The Production of Polyurethane from waste Vegetable Oil-Based Polyols and Modelling of rheological Properties

  Polyols in polyurethane production is of great importance. The future will increase the production of polyols from renewable sources. The result of the reduction of fossil fuels will be important in the use of renewable resources. Especially important alternative which will expand polyols production from vegetable oils. Polyols derived from waste vegetable oil will be produced by epoxidation, hydroxylation and purification. In this study, the waste vegetable oil based polyols were produced the polyurethane with the catalysts. The thermal conductivity, density and mechanical properties of polyurethane were investigated. Also the produced polyols compared with commercial polyols with rheological properties as viscosity, temperature, shear stress, shear rate. The rheological properties of the polyols were modelling with developed equations based on experimental data.
