Power transmission belt with dual modulus behavior during operation

The invention relates to a power transmission belt (P) comprising one or more reinforcing elements (R) embedded in a polymer composition (20). The conveyor belt satisfies:-the ratio MP2/MP1 of the maximum tangential modulus MP2 produced by the conveyor belt (P) in the range of 1% to 10% elongation to the tangential modulus MP1 produced by the conveyor belt (P) at 1% elongation is greater than or equal to 2.00; and-a force generated by the conveyor belt (P) at 2% elongation is less than or equal to 120.0 daN/cm over the width of the conveyor belt (P). The conveyor belt (P) is produced using a method comprising the following steps: a step of immersing one or more reinforcing elements (R) in a polymer composition (20), followed by a curing step for forming the conveyor belt (P), wherein the reinforcing element (R) satisfies:-the ratio MR2/MR1 of the maximum tangential modulus MR2 produced by the reinforcing element (R) in the range of 1% to 10% elongation to the tangential modulus MR1 produced by the reinforcing
