Abstract

Polyurethane foam (PUF) is formed by a chemical reaction of polyol and isocyanate. The aim of this work is to understand the effect of silicone on molded polyurethane. Silicone perform as surfactant, which influencing the interfacial level as well as within bulk. The method used was one step process, which are simultaneously carried out a blending polyol, TDI (2,4):MDI (4,4') (80:20), distilled water into different volumes of molding. The properties of molded polyurethane were determined by its polymer density, compressive strength, and cellular structures.
