What is Conductive Foam
GALLOP INNOTEK conductive foam is a composite material composed of traditional foam and conductive coating. It is used in electronic components to protect electronic devices from electromagnetic interference (EMI) and electrostatic discharge (ESD), and to improve the electromagnetic compatibility (EMC).
The Benefits of Conductive Foam
Electromagnetic Shielding: The biggest advantage and most important function of GALLOP INNOTEK conductive foam is the electromagnetic shielding effect. Conductive foam will prevent external electromagnetic interference (EMI) from getting into electronic devices. At the same time, conductive foam can inhibit internal signal leakage.
In general, the shielding effectiveness of conductive foam is about 30~120dB and can ensure your electronic devices meet EMC standards, which is very suitable for high-frequency band applications.
Grounding and Conductivity: GALLOP INNOTEK conductive foam can form a good contact with conductive coatings and direct the static electricity to the ground wire. Thus, remove the accumulated static electricity and provide protection against electrostatic discharge (ESD).
High Elasticity: GALLOP INNOTEK conductive foam can be compressed to 30% – 50% of its original thickness. The most important thing is that the conductive foam still has stable contact after compression.
Strong Weather Resistance: GALLOP INNOTEK conductive foam has strong weather resistance. It can withstand temperatures ranging from -50℃ to 120℃. This means whether your electronic devices are used in high temperatures or cold weather, conductive foam can help them work stably.
Various Sizes: GALLOP INNOTEK conductive foam can be designed to different sizes and thicknesses (0.5-5mm) to meet your specific needs. The conductive foam can maintain stable performance in complex structural designs.
Flame Retardant: The flame-retardant grade of GALLOP INNOTEK conductive foam is V-0 grade or HB grade in the UL94 system. This means conductive foam can prevent fire and other accidents from happening.
Environmental Friendly: GALLOP INNOTEK conductive foams meet the environmental protection standards of RoHS, REACH. Through recyclable foam, non-conductive coatings, and energy-saving processes, we can meet your environmental needs.

How Conductive Foam Works?
We already know GALLOP INNOTEK conductive foam has two departments: conductive coating and inside foam. Each part has its own working process.
The conductive coating can reflect and absorb electromagnetic waves to achieve electromagnetic shielding. When electromagnetic waves interact with conductive foam, part of the electromagnetic waves are reflected back, and the rest are absorbed by the internal conductive network. The absorbed electromagnetic waves can be converted into heat energy, reducing the impact of EMI.
On the other hand, the inside foam is flexible, sealing the shielded electronic devices from external damage.
Types of Conductive Foam
Different types of GALLOP INNOTEK conductive foams actually are different combinations of conductive coatings and basic foam. There are three most common types.
Carbon-based Conductive Foam
GALLOP INNOTEK carbon-based conductive foam usually uses graphene as the conductive coating. Graphene is a porous structure with good conductivity.
The most important point is that graphene has a lightweight and good flexibility, making it suitable for fitting uneven surfaces of electronic components. If your electronic device requires lightweight conductive foam, carbon-based conductive foam is a suitable choice.
Nickel/Copper Conductive Foam
As metals, nickel and copper have good conductivity. They can also be corrosion-resistant and continue to function in any harsh environment.
Additionally, nickel-copper conductive foam is highly durable and can reduce the risks of short circuits in electronic devices.
Hybrid Conductive Foam
GALLOP INNOTEK hybrid conductive foam is a type of GALLOP INNOTEK conductive foam combining carbon-based materials and metal materials. Which means it has both the advantages of being lightweight and high conductivity.
Hybrid conductive foam can offer a better EMI shielding effect, making it applicable to a wider range of fields, such as defense equipment and communication system equipment.
The Applications of Conductive Foam
GALLOP INNOTEK conductive foams can be used in many industries.
Consumer Electronics
The production of smartphones, TVs, and computers all requires conductive foams from GALLOP INNOTEK. Conductive foams can achieve the electromagnetic shielding and grounding connections between the motherboard and case.
New Energy Vehicles
GALLOP INNOTEK conductive foam exhibits electromagnetic compatibility, making it highly suitable for high-density electronic systems. Conductive foams can effectively prevent high-voltage current from disturbing the control circuit.
You can use conductive foam in the battery management system, vehicle communication module, and other electric vehicle parts.
5G Communications
GALLOP INNOTEK conductive foams can ensure a stable 5G signal. So conductive foams are also widely used in the 5G communications field. Such as base station antennas, RF modules, and filters.
Medical Electronic Equipment
Many medical electronic equipment have strict control requirements about electromagnetic interference. GALLOP INNOTEK conductive foams can be used in medical imagers, monitors, and other precision medical instruments to protect them from EMI.
High density conductive foam has better rebound and is more stable. High density conductive foam is widely used in integrated circuits. While low density conductive foam has bad rebound and is suitable for electronic devices packing with shockproof and anti-static requirements.
Polyurethane(PU) itself is a non-conductive organic polymer material. It can have conductivity when adding a conductive coating like metal or carbon.
