BELT WITH BIMODULUS BEHAVIOR DURING OPERATION

A power transmission belt (P) comprises one or more reinforcing elements (R) embedded in a polymeric composition (20). For the belt, a ratio of the maximum tangent modulus MP2 in the range from 1 to 10% elongation to the tangent modulus at 1% elongation MP1 MP2/MP1 is greater than or equal to 2.00....

Beschreibung
Zusammenfassung:	A power transmission belt (P) comprises one or more reinforcing elements (R) embedded in a polymeric composition (20). For the belt, a ratio of the maximum tangent modulus MP2 in the range from 1 to 10% elongation to the tangent modulus at 1% elongation MP1 MP2/MP1 is greater than or equal to 2.00. The force at 2% elongation over the width of the belt (P) is less than or equal to 120.0 daN/cm. The belt (P) is obtained by embedding one or more reinforcing elements (R) in a polymeric composition (20). For the reinforcing element, a ratio of the maximum tangent modulus MR2 in the range from 1 to 10% elongation to the tangent modulus at 1% elongation MR1 MR2/MR1 is greater than or equal to 2.00. The force at 2% elongation over the diameter of the reinforcing element is strictly less than 11.0 daN/mm.
