The struggle between the world and electromagnetic interference (EMI) is endless. EMI consistently attempts to sabotage our most critical technologies in the aerospace, mass transit, medical, and military industries.

EMI engages us through maneuvers such as: radio transmitters, electric motors, power lines, fluorescent lights and computer circuits. Through these maneuvers, EMI generates electromagnetic disturbances, signals and emissions that cause undesired responses or degradation of performance in electrical and electronic equipment. This occurrence leads to system malfunctions and failures, which can threaten the performance of life support devices, military radio frequencies and aircraft flight controls – to name a few examples. Malfunctioning or failure of these types of systems, triggered by EMI, can be problematic, dangerous and life-threatening.

Particle-Filled Silicones for EMI Shielding and Environmental Sealing

Particle-filled silicones are elastomeric compounds that combine the advantages of silicone with electrical properties of metals. 

Some designers have concerns about using particle-filled silicones.  Silicones have desirable material properties, but loading a high percentage of particle filler into the rubber in an effort to increase conductivity can result in negative tradeoffs.  Typically industry professionals worry that particle filled electrically-conductive silicones are:

  • too hard
  • too brittle
  • too expensive
  • have long lead times
  • limited by mold size dimensions
  • not thin enough for newer, thinner designs
