Abstract: A thermoplastic polyurethane foamed article has a density ranging from 0.3 to 0.8 g/cm3 measured at 25° C. and is self sealable in accordance with Section 7.9 of ASTM D1970/D1970M-11. The thermoplastic polyurethane foamed article is formed by melting and foaming a thermoplastic polyurethane composition having a durometer hardness ranging from 30A to 75D in the presence of a blowing agent.

Abstract: An artificial turf contains a damping layer made of a particle foam, a fiber backing, and an artificial grass layer made of single or multiple fibers. The fibers are tied to the fiber backing, forming an artificial carpet of grass. The particle foam and the single or multiple fibers forming the artificial grass layer are each made of a thermoplastic elastomer.
