Morphological and Physico-Thermal Properties of Soy-Based Open-Cell Spray Polyurethane Foam Insulation Modified With Wood Pulp Fiber

Mustafa Khazabi, Mohini Sain

Abstract


Replacing polyether and polyester polyols with soy-based vegetable oil, using water as a blowing agent, would provide environmentally friendlier spray foam insulations, making buildings safer places to live in. The objective of this work was to produce sustainable open-cell spray polyurethane foam insulation from soy-based polyol and enhance its properties by incorporation of wood pulp fiber. The effect of wood fiber in composite foam was investigated in terms of its morphology by Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), and Thermo-gravimetric Analysis (TGA). The changes in foam properties such as bulk density, compressive strength, water vapor permeability and thermal resistance were observed. Addition of fiber as reinforcement improved bulk density, moisture permeability and thermal degradation, but slightly reduced the comprehensive strength and thermal resistance of the insulation foam.
