Abstract

A major section involved in the production of flexible polyurethane foam (FPF) is the chemical proportion formulation. This section determines the quality of the foam to be produced. Quality control in FP F production cut across this section, as wrong chemical formulation yields a different foam as compared to the desired foam. This work developed a model capable of generating chemical formulation for a specified foam density. Chemical formulations for four different foam densities were obtained and compared with manual real life data obtained from a foam manufacturing industry located in the North Central part of Nigeria. Using a two-sample t-test, the result shows that there is no significant difference between the model result and the real life data. 2-tailed significance of 0.215, 0. 088 and 0.124 were obtained for polyol, TD/ and water respectively and were seen to be greater than the level of significance (0.05).
