Shield Seal Gaskets

Series No. 1500

MAJR Products’ Shield Seal gaskets are available in various material combinations and combo gasket sizes. Our mesh combo gasket materials and sizes provide assurance of protection against weather conditions, including temperature extremes, as well as against Electromagnetic Interference and Radio Frequency Interference leakage. Our standard EMI gasket materials conform to military (MIL) specifications. The elastomers (neoprene or silicone) are available with or without an adhesive backing.

The Shield Seal Strip, a railroad gasket, is used in applications such as electronic cabinets where this type of material is utilized around the doors of the cabinet to seal off stray EMI signals. The Shield Seal Strip is also used extensively to shield electronic boxes of various sizes and shapes.

Standard Products

Shield Seal Strip EMI Gaskets (1500 series) is a combination of wire mesh and an elastomer to form one product with excellent environmental and EMI/RFI shielding properties. It is used in applications such as electronic cabinets where this type of shielding gasket material is utilized around the doors of the cabinet to seal off stray electromagnetic and radio frequency interference.

Product Features:

  • Highly Customizable: Shield Seal is often used not only in strip form, but also as custom die-cut & mesh bonded gaskets. MAJR can convert our shield seal product into almost any configuration. Contact us regarding your custom application.
  • Protection Against Atmospheric Conditions: The various elastomer materials as provided by MAJR protect electronic equipment against moisture and dust under severe temperature variations. There is a proper elastomer for almost every condition. Special materials are available. Contact our application engineers to discuss your needs.
