Tech Talk: Value of PA46 in elastic multi-V belts

Higher chain regularity in PA46 versus PA66 explains the root cause of faster crystallization and higher crystallinity. These factors result in superior stiffness, strength, creep and stress decay at temperatures typically occurring in automotive under-the-hood applications. During this 30-minute Talk about front end accessory drives, Jippe van Ruiten, application development manager, discusses how elastic belts save cost and weight by simplifying the belt drive system. He also explains how the low creep performance of PA46 cords in these belts enable a much lower initial belt stress that extends bearing life and improves fuel economy.
