Hard hat is one of the necessary labor protection products in many industries, used to protect the safety of the head. Most of the helmets on the market are made of FRP, ABS and PE, among which FRP and ABS are the most popular. Therefore, when choosing helmets, people choose to use fiberglass reinforced plastic helmets or ABS helmets.
In fact, if you want to know which material is the best helmet, you need to know what are the characteristics of these two materials.Construction helmet
FRP, also known as FRP, is a fiber-reinforced composite plastic. Depending on the composite material used, it can also be divided into glass fiber-reinforced composite plastic (GFRP), carbon fiber-reinforced composite plastic (CFRP), and boron fiber-reinforced composite plastic. Wait. The helmet made of fiberglass not only has high strength, but also has excellent heat resistance and electrical insulation. It also has excellent acid resistance, water resistance and flame retardancy. It will not be easily deformed when it is under pressure.
ABS is a collection of three materials, acrylonitrile (A), butadiene (B), and styrene (S). It is a material that is classified as one of the five major plastics. A helmet made of ABS material not only has heat resistance, high surface hardness, stable dimensions, good chemical resistance, but also good electrical insulation. Changes in temperature and humidity will basically not affect the helmet, and water, inorganic salts, Substances such as alkalis and acids basically do not react.
In fact, if you want to know whether to choose a FRP helmet or an ABS helmet, it is mainly necessary to clearly distinguish the application environment of the helmet.
Because ABS helmets are not resistant to combustion and low temperature, but they have good toughness and impact resistance, they are basically unable to be used in some low-temperature or combustion-hazardous operating environments. They are only suitable for mining and machinery industries with high impact strength and normal temperature Used in the operating environment. On the contrary, FRP helmets are more suitable for use in some special operations, such as high-temperature metallurgical operations, oil field drilling, and construction in cold areas.
In fact, whether you choose a hard hat or other labor protection products, in addition to the quality of the product, you need to look at whether the product is suitable for the environment you want to use. Therefore, before labor protection products, understand the dangers in the application environment.
