Foam polyethylene is an effective insulating material in systems of frame and frameless buildings, floating floors, and technical thermal insulation. The products based on this material enable to obtain seamless insulating shells, which significantly reduce heat loss through joints. The use of recycled polyethylene for the production of foamed polyethylene is advisable both from the point of reducing the cost of the material itself, and from the point of preserving the environment. The aim of the work was to assess the possibility of using recycled polyethylene for the manufacture of foamed polyethylene, taking into account the possible application of modifiers and varying the foaming modes. The results of the experiment made it possible to evaluate the influence of prescription and technological factors on the properties of products. The implementation of optimization solutions made it possible to construct a nomogram that allows predicting the properties of products and establishing the optimal costs of the main components. The optimal interval of consumption of recycled polyethylene has been established, which is 20 … 25%. The properties of such a material practically do not differ from the properties of products made from foamed polyethylene that enables its application in all insulation systems where pure foamed polyethylene is used.
