Abstract

This work studies the effectiveness of local raw materials (coconut and palm kernel shells) as fillers in flexible polyether foam. Varying loads of the materials, such as 5%, 10%, 15% and 20% were incorporated into the foam recipes. The following properties, density, porosity index and tensile properties of the foam samples produced were compared with standard (10% CaCO3) foam sample. The results showed that the densities of the samples increase with increase in filler load, the samples filled with palm kernel shell showed the best results. In all the 15% and 20% foam samples showed better properties than the commercial filler used as standard. The porosity index of the foam samples filled with the novel fillers decreased when compared with the standard. The tensile properties such as breaking force, elongation at break and tensile strength vary with increase in filler load.
