Anti-static properties of EVA foam
- 2022-04-06 -

EVA foam on the market is widely used and has many products. It is a kind of plastic particle foam material, and the product itself does not have anti-static properties. It is an anti-static EVA foam. After adding a certain amount of conductive carbon powder, it will form a conductive network inside and realize the function of anti-static. The surface pores are small and the closed-cell structure has many excellent characteristics such as waterproof, moisture-proof and shock-proof.

EVA rubber and plastic products are a new type of environmentally friendly plastic foam material, which has the advantages of good cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc., and is non-toxic and non-absorbent. It can be used to make refrigerator ducts, gas pipes, civil construction plates, containers, and daily necessities. It can also be used to make packaging films, gaskets, and medical equipment. It can also be used as hot-melt adhesives, cable insulation, etc. At present, it is used in the solar cell industry to bond the cells in the crystalline silicon cell with the surface photovoltaic glass and the cell back sheet.

EVA foam has the functions of shockproof, waterproof, moisture-proof, static electricity, etc., but it does not have the functions of anti-static and conductive. In addition to the characteristics of ordinary foam, anti-static EVA foam also has certain anti-static properties. Its anti-static index value is between the 6th power of 10 and the 8th power of 10. The conductive foam has the same characteristics as ordinary foam, and its surface resistance is from the 3rd power of 10 to the 5th power of 10.

Anti-static EVA foam has anti-static properties. Although they all have certain anti-static properties, in actual applications, the direction of application will vary according to the resistance value of the product surface. For example, when purchasing EVA foam, some communication companies will specifically require the static electricity index to be around 10 to the 4th power, while some will emphasize that EVA foam should be used within the anti-static index.

EVA foam is a very high-quality environmentally friendly packaging material, and it is also a highly customized product. It can be customized for flame retardant, antistatic, and standardized according to the needs of customers, which greatly meets the needs of customers.
