DSH-750EP Durasorb™ Polystyrene Hybrid Absorber

ETS-Lindgren's DSH-750EP (Enhanced Power) Absorber is the latest evolution of ETS-Lindgren’s volumetrically loaded polystyrene absorber technology. It combines the advantages of the proven polyurethane based absorber performance with the physical properties of the polystyrene absorbers. DuraSorb is constructed using substrates with rigid, closed cell foams, which are loaded volumetrically and uniformly throughout the absorbers. DSH-750EP is ideal for antenna measurements and military standards testing.

Key Features

Frequency Range

The DSH-750EP provides a superior performance from 80 MHz to microwave frequencies. As a result of its optimized design, high performance is guaranteed, both at lower frequency bands and frequencies above 1 GHz.

Durable Construction

DuraSorb is manufactured by injecting uniformly loaded lossy materials in predetermined geometric shapes to produce the desired performance. After the lightweight substrates have been molded, they are shipped disassembled to job-sites for reduced shipping volume. Easily assembled at the site, finished absorbers are pressed and glued into a lightweight polystyrene universal mounting base on the walls and ceiling of the chamber. This method assures absorber rows are aligned with geometric precision. DSH-750EP measures 75 cm (29.5 in) height in pyramid shape.

Non-Hygroscopic Fire Resistant

DuraSorb is intrinsically non-hygroscopic due to its closed cell design. Furthermore, DuraSorb is engineered to have outstanding fire resistance. The material is treated additionally with environmentally friendly fire retardants beyond what is normally required for construction grade foams. DuraSorb material has been tested to meet the requirements of UL94 HBF and DIN 4102 B2.
