ABS-FLE

ABS-FLE is a thin polyurethane elastomeric absorber available in different thicknesses, typically 1, 2, and 3mm. This absorber material is specifically designed for use at the lower frequency range, typically between 1 GHz up to 12 GHz. Capable of being optimised by adjusting the thickness and magnetic loading, required attenuation can be achieved.

This high magnetic loading absorber provides a versatile solution for free space reflections, cavity resonance, and surface current suppression. While the urethane-based version is easy to bond, the silicone version (ABS-FLSE) offers a low-outgassing, high-temperature, and weather-resistant alternative for space or outdoor applications.

Typical applications include lining Aircraft ILS antenna housings, reducing reflections from metal structures, Satcom systems, and microwave housings. The material is durable, with a hardness of 90 Shore A, and can withstand service temperatures from -40°C up to 120°C (higher for the silicone version).
