Improving energy efficiency and energy saving in refrigeration technology depends largely on the use of modern thermal insulation materials in the thermal insulation structures of refrigeration pipelines. The article presents a comparative analysis of the thermal characteristics and operational properties of heat-insulating materials used in refrigeration. The features of RUFLEX thermal insulation materials based on foamed synthetic rubber produced from domestic raw materials and their compliance with the requirements of energy efficiency, durability, operational reliability and safety are considered.
