What kind of material should be used for the cushion pad?

According to the specific needs, the cushion can be made of foam, shock absorption adhesive, EVA, etc. Each material has its advantages and disadvantages. When selecting, you need to consider the use scenario and use needs.

1、 Foam material

Foam material is a common cushion material, which is mainly made of polyethylene. This material is commonly used in industrial and sports fields, such as packaging, protection, and shock absorption. The foam material has the characteristics of light weight, durability, softness and shock absorption, which can provide better cushioning effect.

However, foam material also has its disadvantages. For example, it has strong water absorption and is not suitable for humid or water immersed environments. At the same time, the processing of foam materials is difficult and requires professional processing equipment and technology.

2、 Shock-absorbing adhesive

Shock absorber adhesive is a high molecular polymer material commonly used for sole cushioning in sports shoes, which can provide excellent cushioning and shock absorption effects.

The characteristics of shock-absorbing adhesive are softness, wear resistance, durability, and resistance to deformation. At the same time, shock absorbers can be designed according to needs, with various shapes, making them more flexible and suitable for various fields.

However, shock absorbers also have their drawbacks. Due to the softness of the material, it is not suitable for environments that require higher hardness. In addition, the processing cost of shock absorber adhesive is relatively high, requiring special processing techniques and equipment.

3、 EVA material

EVA material is a polyethylene material widely used in the manufacturing process of sports shoes, outdoor shoes, backpacks, etc. It has good cushioning, flexibility, and durability.

EVA material is soft and durable, with good elasticity and a long service life. Moreover, it has less difficulty in molding and is easier to process into the desired shape.

However, EVA material has high water absorption and is not suitable for water immersion environments. Meanwhile, due to the soft material, different densities and hardness need to be selected for different fields.

4、 Summary

In summary, the selection of cushion materials needs to be comprehensively considered based on specific application environments and requirements. Foam material, shock absorption adhesive and EVA material are common materials, and the best effect can be achieved by selecting different materials according to different fields and application requirements.
