Foam rubber is a kind of polymer material, it is made of rubber and plastic as the main material, through a series of processes such as foaming, so that the rubber and plastic inside the formation of a closed bubble structure, these bubbles evenly distributed in the material, giving the material light, soft characteristics.

Foamed rubber can be used for shock absorption to a certain extent, thanks to its structure. When subjected to external shock or vibration, these tiny pores can effectively absorb and disperse the impact energy, thereby reducing the impact of vibration on the material itself, so as to play a certain shock absorption effect. At the same time, the porous foam structure can also produce a certain damping effect, which further inhibits the propagation of vibration.

The damping properties of foamed rubber are also related to its density and bubble structure. By adjusting the density of the material and the bubble size, the damping effect can be further optimized. Higher densities and smaller bubble sizes generally mean better shock absorption, as such structures are able to absorb and disperse shock energy more efficiently.

In addition to being used in the field of thermal insulation, foamed rubber is also used in areas where vibration transmission needs to be reduced or equipment is protected from vibration.

For example, in the construction industry, foamed rubber is often used as insulation material, which can not only reduce the transfer of energy, but also effectively reduce the vibration and noise generated by pipelines and equipment during operation. In the field of vehicles and ships, foam rubber is also widely used in the production of shock absorbing materials, which can reduce the vibration generated by mechanical parts during operation and improve the comfort and stability of the ride.

It should be noted that the shock absorption performance of foam rubber is not universal. In some special environments, such as extreme high or low temperature conditions, the performance of the material may be affected, resulting in reduced damping effect. Therefore, when choosing foam rubber as a shock absorber material, it is necessary to make reasonable selection and design according to the specific use environment and requirements.

The closed-cell foam structure of foamed rubber plastics makes it have good shock absorption performance, which can effectively absorb and disperse shock energy, and provide effective shock absorption solutions for many fields.
