Effect of different chemicals and additives used in producing polyester foam was investigated. Reference samples were
produced from polyol, toluene di isocyanate (TDI), amine stannous octoate distil water, and silicone oil using laboratory
mix formulation based on 500 g polyether based polyol. Other samples were produced by consecutively varying the
content of all the additives with the exception of polyol. Standard sample dimensions for density test, indentation test,
compression set test, tensile strength and elongation tests were produced from the samples. The various tests were carried
out on the samples using the ASTM-D3574 standards. It was observed that the degree of indentation affects the
value of indentation hardness and increasing the percentage content of TDI results in acceptable compression set value
for the polyester samples. It was concluded that Holding all other parameters constant, reducing the water content and
increasing the TDI content will yield polyester foam of optimum properties.
