• Electromagnetic Shielding

Electromagnetic interference (EMI) can disrupt electronic devices, equipment, and systems that are used in many vital applications.

The severity of the problem is a major issue that has called for legislation in all of the world’s major industrial centres, to ensure that electronic equipment is properly shielded from extraneous radiation.

As the electronics industry has expanded at an astounding rate over the last 30 years, electromagnetic compatibility (EMC) has grown into an increasingly important sub-sector.

In fact, the global value of this sector was reported to be $6.47 billion in 2016 and is predicted to rise by 7% each year, to a staggering $10.45 billion by 2023.

What is shielding technology?

In simple terms, shielding technology is necessary since all electronic devices are prone to emitting and receiving extraneous interference signals.

The issue is made worse by the fact that most housings for electronic equipment are made from plastic materials. Since these are inherently non-conductors of electricity, plastic enclosures do not offer any interference shielding in the way that metallic ones do.

To address this, plastic components of the enclosures need to exhibit some degree of electrical conductivity, even if only on the surface through specialist coatings.

Additionally, since plastics housings are frequently made up from a number of components, the joints where these parts come together must also be shielded, normally by conductive gaskets.

Our capabilities

Hart Materials has been active in the shielding market for over 35 years, supplying materials for both of these requirements – conductive pigments that can be incorporated into paint coatings and a range of materials used for conductive gasket manufacture.
