Because the EVA foam material contains a large amount of air or other gases, it is not suitable for circulation. Especially the closed-cell foam material has completely separated independent cells. The material can significantly slow the conduction of heat and has a very low thermal conductivity. It also combines the softness of the material itself with good resilience.
EVA foam processing can be used as an ideal thermal insulation material for automobiles, ships, home appliances, electronic equipment, medical equipment, fitness equipment, air conditioning pipes and so on. For closed-cell foam materials, the cells separated from each other, combined with the hydrophobic properties of the selected rubber or plastic material, the foam material can prevent the penetration of water vapor and can become an ideal sealing EVA material. Rubber itself is known for its high elasticity. After the rubber is processed into a foam material, it still maintains a very high resilience, which is very suitable for cushioning high elastic shock.
The open cells in the open-cell foam material communicate with each other and communicate with the outer skin, and are non-independent cell structures, mainly larger cells or coarse cells. Therefore, according to the actual needs of customers, EVA materials should be selected according to the actual needs of customers to make products that meet customer needs and improve customer satisfaction.
