ABS material has a certain degree of puncture resistance, and the national standard ABS V-shaped safety helmet is designed to withstand a certain degree of sharp object puncture. The ABS engineering plastic used in the cap shell has high strength. When sharp objects come into contact with the cap shell, the material of the cap shell can prevent sharp objects from penetrating through it through its own toughness and strength. But if the impact force of a sharp object is too strong or too sharp, exceeding the protection limit of the safety helmet, puncture may still occur. However, compared to ordinary materials, ABS helmets have significant advantages in puncture resistance, providing better protection for the head and reducing the possibility of injury caused by sharp object punctures.
