Helmets are generally composed of an outer shell, cushioning layer, inner lining, straps, lenses, etc. Among them, the outer shell is the outermost layer of the helmet, which can withstand and disperse impacts during impact, and is the first line of defense to protect the head. Therefore, the choice of helmet shell material is crucial. The commonly used shell materials include ABS, polycarbonate (PC), carbon fiber, etc.

So, what material is used for the shell of the YEMA helmet? Most helmet shells on the market are made of ABS material, and most of YEMA’s helmets are the same. But besides ABS, YEMA also has several helmets made of carbon fiber material. Next, let’s talk in detail about the characteristics of these helmet shell materials.

ABS (acrylonitrile butadiene styrene copolymer):
ABS is a common material for helmet shells, which has good impact resistance and can absorb and disperse impact forces in accidents, protecting the head from injury. Helmets made of ABS material are usually more economical. The most common helmet on the market currently is made of ABS material, which is lightweight, strong, sturdy and resistant to falls, and has good comprehensive protective performance. YEMA helmets made of ABS material not only have high safety, but also are affordable in price. Many people choose YEMA helmets when buying helmets.

Polycarbonate (PC):
Polycarbonate is an amorphous, odorless, non-toxic, highly transparent colorless or slightly yellow thermoplastic engineering plastic that has excellent impact resistance and can provide higher levels of protection in accidents. Polycarbonate helmets are usually lightweight and offer high durability.

Carbon fiber:
Carbon fiber is a very lightweight but extremely strong material commonly used in high-performance and racing helmets. Carbon fiber helmets have excellent impact resistance and lightweight characteristics, providing a higher level of protection. Of course, carbon fiber helmets are usually expensive. The helmet shells of YEMA 628S, 636S, 836S, and 930S are also made of carbon fiber material, with relatively high prices, including three quarter helmets, half helmets, open face helmets, and full helmets.

Fiberglass: The fiberglass shell has high impact resistance and is lighter than ABS. It is commonly used in high-performance fields such as ski helmets and motorcycle helmets.

Composite materials: Some high-end helmets use a composite shell, usually a mixture of polycarbonate, carbon fiber, glass fiber, etc. These materials combine lightweight and excellent protective performance, but are relatively more expensive.

Different types of helmets may use different shell materials, depending on the design of the helmet, expected usage scenarios, and price point. Regardless of the material of the shell, it is necessary to ensure that the helmet meets national safety standards and passes the national 3C certification to provide sufficient protection.
