The invention relates to conveyor belts, which have a laminate consisting of: i) a textile ply ( 1 ) with a first ply surface ( 11 ) and with a second ply surface ( 12 ); ii) a first synthetic material ply ( 2 ), which adheres to the first ply surface ( 11 ), is made of a thermoplastic material having a creep resistance v<SUB>k </SUB>of no greater than 0.005 at 30° C., and which contains at least 70% by weight of a thermoplastic having a creep resistance v<SUB>k </SUB>of no greater than 0.005 at 30° C.; and iii) a second synthetic material ply ( 3 ), which adheres to the second ply surface (12), is made of a thermoplastic material having a creep resistance v<SUB>k </SUB>of no greater than 0.005 at 30° C., and which contains at least 70% by weight of a thermoplastic having a creep resistance v<SUB>k </SUB>of no greater than 0.005 at 30° C., with the provision that the quotient r<SUB>v </SUB>of formula (I): <maths id="MATH-US-00001" num="00001"> <MATH OVERFLOW="SCROLL"> <MROW> <MROW> <MSUB> <MI>r</MI> <MI>v</MI> </MSUB> <MO>=</MO> <MROW> <MFRAC> <MROW> <MSUB> <MI>V</MI> <MI>B</MI> </MSUB> <MO></MO> <MSUB> <MI>rho</MI> <MI>T</MI> </MSUB> </MROW> <MSUB> <MI>G</MI> <MI>T</MI> </MSUB> </MFRAC> <MO>-</MO> <MN>1</MN> </MROW> </MROW> <MO>,</MO> </MROW> </MATH> </MATHS> wherein V<SUB>B </SUB>represents the surface volume of the laminate, rho<SUB>T </SUB>represents the density, and G<SUB>T </SUB>represents the weight per unit area of the textile ply ( 1 ), results in a value ranging from 5 to 25. These conveyor belts can be joined to form endless conveyor belts via butt end connections.
