All Seals has experience in the providing of precisionEMI RFI shielding gaskets and conductive gaskets and seals for a wide variety of industries and applications. Custom Gasket’s technically-oriented professionals have extensive knowledge of EMI RFI shielding and conductive materials and can assist you with your material selection. All Seals takes pride in its ability to consistently produce precision EMI RFI shielding gaskets guaranteed to meet your specifications and function perfectly within your application.
It is important to shield, modern electronics from electromagnetic interference (EMI) and radio frequency interference (RFI) emitted by electrical circuits. This interference can corrupt performance, but can easily be eliminated by using a gasket made of conductive or absorbing material. Electronic devices must also shield themselves from outside interference, which can be accomplished through the proper use of an EMI RFI conducting gasket. All Seals works directly from your blueprints in order to provide a quality shield in the form of an EMI RFI or conductive gasket.
All Seals uses special materials that either conduct or shield electricity while still providing a sealing barrier. This will ensure that your gasket will meet and exceed your expectations. There are many types of conductive materials to choose, including both rubber and foam, which have all the normal sealing properties of traditional gasket materials. Most rubber EMI materials are a multi-material compound consisting of both rubber and conductive filler. When blended properly, these two materials provide both an excellent electric and environmental seal. These rubber EMI materials also provide more conductivity and corrosion resistance options because you can choose which filler material to use for your unique application.
Rather than conduct electricity, some materials absorb EMI. These materials convert the electricity they absorb into heat and dissipate it in a controlled manner, instead of absorbing the EMI completely and grounding.
All Seals converts its conductive silicone EMI gaskets from silicone rubber or fluorosilicone rubber embedded with silver-plated aluminum, silver-plated glass, silver-plated nickel, silver-plated copper particles, nickel-graphite particles or conductive carbon. The incorporation of silicone with metallic, conductive microscopic particles creates a compound capable of providing high electrical conductivity, broadband shielding and moisture sealing. We manufacture electrically conductive gaskets that provide sealing solutions for critical applications. These materials provide protection from the environment, electromagnetic interference, electrostatic discharge, and radio frequencies. We utilize rubber / metal hybrid compounds for your applications in the aerospace, semiconductor, and medical device industries.

Wire Mesh Conductive Gaskets (Silicone Rubber)
Wire mesh conductive gaskets are dual purpose composite EMI shields and a pressure seal in thin sheet form. The EMI shielding is provided by woven aluminum mesh, impregnated in the mesh is neoprene or silicone rubber. These gasket materials are intended for use in applications where space is limited or joint unevenness is less than 0.002” in (0.05 mm). The silicone or neoprene elastomer performs under pressure by protruding through the mesh to give sealing protection. The material can be cut easily into gaskets of any shape and size with a minimum nominal thickness of 0.016” in (0.40 mm). These gaskets tend to be less costly than conductive silicone materials making them a great choice for lower cost effective EMI/RFI shielding and environmental protection.
Conductive Foam EMI Gaskets
Conductive foam EMI gaskets consist of a polyester textile yarn uniformly plated that provides X, Y, and Z axis conductivity. They are easily compressed, have excellent mechanical wear properties, have very high shielding performance (60 – 100dB), have high level of flame resistance (UL94-V0, HB certified & RoHs compliant), are easily mounted using pressure sensitive adhesive (PSA) and are able to operate at higher frequencies due to no gaps in their construction. All Seals is a recognized leading converter of conductive rubber and foam products. Below is a list of conductive wrapping materials available to suit your requirements:
Nickel/Copper/Nickel plated – Excellent shielding effectiveness and anti-tarnish
Carbon/Nickel/Copper/Nickel plated – Provides good levels of waterproofing
Gold plated – Excellent conductive and premium shielding performance levels
Aluminum Foil – Low cost alternative with good thermal dissipation properties
SOFT-SHIELD® Foam Based Gaskets
Chomerics SOFT-SHIELD® EMI gaskets are available in a assortment of materials to meet specific applications; including conductive yarn over foam, knitted wire over foam, foil/fabric and conductive fabric over foam, and high performance fabric-wrapped foam. SOFT-SHIELD 4800 represents Chomerics latest innovation in soft foam based EMI shielding technology.
