Nickel-Coated Graphite EPDM EMI Shielding Elastomer
SSP2514-75
Non-Silicone, EPDM-Based Conductive Elastomer for EMI/RFI Gaskets with Enhanced Environmental Resistance
SSP2514-75 is a 75-durometer, nickel-coated graphite filled conductive EPDM elastomer designed for EMI/RFI shielding in applications where silicone or fluorosilicone may not be recommended. This non-silicone material combines reliable conductivity with strong resistance to ozone, UV exposure, weathering, and environmental stress, making it a practical choice for outdoor electronics, utility enclosures, telecom cabinets, and industrial control housings.

Why Engineers Choose SSP2514-75
- Non-Silicone EPDM Construction – A strong option for applications where silicone and fluorosilicone are not preferred or may be chemically incompatible.
- Weather, UV, and Ozone Resistance – EPDM provides strong durability in outdoor environments exposed to sunlight, moisture, and weather extremes.
- Reliable EMI/RFI Shielding Performance – Nickel-coated graphite filler delivers conductive performance for shielding and enclosure gasketing applications.
- Good Mechanical Properties for Durable Seals – The material offers solid tensile strength, elongation, tear resistance, and compression behavior for long-term service.
- Cost-Conscious Alternative for Outdoor EMI Gasketing – Provides conductive shielding performance without relying on precious-metal filler systems.
Applications
- Outdoor electronics, telecom cabinets, and industrial control enclosures
- Utility and infrastructure equipment exposed to sunlight, moisture, or weather extremes
- Junction boxes, housings, and access panels requiring EMI shielding plus environmental sealing
- Applications where silicone or fluorosilicone is not preferred due to environmental exposure or material-compatibility requirements
- EMI interface gaskets that also require robust environmental performance
