EVA foam

How is EVA foam foamed?

Foaming process: At the decomposition temperature of the foaming agent, a large amount of gas is released to form a foam core. After the pressure is suddenly relieved, the foam core releases pressure to cause EVA and other materials to expand to form a foamed material.


Features of EVA foam:

Water resistance, closed cell structure, no water absorption, moisture resistance, good water resistance.

Corrosion resistance, resistance to sea water, grease, calculation, alkali and other chemical corrosion, antibacterial, non-toxic, odorless, non-polluting.

Processability, easy to process such as hot pressing, cutting, gluing and laminating.

Anti-vibration, high resilience and tension resistance, strong toughness, and has good shock-proof and cushioning properties.

Excellent heat preservation, heat insulation, heat preservation and cold protection and low temperature performance, and can withstand severe cold and exposure.

The sound insulation is strong, the cells are closed, and the sound insulation effect is good.


Advantages of EVA foam:

EVA rubber and plastic products are new environmentally friendly plastic foam materials, which have good cushioning, shock resistance, heat insulation, moisture resistance, chemical resistance, etc., and are non-toxic and non-absorbent. EVA rubber and plastic products are designed to be processed and formed, and their shock resistance performance It is superior to traditional foam materials such as polystyrene and meets environmental protection requirements, making it the best choice for export products. Compared with shock-proof packaging, it can be cut and formed. Because of its large difference in density, it can also have a wider range of uses.
