​​ETS-Lindgren's type EHP (Extra High Performance) microwave absorber is designed for use over a wide frequency spectrum and has been used as an effective tool for the reduction of reflections from 30 MHz through 100 GHz. Each piece of absorber is fabricated of the highest quality urethane foam, which is cut into a precise bun configuration and impregnated with a conductive carbon using a proprietary formulation. 

After the addition of salts for the combustion limited version of the absorber, the buns are dried. The buns are then cut into precision shapes, such as pyramidal, wedge, and other geometrical shapes. Each piece of material is treated with a dielectric coating to provide a pleasant appearing, functional unit with superior performance properties.

Whether you need just a few pieces of absorber or a complete turnkey chamber, we have the experience and resources to help you with the right solution.
