POLYMER GRANULES SUITABLE AS INFILL MATERIAL FOR ARTIFICIAL TURF STRUCTURES

摘要

The invention relates to polymer granules suitable as infill material for artificial turf structures wherein the granules have one or more hollow spaces, wherein each hollow space occupies at least 10% of the total volume of a polymer granule. The invention further relates to artificial turf structures comprising a backing sheet with an upper surface provided with fibres of a selected length, the fibres extending upwardly from the upper surface and an infill layer of hollow polymer granules or an e-layer comprising said hollow granules.
