In order to prevent accidents occur during work staff, the wearing of helmets can prevent or reduce the hazard to life on people's heads, but now there are many helmets material, what good does that helmet material? Today, I will introduce you to the helmets of 4 materials for your reference.
What kind of material is good for the helmet :
1. High density polyethylene material
This material has high surface hardness and good heat resistance, electrical insulation and dimensional stability, and is widely used in the production of helmets.
2. Acrylonitrile-butadiene-styrene resin
The engineering plastic has heat resistance, high surface hardness, dimensional stability and good chemical resistance. At the same time, the electrical insulation performance is good, rarely affected by temperature and humidity, and remains constant over a wide range of frequency variations. In addition, its chemical properties are also very good, with little effect on water, inorganic salts, alkalis and acids. And the impact strength is good, and it will not drop rapidly at low temperatures.
3. Glass fiber reinforced plastic
Glass fiber reinforced plastic is referred to as FRP. This material has high fiber strength, excellent heat resistance and electrical insulation properties, and has excellent acid and water resistance, flame retardancy and small deformation. It has helmets of this kind in all countries of the world.
4. Polycarbonate material
This material is hard and tough, has high impact resistance, high dimensional stability, good electrical insulation and high temperature resistance. And because some of the special materials in polycarbonate materials have good temperature resistance, many metal smelting industries require such high temperature polycarbonate material helmets.
What kind of material is the helmet ? Each material's helmet has its own advantages, and most applications have different scopes. It is recommended that you choose the helmet that suits you according to your environment.
