RobZorb™ GDS is a two-part dispensable elastomer absorber designed to suppress cavity resonances, surface waves and RF coupling in high-frequency applications. It is particularly well suited for hard-to-reach areas where traditional sheet absorbers can be difficult to install or may not provide complete coverage.
Its low-viscosity, self-levelling formulation allows the material to be applied using commercially available dispensing equipment, ensuring complete filling of complex cavities and geometries. RobZorb™ GDS cures in place and forms intimate contact with surrounding surfaces, eliminating the need for liner removal or labour-intensive placement processes. This simplifies manufacturing, reduces waste and supports shorter production cycle times.
Optimised for the 18 to 35 GHz frequency range, RobZorb™ GDS provides high magnetic loss for effective microwave absorption. The material is based on the same proven absorber technology used in Eccosorb™ GDS sheet absorbers, enabling designers to replace or complement conventional absorber materials while maintaining reliable RF performance.
