Excellent UV resistance, long-term exposure to construction sites, outdoor sunlight, and alternating high and low temperature environments, making it less prone to cracking, brittleness, and deformation. Its service life is more stable than ordinary ABS materials. Wide temperature resistance range, can be used stably at -30°C ~ 50°C, and can maintain toughness even in low temperature environments. It will not become brittle when exposed to cold like some materials, and is suitable for working in various climatic regions such as temperate and cold zones.

It has strong tolerance to water, inorganic salts, acid-base solutions, and most organic solvents, and can resist chemical splash erosion in chemical, petroleum, sewage treatment, and other scenarios. Its protective range is wider than ordinary materials. The surface is smooth and dense, not easily penetrated by oil stains and corrosive liquids, and cleaning and maintenance are more convenient, reducing the wear and tear of safety helmets caused by environmental factors.

HDPE has a low density, and under the same protection standards, it is lighter than ABS material. Wearing it for a long time will not cause additional burden on the neck, especially suitable for scenarios such as logistics and forestry that require all day work, which can effectively reduce fatigue.

The molecular structure is non-polar and has high insulation resistance, which can meet the basic insulation protection requirements of power operations. It is suitable for scenarios such as substations, line construction, and power maintenance, and expands the usage boundaries of safety helmets.

High crystallinity, tightly arranged molecular chains, good toughness and flexibility, capable of buffering impact force through self deformation when subjected to impact, avoiding brittle fracture, and can stably pass impact and puncture tests according to mainstream safety standards. By combining reinforced ribs, thickened brim and other structural designs, the anti lateral pressure performance can be further optimized to meet the protection needs of most common work scenarios.

The raw material cost is lower than that of engineering plastics such as ABS and PC, and the injection molding process is mature, suitable for large-scale production. It is one of the preferred materials for universal safety helmets.
