Polyurethane foam insulation based of environmentally friendly chemical components using novel foaming agents was obtained. Physical and mechanical properties of thermal insulation was investigating. The infl uence of foaming agents on insulation properties and production technology of preinsulated pipes, fi ttings and polyurethane shells was studied. It is shown that when using water and dimethoxymethane, polyurethane foam insulation has quite good physical and mechanical properties and can be used in the production of PI pipes, shells and fi ttings.
