Conductive Seals & EMI / RFI Shielding
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.
