Abstract
Polyurethane (PU) foams are widely used in the industry, because of the unique physical properties ranging from soft to rigid. The research on polymer using renewables sources urged to be developed, without exception to PU it was supported by enormous resources which possible to replace the decline reserved for petroleum. This work was done by processing 2,4-toluene and 2,6-toluene di Isocyanate isomers to be blended to soy-polyols forming foam formation as a balanced reaction between blowing and gelation. The best catalyst concentration can control the reaction and the synergistic to chain extender can achieve foam stability. It was found the best concentration was 1% (v/v) sulfuric acid at temperature 600C. The method used in this research was a one-shot system. The goals were to determine the best process and production of PU. The chain extender used in this work was ethylene glycol, methanol, and butanol. The sulfuric acid was used for the catalysis and comparison purposes the butanol was catalyzed by bentonite. The morphology of the foam cellular, density, compressive strength was determined to support data.
