Silver-Copper Silicone EMI Shielding Elastomer
SSP2571-85 (Type K)
High-Durometer MIL-DTL-83528 Type K Silicone for Rigid EMI/RFI Gasket Structures
SSP2571-85 is an 85-durometer, silver-plated copper filled conductive silicone elastomer engineered to meet MIL-DTL-83528 Type K requirements. It offers excellent EMI/RFI shielding performance and exceptional hardness for applications that require higher sealing force, structural rigidity, and dimensional stability.
Material Overview
- Base Polymer: Silicone (85 Shore A)
- Conductive Filler: Silver-plated copper
- Specification: Meets MIL-DTL-83528 Type K (QPL listed)
- Shielding Effectiveness: Typical >110 dB shielding from 20 MHz–10 GHz when properly installed
- Temperature Range: –55°C to +160°C (per MIL-DTL-83528 Type K)
- Form Availability: Supplied as cured sheet material or compound; ideal for die-cutting, flash cutting, waterjet, and other precision converting methods
Key Features
- High-Durometer 85A Silicone – Ideal for applications requiring rigidity, defined gasket edges, and higher compression force—well-suited for large frames or flat gasket designs where stability is essential.
- Silver-Copper Conductive System – Provides excellent EMI/RFI attenuation and strong electrical continuity for mission-critical electronics.
- MIL-Spec Type K Qualification – Ensures controlled conductivity, mechanical properties, and shielding performance consistent with military EMI gasket requirements.
- Dimensional Stability Under Load – Higher hardness supports sharper cut profiles, minimal deformation, and reliable long-term compression performance.
- Conversion-Ready Sheet Format – Cuts cleanly into intricate geometries and large-format seals for enclosures, access panels, and electronic housings.
Applications
- Military and aerospace enclosures requiring rigid EMI gasket structures
- Large flat-panel gaskets, hatch seals, and precision frame gaskets
- High-force compression zones where softer elastomers would deform
- Defense communication systems, radar, and hardened electronics
- Industrial or telecom equipment demanding consistent EMI performance over long service life
