EMI / RFI Shielding Foams and Foam Materials
from Dexmet® Corporation, a part of PPG’s engineered materials division
Cuming Microwave manufactures a family of flexible carbon loaded microwave and radar absorber materials. These are all electrically resistive materials which attenuate RF energy through ohmic loss. These Carbon based microwave absorbers such as C-RAM MT have high dielectric loss over a very broad... [See More]

from Dexmet® Corporation, a part of PPG’s engineered materials division
Often, when radio frequency sources are located inside a shielded cavity, the RF energy can resonate within the cavity, and interfere with the signal or create crosstalk with other adjacent elements. Microwave absorbers can be strategically placed within the cavity or housing to attenuate resonances... [See More]
