Influence of various modifiers on the properties of recycled polyethylene, approaches to plastic recycling

Abstract

The article presents the results of the research carried out by the specialists of POLYPLASTIC Group LLC on the modification of recycled polyethylene with small amount of various chemical additives. The results of the evaluation of the viscosity, physical and mechanical properties of the obtained materials, as well as rheological curves, are presented. Data on the introduction of antioxidants into recycled materials to improve thermal stability after recycling are presented. The use of this modifiers makes it possible to increase or decrease the viscosity of the material, while the strength properties are practically unchanged. The possibility of cross-linked polyethylene recycling is shown, data on the viscosity and physical and mechanical properties of the obtained granulate are given, which are close to the properties of extrusion grades.
