The method used to produce this polyurethane is the one-shoot method. In this method, palm oil-based polyol and additives such as water, surfactant, catalyst and methylene chloride was mixed in a reactor, then toluene diisocyanate (TDI) was poured intothe reactor and stirred. Polyurethane produced was then poured into a cast and cured. The structure of polyuretan yielded was analysed by using Differensial Scanning Calorimeter to investigate soft segment dan hard segment polyurea. Fourier Transform Infra Red (FTIR) Spectroscopy was used to identify the existence of urethane linkage. Results indicated that the type o
