Radio Frequency Absorbing Materials

Called by many names in the industry, the RF or Radio Frequency Absorbing materials have one important purpose despite the different nomenclatures, and that is to reduce or attenuate the energy that is emitted from a magnetic field so as not to cause any interference with any operation on a system. It was first widely used in worldwide military forces but as the years passed; its applications have greatly increased through time. Such Radio Frequency absorbing materials, such as the RF Absorbing Foam, are now parts of the important aspects of consumer electronics, computers and notebooks, wireless devices and systems, and a whole lot more.

The Mast Technologies that is based in San Diego, California is one of the leading designer, innovator, and manufacturer of these RF and microwave absorbing materials. They take pride in being able to offer undeniably prompt and highly effective solutions to your absorber needs as a customer driven organization. As their clients, the Mast Technologies will take care of you from the selection of products up to the post sale support that you will need.

Mast Technologies sells exceptional products and whatever absorbing materials it is that you need, you are sure to find it on the said company.

One of their highly regarded products is the RF absorbers, which are available in different material types, such as the flexible and thin magnetically loaded rubber absorbers, the flexible dielectric foam absorbers, as well as the sprayable and cast absorbers.

Under the magnetically loaded rubber absorbers, there are more products specifically made for their specific purpose too. Some of these are the cavity resonance absorbers, tuned frequency absorbers, surface wave absorbers, and the low frequency absorbers. As for the dielectric foam absorbers, Mast Technologies have reticulated foam, convoluted and lossy foam absorbers. Lastly, under the sprayable and cast absorbers, the company has the absorber inks, caulks and coatings.

Aside from these radio frequency and microwave absorbers, there are other exceptional products from Mast Technologies, such as the EMI, or electromagnetic interference, shielding, where you can find the oriented wire elastomer as well as their conductive caulk. They likewise have RF absorbing assemblies, such as the cellular backlobe suppressors. The company also offers a variety of coatings, which come in different forms, such as the absorptive, conductive, and resistive type. One of the significant innovations and developments of Mast Technologies is the family of various high temperature materials, which are very useful for the protection of certain consumer products that degrades over time and temperature.
