Characterization and synthesis of polyether polyol to be used in production of polyurethane rigid foam

In this study, the aim is to obtain a rigid polyurethane foam material on the purpose of using it in the heat insulation. Accordingly; first of all the polyether polyol has been synthesized by plunging initiator and propylene oxide into reaction accompanied with a catalyzator. The optimization of the synthesis of the polyether polyol has been realized and the synthesized polyol characterization has been practiced with Fourier Transform Infrared Spectroscopy (FT-IR), Gel Permeation Chromatography (GPC) and Determination of Hydroxyl Value (ASTM E 1899). Rigid polyurethane foam has been gained by plunging isocyanate (Difenilmetan-4, 4'-diizosiyanat) into reaction with the synthesized polyol by one-shot technique. In order to examine the physical and the mechanic characteristics of the obtained rigid polyurethane foam, the analysis of the scanning electron microscope (SEM), thermal conductometry, test of the compressive strength, the measurement of the open-closed cell rate and the foam test have been made.
