Comparison of conductive EVA foam and anti-static EVA foam

What is anti-static (ESD) EVA foam?

Anti-static EVA  foam is a specially designed foam material that can dissipate electrostatic discharge and prevent static electricity buildup. It is widely used in industries that require anti-static solutions such as electronics, cleanrooms, and aerospace, also it is called ESD EVA (Electrostatic Discharge Ethylene Vinyl Acetate) foam.

What is the process for ESD EVA foam and Conductive EVA foam?

Conductive EVA foam and antistatic EVA foam(ESD EVA foam) are made by extruding polyethylene or modified polyethylene, conductive fillers and antistatic agents, through radiation crosslinking, and high temperature foaming to make conductive/antistatic foams. Its surface resistance And volume resistance is 103-9, permanent conductive/anti-static, smooth surface, environmentally friendly, easy to secondary molding processing, widely used in ESD related fields.

What is the features of EVA foam? 

1. Permanent conductive/anti-static function(ESD EVA foam).

2. The function of conductive EVA foam/anti-static EVA foam is not affected by environmental humidity

3. Volume resistance and surface resistance value 103—109 Ω;

4. Conductive EVA foam/anti-static eva foam is easy to re-mold and process.

Resistance of anti-static EVA foam 106-1011; resistance of conductive EVA foam 103-106

Due to the difference in resistance value, the static half-life of conductive EVA foam is much shorter than that of anti-static EVA foam, and the static voltage of conductive sponge is also much smaller than that of anti-static static. Voltage; but both can actively release charge, conductive EVA foam is more suitable for electronic products with high electrostatic sensitivity.

Conclusion:

Anti-static EVA  foamESD EVA foam is a highly effective solution for preventing the buildup of static electricity and protecting sensitive equipment. Its unique properties ensure that it is widely used in electronics, cleanrooms, and aerospace. If your business requires anti-static foam solutions, consider ESD EVA foam for the best results.
