Conductive Foam | Anti Static Foam Tape
What is Conductive Foam?
Conductive foam has lower electrical resistance than anti-static foam, making it easier and faster for electrons to flow across the material.
There are two types of conductive foam:
1. Black Anti-Static and Conductive Foams (Polyethylene Foam)
Black conductive foams are made of polyethylene material with added conductive agents. They have eco-friendly, cushioning, and waterproof features. They are mainly used for protecting static-sensitive components and electronic assemblies.
It is a closed-cell rigid foam, meaning no foam scraps are lost, and it has no smell. It can be repeatedly used with permanent anti-static/conductive features.
It contains internal anti-static agents that eliminate static potential from the foam itself and dissipate electrostatic discharges from other sources.
2. Conductive Foam (Polyurethane Foam)
Conductive polyurethane foam is made of polyurethane foam, which is open-cell soft foam with good shockproof, sound absorption, and heat insulation properties. This foam can be used for fine packaging of electronic components or special safety inspection purposes.

Conductive / ESD foam packaging
As different electronic components shape or requests, we make the conductive / ESD foam packaging material by cutting, gluing, heating lamination, pouching ways, such as the foam tray, foam insert , foam box, and foam container etc. Below are some of conductive / ESD foam packaging material for your reference.
-
Conductive / ESD foam tape / gasket
For some small electronic products, for example, phone, tablet PC, and other electronic products, conductive foam tape / gasket takes small space , with the functions for sealing, cushioning, moisture proof , anti static or conductive. It is widely used in current electronic factory.
Conductive / ESD Foam Applications:
- Electronic components packaging: such as PCB or IC chips storage, pressure Sensors and electrical connectors , static sensitive parts.
- Electronic display: LED or LCD Screen, Graph display.
- Static sensitive equipment: such as Medical devices , Portable data acquisition & ruggedized devices, and other shield devices.
- Tiny electronics sealing : such as phone, Tablet PC.
Conductive / ESD Foam Price
The price of conductive / ESD foam varies depending on the type of foam. For example, polyethylene foam is eco-friendly and has permanent anti-static and conductive properties, which makes its price higher than that of polyurethane foam. It's worth noting that while polyurethane foam is softer than polyethylene foam, customers can choose the right product based on their specific electronic component packaging needs.
