We report on the rigid polyurethane foam (RPUF) with varying amount of blowing agent. The effects of blowing agent in the formation of polyurethane will be characterized using scanning electron microscopy (SEM) and fourier transform infrared (FTIR) spectroscopy. SEM images revealed that varying the amount of blowing agent will significantly change the surface morphology of the resulting RPUF. The average cell size of the RPUF increases with increasing amount of blowing agent. Moreover, FTIR results revealed the presence of functional group related to formation of urethane bonds such as N-H, C=O, C=N and C-O-C stretching suggesting that polyurethane foam was successfully synthesized. This simple and straightforward process of RPUF using water as blowing agent will be economical.

Rigid polyurethane foam (RPUF) used for imitation wood is typically prepared by using 1-dichloro-1-fluoroethane (HCFC-141b) as a blowing agent. However, this chemical is a hydrofluorocarbon which severely causes ozone depletion to the atmosphere. In this study, a more environmental-friendly RPUF was prepared by using distilled water and cyclopentane (CP) as alternative blowing agent. Several properties of the prepared RPUF were investigated and measured such as density (kg/m3), surface hardness (Durometer, type D), and glass transition temperature (°C) using differential scanning calorimeter (DSC). It was found that when the amount of blowing agents decreased, the foam density was increased as well as the surface hardness. The developed RPUF with CP co-blown has higher surface hardness and glass transition temperature compare to pure water-blown RPUF at the same density (353 kg/m3). And the new RPUF produced has a good potential to substitute for a conventional RPUF.
