As technologies such as 5G and autonomous vehicle markets continue to advance, protecting sensitive electronics systems from electromagnetic interference (“EMI”) is crucial. EMI Shielding products prevent electromagnetic pollution that can affect highly sensitive components and signals and are found in many applications, including data transmission systems and shielding between components and functions.
EMI Shielding materials are used in many industries, including:
- Aerospace & Defense
- Automotive
- Electronics
- Telecom
- Industrial
- Medical
What Solutions Are Available?
PAS offers many solutions for application that require EMI shielding:
- Electrically conductive adhesives
- Low modulus elastomer
- Cured-in-place Gasket (“CIPG”) and Formed-in-place gaskets (“FIPG”)
- Coating
It can be dispensed, spray-coated, stamped, and paint brushed.
Dow recent patented innovation – DOWSIL TM EC-6601 Electrically Conductive Adhesive – provides stable electromagnetic shielding over the application’s lifetime. The product can be used as adhesive, sealant, gasket, PCB grounding, or electrical connection. It has shielding effectiveness of 85dB at 1 kHz – 3GHz
