Have you ever heard of conductive elastomer gaskets? If not, you aren’t alone, but this type of gasket (also called EMI gasket) plays an important role in military, aerospace and commercial applications today? But what is the material and why is it important? Let’s examine this issue a little more closely to see.
What are Conductive Elastomer Gaskets?
An elastomer is polymer (long chained molecules) which has many of the properties of rubber. When stretched, it becomes thin and then returns to its original shape. However, elastic polymers are good insulators and to give them properties of a conductor, metallic particles and carbon are added to the raw materials. So, a conductive elastomer is a rubberlike material capable of conducting electricity.
Some conductive elastomers are very sensitive to pressure. For example, increasing the pressure changes the conductivity and vice versa. In fact, they are sometimes used in pressure sensing equipment. This kind of material is often used to create large conductive sheets and EMI gasket material. EMI stands for electromagnetic interference. The gaskets can be used to prevent the build-up of static electricity which can be disastrous to many types of computer hardware.
The Benefits of Electromagnetic Interference Shielding Materials
EMI shielding sheets and gaskets are easy to create and readily available. Plus, you will enjoy these additional benefits:
* Flexible conductive material
* Versatile – can be created with extrusion or cast
* Cost effective
* Excellent performance
Dual Purpose
When you use an EMI gasket you have the benefits of electromagnetic interference shielding. In addition, its polymer properties make it excellent protection from environmental factors. They can seal against moisture and help contain pressure.
Choosing the Right Source
When you need a provider for EMI shielding products go with a company that has many decades of experience and a worldwide presence. This ensures high quality and dependability.
