1. Why the Difference Matters
In the world of ESD packaging foam, choosing between anti static EVA foam and conductive EVA foam is not just a technical detail—it directly impacts the safety and reliability of your sensitive electronics.
While both foams provide cushioning and ESD protection, their surface resistance ranges determine where they perform best:
· Anti static EVA foam: 10⁵–10⁹ Ω
· Conductive EVA foam: 10³–10⁶ Ω
�� 2. Where to Use Anti Static EVA Foam
Anti static EVA foam is designed for general electronics packaging and handling, where static must be controlled but not rapidly discharged.
✅ Typical applications:
· Consumer electronics packaging
· PCBA trays and cushioning
· Returnable totes for light electronic modules
· General ESD packaging foam use
Value: Cost-effective, versatile, and suitable for most electronics without extreme ESD sensitivity.
⚙️ 3. Where to Use Conductive EVA Foam
Conductive EVA foam provides a low-resistance path to ground, making it ideal for industries where even minor static buildup can cause critical failures.
✅ Typical applications:
· Semiconductor chips and wafers
· Optical modules (transceivers, laser diodes)
· AI servers and robotics sensors
· Cleanroom and laboratory packaging
Value: Ensures absolute ESD safety, compatible with conductive cushioning material needs in high-reliability industries.

�� 5. Final Thought
If you need versatile ESD packaging foam for everyday electronics, anti static EVA foam is your go-to solution.
But if you work with semiconductors, optics, or robotics where zero tolerance for static damage is required, only conductive EVA foam can deliver the permanent, low-resistance protection you need.
At YUFA Polymer, we supply both anti static EVA foam and conductive EVA foam, customized into trays, inserts, and cushioning systems to meet your exact requirements.
