Sports layering system

Apart from new materials, the use of established products like spacer materials and membranes will be further optimised and adapted to the specific applications. Surface treatments of fabrics to lower their infrared emissivity, and layering systems with multiple membranes, will be used more frequently in the future, as adepts of outdoor sports are constantly seeking new garments perfectly adapted to their individual needs.

Rubber crumb can be used very successfully in the manufacture of sports surfaces such as running tracks in sports stadiums and artificial turf for a variety of uses. Commercial examples of such products include a track marketed by Conica, a division of BASF, as Conipur SW, which is a sandwich system comprising an elasticated layer of recycled rubber granules and a PU binder that is applied in situ to an asphalt substrate with built-in finishers [76].
