Disclosed is a three-dimensionally entangled elastomeric thermoplastic polymer extruded filament or fibre mat for a shockpad for an artificial turf system that provides improved shock absorption and/or energy restitution characteristics, especially over a prolonged period of time. The mat comprises a entangled mat of extruded filaments made from a thermoplastic elastomeric polyester, polyether or polyurethane polymer. A shockpad for artificial turf systems comprising a three-dimensional entangled mat of extruded filaments is also claimed. The shockpad also comprises one or more additional layers, each of the additional layers being a film, a layer of woven or nonwoven fibrous material, a two-dimensional grid or scrim, or a three-dimensional entangled mat of extruded filaments. An artificial turf system is also claimed, comprising a backing fabric, the backing fabric being tufted with at least one type of synthetic grass halms and coated to lock the tufted synthetic grass halms into place, and a shock absorbing layer of a shockpad with a three-dimensional entangled mat of extruded filaments. |
