Abstract

Abstract: The objective of this paper is to identify the existence of urethane linkage, soft segment polyol and hard segment polyurea in polyurethane from palm oil-based polyol. 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 of polyurethane yielded is flexible polyurethane foam with glass transtion temperature of 23.9°C for soft segment and 65°C for hard segment polyurea, respectively. Therefore, it is possible to develop polyurethane from palm oil based polyol. Future research should focus on its commercial applications for industrial use and benefits
