Things You Should Know About Elastomer Products

Published / by mimin

Electromagnetic interference (EMI) can significantly affect the functioning of a wide variety of products and disrupt the lives of those who depend on them. In such environments as a hospital or the military, this can even have far-reaching consequences. Numerous sources, including computer circuits, nearby electronic devices, power lines and even switches can cause this interference. EMI shielding is effective in preventing these radiations from interfering with devices and even stops the cross talk within the circuit of a particular device.. Traditionally, these protective solutions were made of metal sheets. Constructed with steel, copper or aluminum, these shielding products offer robust protection against electromagnetic disturbances. However, they are very prone to deformation. The fault lies in their design, which emphasizes making the enclosure extremely snug in order to prevent EMI leakage. This creates excessive mechanical pressure, and under this pressure, the metal EMI shields tend to deform. Then, some metals are more susceptible to oxidation and rusting. Elastomer products can overcome these shielding challenges. Here are three major benefits of these sophisticated shielding products:

Improved Efficiency of EMI Shielding Gaskets

Made of different types of polymers and blended with metal fillers, new generation elastomer products ensure superior EMI shielding. They also ensure a long performance life for the gaskets. An important thing to consider when selecting a conductive elastomer as an EMI shielding or environment seal gasket is galvanic compatibility. When you use two dissimilar materials, one of them tend to oxidize and fail to provide effective shielding in the long-run. The right gasket will offer the protection while undergoing minimum galvanic corrosion. Silicone shielding elastomers, that combine the properties of silicone rubber and metals, is often a good choice.


Apart from increasing gasket efficiency, elastomer helps tone down the compression that builds up within the gaskets. This in turn improves air circulation inside the gasket. You can customize elastomeric products cost-effectively to meet the needs of specific production environments. As a result, you can find corrosion-resistant and flame-resistant products in the market. Apart from being robust and corrosion-resistant, these products are high on aesthetic appeal.

Efficient Shielding of Military Electronics

Militaries across the globe rely on technologies to gain an edge over their enemies. From anticipating enemy tactics to responding to their attacks, they rely heavily on a host of electronic devices such as radios, sensors, cameras and unmanned tactical weapons. However, these devices are particularly susceptible to electronic jamming or intentional EMI, a threat that endanger the lives of those fighting it out on the battlegrounds. Elastomer shields offer guaranteed protection against such intrusions.

When it comes to protecting your applications from EMI disturbances elastomer products can help you achieve correct shielding effectiveness. While selecting a product, the first thing you need to consider is the appropriate shape or type of gasket. The next important criteria relates to the polymer material.

Different elastomer products are made of different types of polymers such as Silicone, Fluorosilicone and Ethylene Propylene Diene Monomer (EPDM). Each one works in specific kind of environments. The types of environment your products will interact with will determine the type of polymer that you should opt for.
