Using a polyol mixture comprising PBD for creating a PU-based artificial turf

An artificial turf, comprising:

• a polyurethane backing, the polyurethane being a reaction product of first and second polyols with an isocyanate,
• the first polyol being polyether polyol and/or polyester polyol having at least 2 hydroxyl groups per molecule, the second polyol being polybutadiene diol,
• the isocyanate comprising isocyanate monomers, isocyanate polymers or isocyanate prepolymers or a mixture thereof, the isocyanate monomers, the isocyanate polymers and the isocyanate prepolymers having two or more isocyanate groups per molecule, wherein the polyurethane backing is formed from a non-foamed liquid polyurethane mass, wherein the non-foamed liquid polyurethane mass has a density in a range of 1100 g/l-1500 g/l, wherein the polybutadiene diol has an amount of 2.0-4.0% by weight of a combination of the first polyol and the isocyanate, and wherein the non-foamed liquid polyurethane mass includes a pale oil in an amount of 0.5% to 4% by weight of a combination of the first and second polyols and the isocyanate;
• a carrier;
• and
• an artificial turf fiber incorporated into the carrier such that a first portion of the artificial turf fiber protrudes to a front side of the carrier and a second portion of the artificial turf fiber is located at a back side of the carrier, the second portion of the artificial turf fiber being incorporated into the polyurethane backing, wherein
• the polyurethane backing is only on the back side of the carrier and only the second portion of the artificial turf fiber is incorporated into the polyurethane backing.
