EPDM-ribbed belt

In recent years, the engine room temperature getting higher and higher, some pieces of rubber capability requirements 150 ��, and instantly the capability 170 ��, the traditional chloroprene rubber (CR) is. As HNBR too expensive, people in the study found that a small amount of oil is not on the front of the belt, causing engine damage can use the cheaper good heat resistance EPDM rubber (EPDM), as the main rubber-ribbed belt material. But EPDM wear resistance, high temperature slitting-resistant and dynamic performance is not satisfactory, poor adhesion with other materials, which are modified as needed or add ZDA ZDMA and with other materials and used to solve the problem.
EPDM-ribbed belt high temperature performance and high temperature fatigue life markedly improved, such as CR 107 �� ribbed belt under fatigue life of only 50 h, and EPDM 121 ribbed belt in the fatigue life of up to 125 h. EPDM development of the mainland reached 240,000 Km-ribbed belt life.
