Some Physical and Mechanical Properties of Recycled Polyurethane Foam Blends

Blends of secondary rigid polyurethane foams (RPUFs) with soft polyurethane foams (SPUFs) were in vestigated. The effect of SPUF content and its chemical nature on some physical and mechanical properties of the blends was evaluated. Owing to the stronger intermolecular interaction and higher values of cohesion energy, the blends of RPUFs with polyester SPUFs showed higher mechanical properties than those with polyether SPUFs. The density, hardness, ultimate strength, and the tensile, shear, and flexural moduli increased, while the impact toughness, ultimate elongation, and damping characteristics decreased with increasing RPUF content in the blends.
