At NEDC, we work with a wide range of specialty materials for shielding, sealing, gasketing, and thermal management. One material we frequently convert for aerospace, defense, electronics, and RF-sensitive applications is BISCO® EC-2130, a soft, electrically conductive solid silicone developed by Rogers Corporation.
This unique material combines environmental sealing, mechanical softness, and electrical conductivity, making it a standout option for EMI/RFI shielding applications where conformability matters.
What Is BISCO® EC-2130?
BISCO® EC-2130 is a nickel-graphite filled silicone designed to provide both electrical conductivity and environmental protection around sensitive electronic assemblies.
It is engineered to be extremely soft, allowing it to seal uneven surfaces while establishing a reliable conductive path for grounding and shielding.
Key Features & Benefits
1. Extremely Soft Solid Silicone
Most conductive elastomers are firm, but EC-2130 is intentionally formulated to be very soft, allowing it to compress easily and form tight seals without high closure forces.
-
Hardness Durometer: 30 ± 5 Shore A
-
Also measured at 80 ± 10 Shore OO
Its softness makes it ideal for delicate housings and assemblies requiring gentle compression.
2. High EMI/RFI Shielding Effectiveness
EC-2130 delivers strong shielding performance across multiple frequencies, making it suitable for demanding RF environments.
Typical shielding effectiveness:
-
110 dB at 100 MHz
-
120 dB at 600 MHz
-
130 dB at 1 GHz
-
130 dB at 10 MHz
This performance level makes it a strong candidate for aerospace, microwave electronics, communication systems, and mission-critical enclosures.
3. Wide Operating Temperature Range
Silicone’s inherent stability allows EC-2130 to perform reliably in extreme conditions.
-
Operating range: –62°C to +200°C
From cold-soak applications to high-temperature electronics, the material maintains flexibility and electrical conductivity.
4. Environmental Sealing Capability
Because EC-2130 is soft, and solid (not foam), it forms effective barriers against:
-
Moisture
-
Dust
-
Particulate intrusion
-
Environmental exposure
Compression set remains low (10% max), offering long-term sealing integrity even after extended compression. Ths works for different IP rating applications.
5. Nickel-Graphite Conductive Filler System
EC-2130’s nickel-graphite filler system provides:
-
Low volume resistivity (< 1 ohm-cm)
-
Stable electrical grounding paths
-
Consistent EMI/RFI protection
This makes it useful where both electrical and environmental performance must coexist.
6. Thermal Conductivity
With a thermal conductivity of 3.33 W/m·K, EC-2130 offers notable heat-transfer capabilities, useful for assemblies that generate heat while also requiring shielding and sealing. When customers talk about a gasketing material, that is both thermally, and electrically conductive, EC-2130 is a good solution.
