What are main materials for production of popular helmets in Moments?

Recently there has been another wave of buying helmets among friends, either buying helmets in large quantities or buying special materials for helmets. After mask and meltblown hype is over, will helmets be next new hype opportunity?

What are main materials for production of popular helmets in Moments?

Therefore, in era of survival of those best suited for melt blown masks, popularity of safety helmets has skyrocketed, and material companies, processing companies, and equipment companies have benefited. This will inevitably lead to an explosive growth in consumption due to rapid development of industry.

By way, will editor analyze for you what materials helmet is made of?

1. The main structure of helmet shell

A helmet usually includes an outer shell, buffer layer, inner lining, jaw guard, lanyard, lens, etc. where,

The shell is outermost layer of helmet that absorbs and dissipates impact during impact, so choice of shell material is very important;

Buffer layer plays a buffer role in case of a strong impact. It is usually made from non-toxic, harmless, sweat-absorbent and breathable materials that can absorb impact energy. The buffer layer is made of hair, material is expanded polystyrene (EPS).

Second, material of helmet shell

The material of helmet shell is mainly ABS or PC material, among which helmet made of ABS material is used in civilian applications, and helmet product is relatively inexpensive.

Because of their relatively good toughness and impact resistance, polycarbonate materials are mainly used for mid to high end motorcycle and racing helmets.

In addition, there are fiberglass helmets, carbon fiber helmets and nylon helmets, etc., and quality of these helmets is relatively high, so it belongs to high quality material of helmet shell.

Third, material of inner shell of helmet

The cushioning material inside helmet, commonly known as impact resistant material of helmet, is mainly composed of EPS (expanded polystyrene) or EPP (expanded polypropylene) and other materials.

EPS material is a styrene polymer material, and input is ethylene and pure benzene.

EPP material is made from modified PP material. Among them, EPS material helmet is relatively cheap and widely used, and EPP material helmet is mainly high-end helmets.

What are main materials for production of popular helmets in Moments?

Common materials for bicycle and motorcycle helmets consist of several parts:

1. PC: polycarbonate for short, strength of PC can meet needs of bulletproof glass, and its strength and toughness are very good.

2.ABS: Ternary block copolymer of styrene, acrylonitrile and butadiene. ABS has both stiffness and toughness and is a good material for a case.

This is an ordinary plastic, from which a net is usually made and wound around head at a distance of 2-3 cm from shell, so that head does not come into direct contact with shell.

Fourth, protective foam

EPS: Expandable polystyrene for short, commonly known as Styrofoam.

Expanded polystyrene foam is a type of thermoplastic material that is different from conventional foam materials. After heating and foaming, each cubic meter of Styrofoam contains 3 to 6 million independent closed air cells, and volume of air contained is more than 98%. .

The foam is placed between inner and outer shells, filling space between inner and outer shells and acting as cushioning and impact protection.

5. Carbon fiber material

This is most important part of helmet, requiring light weight, high hardness and strength. Carbon fiber is a new type of fibrous material with a carbon content of more than 95%, which has high strength, high modulus, low density, and small coefficient of linear expansion in terms of physical properties. It is a military-grade material.

In addition, materials such as masks and chin straps are also standard on professional helmets.
