Fabric-Over-Foam: Soft Shield 3500

The SOFT-SHIELD® 3500 fabric over foam (FOF) product family is a group of low-closure force EMI/EMC gaskets. SS3500 offers a low cost/low closure force competitive solution for EMI shielding and electrical grounding in shear and compression.
The SS3500 product family is comprised of conductive nickel plated copper polyester taffeta fabric wrapped around open cell urethan foam. This wrap around technology grounds the gasket from point to point, ultimately eliminating an EMI/EMC gap.

Product Highlights:

  • Low closure force
  • Low contact resistance
  • Good low compression set properties

SS3500 typically requires less then 1lb / in (0.175 / mm) closure force, making it effective for low closure force applications. SS3500 takes less than 15% compression set. This is less than most other FOF’s on the market resulting in reliable/repeatable shielding performance. SS3500 is an excellent alternative shielding solution to traditional spring finger type products.

The SS3500 product family is one of the most versatile EMI FOF products offered to the market. Depending on mechanical and shielding requirements, the SS3500 can be made with different conductive jackets:

  • Nickel-plated copper taffeta
  • Nickel-plated copper rip-stop polyester

New profiles are designed and released to the market on a regular basis. Profiles are engineered to optimize mechanical form, fit and function while optimizing electrical performance. This technical data sheet addresses the most common type FOF Parker Chomerics has to offer to market. Contact Chomerics for any other special design requirements and an updated profile list.
