Low permeability is good light helmet risk;
Ventilated good, lightweight, comfort for the wearer to provide comprehensive;
Protection of safety helmet
When workers head hit by falling objects, using the helmet shell cap, cap line first in a flash will impact on the whole area of decomposition to the skull, then USES the elastic deformation of each part of the helmet buffer structure, plastic deformation, and allow the structure of the damage to most of the shock absorption, reduce the impact of the final effect to the head to under 4900 n, so to protect the workers in the head.Safety helmet hat shell material on the helmet overall combat performance plays an important role.
