Recycling of Industrial Polyurethane Residue and the Characterisation of its Properties

Abstract

The globalisation process has forced manufacturers to produce higher quality products with less environmental hazard. The newly developed industrial products produce residues, which pose challenges for recycling. In this work, we present the mechanical recycling of the industrial polyurethane residues incorporated in different proportions with polyurethane resins. Effect of temperature in the process and proportion of residues were considered for the process development. The products obtained in different proportions (weight of new resin: weight of residue) 1:4, 1:8, 1:12.5, 1:20 have been characterised by mechanical properties, resistance to abrasion and hardness which are required for the possible applications of the developed product.
