Silver-Copper Fluorosilicone EMI Shielding Elastomer

SSP2573-75 (Type C)

SSP2573-75 is a 75-durometer, silver-plated copper filled fluorosilicone elastomer engineered to meet MIL-DTL-83528 Type C requirements. It combines strong EMI/RFI shielding performance with the chemical and fuel resistance demanded in aerospace, defense, and harsh-environment industrial applications.

Material Overview

  • Base Polymer: Fluorosilicone (75 Shore A)
  • Conductive Filler: Silver-plated copper
  • Specification: Meets MIL-DTL-83528 Type C (QPL listed)
  • Shielding Effectiveness: Typical >110 dB shielding over 20 MHz–10 GHz when properly installed
  • Temperature Range: –55°C to +160°C (per MIL-DTL-83528 Type C)
  • Chemical Resistance: Excellent resistance to fuels, oils, hydraulic fluids, solvents, and jet fuel due to fluorosilicone base
  • Form Availability: Supplied as cured sheet material or compound; ideal for die-cutting, waterjet, and precision converting

Key Features

  • Fluorosilicone Base for Harsh Environments – Provides superior resistance to fuels, oils, solvents, and aggressive fluids compared to standard silicone.
  • High-Conductivity Silver-Copper Filler – Delivers excellent EMI/RFI attenuation when properly compressed against conductive mating surfaces.
  • MIL-Spec Type C Qualification – Ensures controlled electrical, mechanical, and environmental performance for military and aerospace applications.
  • 75 Durometer Hardness – Supports applications requiring higher sealing force, structural stability, and precise compression retention.
  • Dimensional Stability for Complex Gasket Designs – Converts cleanly into intricate geometries and thin-wall profiles via SRP’s cutting technologies.

Applications

  • Aerospace electronics exposed to fuels or hydraulic fluids
  • Avionics enclosures, missile systems, radar equipment
  • Military vehicles and tactical communication systems
  • Chemical-processing instrumentation and industrial machinery
  • Connector gaskets, door and panel seals, and access-cover gaskets
  • Any EMI shielding interface where standard silicone would degrade due to fluid exposure
