one Helmet AB resin material is a common engineering plastic with high cost performance, strong impact resistance and good dimensional stability.

Market price of material helmets: usually 100 to 300 for full helmets

The strength and toughness of PC+ABS alloy are superior to ABS. Both strength and toughness have been greatly improved. Low temperature impact performance is also very high. The price is between 300-1000 yuan. The current market is relatively broad

FRP helmet is made of fiber reinforced plastic, which is light in weight and strong in strength, but it is difficult to make and has low batch production capacity

Carbon fiber has a high technical content, characterized by light weight and high strength, but its price is relatively expensive, generally more than 1000 yuan

PP materials are usually toys or decorative helmets with poor safety. Of course, wearing a helmet is cheaper than wearing a PP helmet.

The safety factor from high to low is: carbon fiber>FRP>PC+ABS alloy>ABS resin

2 Helmets

Helmets can be divided into full helmet, 3/4 helmet, half helmet and top hat. The type of helmet is directly related to the riding comfort.

three . Helmet

The head protection is good, but it will be muggy when combined, suitable for winter travel. It is recommended to use helmets on the vehicle every day.
