Term commonly used to indicate the rubber granules which are strewed between the artificial turf fibres. This term also include the sand layer.



Stands for Styrene-Butadiene-Rubber. In the artificial turf industry this is a collective noun for infill materials derived from post-consumer grinded tires. The granulates from recycled tires of cars, trucks, tractors and earth movers do not only contain SBR rubber but also many other rubber types and other chemicals. 



Abbreviation for Ethylene-Propylene-Diene Rubber. This was the first alternative to “SBR” material. The EPDM infill can be specially produced from virgin raw materials or, alternatively, it can be obtained from grinded production scraps (seals and other parts).

Because of its stability to UV and good resistance to oxidation EPDM is appropriate for outdoor applications.

EPDM is a thermoset rubber, which means that it has undergone a process called cross-linking, by which its molecules have been irreversibly bound together. This process prevents any further reuse of EPDM,  which is not recyclable but by grinding.



Abbreviation for Thermoplastic Elastomer. Thermoplastic Elastomers are made from an elastic phase, which confers the typical rubber properties and by a plastic phase which determines their recyclability and processing ease.


This makes possible to produce the infill granules in a specific shape and size which are ideal for their use.

Another important point is that TPEs can be reused several times by heating the material to the melting point.
