Why ETS-Lindgren Should be your Choice for Microwave Absorber Superior Design Capability With a wide range of products, our standard microwave absorbers will fit most needs. However, some applications have special requirements that can only be met with a custom product. That’s where ETS-Lindgren excels. Instead of “cut-and-try” experimentation, our engineering staff uses powerful workstations running advanced numerical modeling programs to develop the right solution. Next, prototypes are made and the design is tested. Results become part of a valuable feedback loop for refining our designs further....

Large Capacity Production sample testing assures standards are met. Flammability ETS-Lindgren’s Rantec Brand CL combustion limiting polyurethane absorber sets the standard for material fire retardancy. We meet the following U.S. Government and commercial flammability specifications, as verified by an independent testing laboratory: Our 8,639 m2 (93,000 ft2) manufacturing facility in Durant, Oklahoma is the world’s largest, capable of producing over 24,777 m3 (10.5 million board feet) of absorber per year. Capacity like this has allowed us to supply absorber for some of the biggest chambers ever...
