Foam Polyethylene Made of Recycled Polyethylene

Abstract The paper deals with the main principles of foam polyethylene production by the addition of recycled polyethylene and a modifier in the initial mixture. Obtaining of the modified foam polyethylene will accomplish two important tasks: solve the environmental problem of recycling polyethylene waste and reduce the cost of the material. The optimal consumptions of recycled polyethylene and a modifier were determined by using the methods of mathematical experiment planning. To predict the main characteristics of the modified foam polyethylene a special nomogram was worked out. The properties of the developed material were studied. Based on the obtained results, it was found that the modified foam polyethylene had quite proper physical and mechanical characteristics and could be recommended for use in insulation systems of frameless and frame buildings, as well as in floating floor systems.
