Abstract
This study investigates the effect of various formulation variables on flexible polyurethane foam (FPU) of a density of 32 kg/m3. A detailed observatory analysis is performed to figure out the impacts of toluene di-isocyanate (TDI), water, surfactant, stannous octoate, and amine on unfilled 32-density FPU foam. The concentration of each component was manipulated to study its influence on the conduct and quality of the PU foam. For comparative purposes, an ideal foam with the correct amount of chemicals was developed. Comparative findings indicated that amine influences the porous nature of the resultant material, silicone plays a crucial role in delivering strength and stability to the cells and cell struts, stannous octoate provides the foam the strength required to sustain its structural integrity, and TDI has a significant impact on the hardness of the foam. Water additionally functions as blowing agent which is essential to initiate the foam to rise from liquid components to a compressible solid. Each ingredient has a considerable impact on the chemistry, foaming procedure, and physical characteristics of the finished material. This paper delivers an insightful comprehensive description to the novices in PU field, researchers and industrial professionals about the correlations between the FPU's structure, physical characteristics, formulation compositions, and chemical mechanisms.
Keywords: Polyurethane foam, surfactant, TDI, gelling catalyst, blowing catalyst
