Manufacturers of equipment for demanding applications such as wireless infrastructure, ruggedized scanners/readers, test equipment, defense and aerospace communications need reliable and cost-effective EMI / RFI shielding. Many are approved for military aerospace and spaceflight applications and typically combine good shielding effectiveness with light weight and low outgassing. They are offered in various forms, such as roll, sheet and peel and stick strips, that can be customized for a range of gasket solutions.

Recently, W.L. Gore & Associates has discontinued their GS2100 & GS5200 materials resulting in an increase in need of comparable materials for EMI / RFI shielding. 

MAJR Products has been a leader in EMI / RFI gaskets, shielding materials and ventilation panel products for over 25 years. Our new flame-retardant nickel based conductive silicone serves as a replacement for GS2100 & GS5200 materials or other conductive silicone requirements. 

Conductive silicone is a molded silicone filled with conductive inert particles. It provides high electrical conductivity, broadband shielding and moisture sealing. This material is manufactured in sheets, extrusions, strips and custom molded parts, making it the ideal replacement for GS2100 & GS5200.

MAJR Products offers reliable and cost-effective conductive shielding options for a wide range of EMI / RFI applications, providing high electrical conductivity, broadband shielding and moisture sealing. Our conductive silicone is manufactured in sheets, molded parts, strips and die-cut gaskets.
