👉 Helmet fluid, also known as impact absorption fluid or energy management fluid, is a specialized material designed to enhance the safety and performance of helmets, particularly in high-impact scenarios like motorcycle or bicycle accidents. This fluid is typically a viscous, shear-thinning liquid that flows easily when subjected to sudden impacts, such as those experienced in collisions. Upon impact, the fluid rapidly thickens and absorbs a significant amount of energy, distributing it over a larger area and reducing the force transmitted to the wearer's head. This mechanism not only helps in minimizing the risk of head injuries but also contributes to overall comfort and durability by reducing vibrations and shocks felt by the rider.
