Inner Padding For Motorcycle Helmets

Several types of inner padding are available for motorcycle helmets. The types are Solid, Multi-impact, Dual-density, and E-PLA. Read on to find out more about each of them and the benefits they provide. It is also important to know how each layer fits into the overall structure of the helmet. EPS pads are most common, but there are also other types, including E-PLA.

Solid EPS

Foam padding is an affordable and durable padding solution that can be custom-designed and fabricated. It is versatile, lightweight, shatter proof, and wear and tear resistant. It is also useful in minimizing vibrations and noises, insulating rooms and vehicles, and expanding elastomeric tires and wheels. Because foam padding is closed-cell, it does not break down when exposed to moisture or the elements.

Multi-impact EPS

The new models of EPS and AC liners for motorcycle helmets have significantly improved the performance of AC-lined helmets. The AC lining has significantly lower thickness than EPS, allowing for direct comparison of the two types of inner padding. Further, the YEAHM model has significantly lower thickness than the standard criteria and can be applied to a wide range of helmet designs. This paper discusses some of the advantages of AC liners for motorcycle helmets and offers some useful recommendations for improvement.

Dual-density EPS

One way to make your EPS helmet better is to install cones. They create a smooth transition between the two layers of foam instead of a flat line or abrupt transition. The Alliance of Foam Packaging Recyclers provides information on this process. However, you should keep in mind that it is not always feasible to recycle your helmet's EPS. That's because it would require a lot of fossil fuel to transport the old helmet to a foam recycler.


While the EPS inner shell is the most common inner liner used in cycling helmets, there are alternatives. E-PLA, or Expanded Polylactic Acid, is a biodegradable material derived from corn that offers similar impact protection to EPS. As long as you recycle the helmet properly, E-PLA will not leave a negative impact on the environment.


HexR helmets are 3D printed to fit the individual head of each rider. The lining is made of hexagonal honeycomb cells and can be scanned in London or on the go using an iPhone. Although there are currently no models for children, they are currently available for PS300. For further information, please visit

Dual-density EPP

In a crash, the EPS will absorb the force and disperse it evenly to provide maximum cushioning. The material is composed of small beads of polystyrene about the size of a table salt. These beads are compressed with the help of pentane and expand by two to fifty times. Under ideal conditions, the beads are tightly bonded, while under adverse conditions they may show hidden recesses and break.


The most important component of a bicycle helmet is the liner. A thick, protective liner is not only important for protection, but it also looks great. The Silo model from Giro uses a biodegradable Expanded Polylactic Acid liner, which is made from corn. This type of foam is softer than standard EPS, yet has the same density. It is biodegradable and requires no special treatment and can be reused after a crash.
