The article discusses the creation of elastic self-adhesive radio absorbing materials for the frequency range of 4.5 – 6.0 GHz. In recent decades, technologies related to the emission of electromagnetic energy into the environment have been rapidly developed. In 1996, the World Health Organization first introduced the concept of "Electromagnetic environmental pollution". The electromagnetic field is a biologically active, biotropic factor that, under certain conditions, can cause pathological changes in the functioning of the human body. An effective way to meet the requirements of electromagnetic ecology and safety is to reduce electromagnetic radiation to an acceptable level through the use of protective materials. Analyzing the composition of existing protective materials, it is obvious that the shielding (reflecting) properties dominate over the absorbing ones. Under the conditions of the modern magnetic environment, the need for absorbing materials is great, which is explained by the need to exclude the influence of re-reflections on the complication of the structure of the electromag-netic field, which leads to an increase in the total surface irradiation of the object. In this regard, based on the ethylene-propylene sealant "Abris" produced by LLC "Plant of sealing materials", Dzerzhinsk, Nizhny Novgorod region, a radio-absorbing material was developed. To absorb electromagnetic radia-tion, UFM-4HD carbon fiber and metal scale are introduced into it. It is shown that their introduction into the composition of the composite leads to the absorption of electromagnetic radiation by 75-78%. The material is designed to protect premises and equipment from electromagnetic radiation.
