A belt comprising a foamed layer ( 1, 3, 6, 17, 23 ), characterised in that this foamed layer ( 1, 3, 6, 17, 23 ) contains a foam of a thermoplastic elastomer which in the unfoamed state has a Shore A hardness of at the most 85. The thermoplastic elastomer may in particular be a substantially random ethylene/C 3-12 -α-olefin copolymer, optionally blended with a compatible thermoplastic; a thermoplastic elastomeric block copolymer such as TPE-U; a blend of thermoplastics and elastomers; an alloy of thermoplastics and elastomers; a thermoplastic elastomeric ionomer; a blend of TPE-U with another thermoplastic elastomer; or a blend of TPE-U with an elastomer. The belt may in particular be a conveyor belt, a transport belt, a treadmill belt or a printing blanket. |
