The impact energy on the wearer’s head also depends on the thickness of the EPS buffer layer. Compared with a buffer layer with a thickness of 1 cm, when the thickness of the EPS reaches 3 cm, it will further extend the energy transmission time and make the buffer layer withstand greater impact; and when the EPS buffer layer has a lower density and a thicker layer, If the impact force is not strong, it will extend the energy transmission time instead of reaching the bottom of the buffer layer faster, making the wearer more comfortable.
Of course, if the buffer layer is too thick, on the one hand it will affect the appearance, on the other hand, it may also cause other damage in the impact. Therefore, the ideal thickness of the EPS buffer layer must ensure that it is strong enough to adapt to different types of impacts: it has a certain degree of hardness and minimizes the energy conduction on the premise of avoiding damage; and it has a certain degree of elasticity. Plays the role of absorbing collision energy in small impact.
