A self-cooling artificial turf system for water retention and evaporation is described. The system includes a synthetic surface comprising an elastic sub-layer having shock absorbing pads, or shock pads, configured to interlock to one another. Individual ones of the shock pads comprise a top surface and a moisture accumulation region defined by an edge having a height taller than the top surface. Synthetic fibers are positioned above the synthetic surface that are in fluid connection with the at least one moisture accumulation region such that the synthetic fibers are able to wick moisture from the at least one moisture accumulation region when the moisture is present. At least a portion of the synthetic fibers are hydrophilic such that the synthetic fibers wick the moisture as it is expelled from the at least one moisture accumulation region, thereby cooling at least the portion of the synthetic surface.

A support layer for supporting an artificial turf assembly. The support layer being formed of a polymeric foam, preferably having a density of between 20 and 70 grams per liter, such as a polyolefin foam; and having an upper side and a lower side, wherein in use the support layer has been placed with the lower side thereof on a base surface and supports, on the upper side thereof, the artificial turf assembly, the support layer including a plurality of through drainage holes extending from the upper side to the lower side for allowing liquid such as rain water to flow via the plurality of drainage holes from the upper side to the lower side, and also including a plurality of channels at the lower side for allowing liquid such as rain water to flow through the channels along the lower side, wherein each of said plurality of drainage holes debouches into one of the plurality of channels. The support layer is further included in an artificial turf system, that includes an artificial turf assembly with the support layer supported on a base surface such as a layer of sand, wherein the support layer forms, at the upper sides thereof, a closed support surface supporting the artificial turf assembly.

A method of manufacturing an artificial turf includes creating fluid polyurethane mass. The creation including reacting first and second polyols with an isocyanate. The first polyol is a polyether polyol and/or a polyester polyol having at least 2 hydroxyl groups per molecule, the second polyol being polybutadien diol. The isocyanate including isocyanate monomers, isocyanate polymers or isocyanate prepolymers or a mixture thereof, the isocyanate monomers, isocyanate polymers and the isocyanate prepolymers having two or more isocyanate groups per molecule. The method further includes incorporating an artificial turf fiber into a carrier such that a first portion of the fiber protrudes to the front side of the carrier and that a second portion of the fiber is located at the back side of the carrier, adding the fluid polyurethane mass on the back side of the carrier, and hardening the fluid polyurethane mass.

A system and method for processing an artificial turf, and a product produced by the method, is provided. The method includes providing an artificial turf having an infill, separating at least a portion of the infill from the artificial turf, downsizing the artificial turf into artificial turf fragments and rotationally mixing and translating, by a melt system, the artificial turf fragments at a pressure less than a maximum predefined pressure to form a melt. The maximum predefined pressure is between about 0.08 - 20 bar.
