Conductive Seals & EMI / RFI Shielding

Conductive Seals

Jonal has specialty elastomer formulations that are electrically conductive.

Applications include Electro-Static Dissipation (ESD) and shielding.

Conductive elastomers can be molded in a variety of shapes and sizes, and can be bonded to metal substrates to suit specific mounting options.

EMI / RFI Shielding

Electro-Magnetic Interference (EMI) and Radio-Frequency Interference (RFI) shielding are a specialized category of conductive seals. EMI / RFI shielding technology is a key element in creating low-observable or stealth systems.

EMI and RFI shielding products manufactured by Jonal are made from specialty elastomers containing precious metal fillers. These fillers impart high electrical conductivity / low resistance while maintaining flexibility. Seals of this type are used to protect sensitive electronic equipment in three ways:

  • To attenuate impinging external radiation (RADAR, EMP etc.) from entering the enclosure
  • To prevent internal radio frequency signals escaping from the enclosure
  • To provide environmental sealing against dust, moisture, etc.
