The helmet is mainly composed of an outer shell, a buffer layer, an inner lining layer and other parts. Among them, the buffer layer mainly plays a buffer effect when it encounters strong external impact, avoiding direct impact on the head and playing a protective role. The ideal buffer layer material has a certain degree of hardness (elasticity), and at the same time, from the perspective of economy and comfort, it should also meet the conditions of light weight, low cost, mature manufacturing technology, and easy ventilation.
EPS is the most commonly used helmet cushioning material in the world. It is light in weight and has low requirements for use temperature and objective conditions. It can effectively reduce the one-time impact on the wearer’s head due to energy transfer caused by impact.
