The EPS foamed polystyrene foam material is used because it is a high-impact material and has an anti-vibration buffering effect. Its low density and light weight are also one of the reasons why this material is used in safety helmets.
There is another lining material, EPP foamed polypropylene, which also has a very good impact buffering effect, but EPP's impact resistance is far less than EPS when it absorbs impact.
The use of polymer foams is mainly because they are easy to shape and their ability to absorb energy is also more comprehensive. The density and thickness of the helmet designers are selected empirically and designed to meet the 5m second standard impact test constant speed.
Inner lining protection material - has been evolving, in recent years a new type of multi-foam Tau ReUp has been born, which is a combination of EPS and EPU polyurethane foam, and multi-protective foam is also developing.
The outer material of bicycle riding helmets is mainly composed of carbon fiber, while some high and low helmets use titanium fiber materials.The above is the information about helmets.
