Abstract
In a company of the polymer branch, located in Jilotepec, State of Mexico, presents the need to solve some problems in the manufacture of polyurethane foam such as codes 25 STD BCQ and 64 FB, which must comply with a density and compression specific. We used the experimental design of Taguchi, which allows to design experiments that usually require only a fraction of the complete factor combinations, each factor can be evaluated independently, so that the effect of one factor does not influence the estimation of another factor. Seven factors were evaluated with two levels each: index of TDI, water, polyol, amine, catalyst Z-7, silicon and methyl chloride. To calculate the density (kg/m3), each of the samples obtained was weighed on an analytical scale and the volume of each one was obtained. The compression was measured on an Instron® universal machine. The new formulation optimized for the foam 25 STD BCQ achieved a density of 14-15 kg / m3 and a compression of 27-33 lbf., While the foam 64 FB achieved a density of 23-25 kg / m3 and a compression 58- 68 lbf., These results satisfactorily meet customer specifications.
