The hardness range of hydrogenated nitrile rubber rollers is usually between 50A and 90A. Specifically, hydrogenated nitrile rubber rollers with lower hardness (such as 50A-60A) are mainly used in situations requiring higher elasticity and better adaptability, while hydrogenated nitrile rubber rollers with higher hardness (such as 80A-90A) are suitable for environments with greater pressure and high temperature.
