Another remarkable feature of HNBR is its low compression set, which means that it resists permanent deformation when subjected to compressive loads. This is essential for timing belts, as they need to maintain their shape and tension over time to ensure proper functioning of the engine's timing system. With lower compression set values, HNBR timing belts can maintain their performance characteristics longer than those made from conventional materials.
