Silver-Copper Silicone EMI Shielding Elastomer

SSP2569-65 (Type A)

SSP2569-65 is a 65-durometer, silver-plated copper filled conductive silicone elastomer designed to meet MIL-DTL-83528 Type A requirements. This QPL-listed material is commonly used as a CHO-SEAL® 1215 alternative for EMI/RFI gasketing in military, aerospace, industrial electronics, and communication equipment.

Material Overview

  • Base Polymer: Silicone (65 Shore A)
  • Conductive Filler: Silver-plated copper
  • Specification: MIL-DTL-83528 Type A, QPL Listed
  • Shielding Effectiveness: ≥110 dB at 10 GHz (plane-wave shielding per MIL-DTL-83528 test methods). Typical performance across 20 MHz–10 GHz when properly installed
  • Temperature Range: Continuous use: −55°C to +125°C (per MIL-DTL-83528 Type A). Short-term excursions may vary—verify for application conditions
  • Comparable CHO-SEAL® Cross-Reference: CHO-SEAL 1215
  • Form Availability: Supplied by SSP as sheet material and formulated compound; SRP converts into finished gasket geometries (SRP does not mold or extrude materials)

Why Engineers Choose SSP2569-65

  • High EMI/RFI Shielding Performance – Silver-plated copper filler delivers strong electrical conductivity and reliable shielding for demanding electronic applications.
  • MIL-DTL-83528 Type A, QPL Listed – Designed for specification-driven programs requiring proven conductive elastomer performance.
  • Reliable Silicone Sealing – The silicone base helps maintain compression, sealing force, and electrical contact in challenging environments.
  • Trusted Alternative to CHO-SEAL® 1215 – A common cross-reference for engineers seeking a proven conductive silicone option for EMI gasketing.
  • Precision-Cut by SRP – Converted into custom gasket geometries for enclosures, access panels, connector interfaces, and other EMI sealing applications.

Typical Applications

  • Electronic and RF enclosures requiring EMI suppression
  • Military and aerospace housings
  • Connector gaskets and interface seals
  • Communication systems and radar electronics
  • Industrial control equipment subject to electromagnetic interference
  • Shielded panels, doors, access covers, and frame gaskets
