Electromagnetic Toleration of Plastic Cases

Untreated plastic cases provide no or only inadequate EMI (electromagnetic interference’s) and ESE (electrostatic discharging) protection.

Due to the application of conductive surface covers it is possible to reach a totally new electromagnetic toleration (EMI). These protection covers are often used for electronic devices (computers and peripherals, medical and electronic devices, measurement and control engineering etc.).

The products can be based on copper, nickel, graphite or silver. An  UL-listed EMC conduct lacquer based on copper is often preferred; it provides a very good cushion quality and a high electromagnetic absorption in a wide frequency range.
