not stand very well without infill.
2.Infill provides a “cushion” effect when stepping over the turf. This protects the roots of the fibers and at the same time adding resilience to the whole artificial turf system. Normally infilled artificial grass system could take more traffic than a non-infill artificial grass system under the same condition.
3.Infill protects the primary backing from UV exposure. For the traditional football turf, or artificial grass with thatch but pile less than 30mm, the yarn can not cover the primary backing completely. Infill protects the primary backing from UV exposure and it helps to extend the useful life of your artificial grass product.
