The study investigated the effect of eggshell and groundnut husk as fillers on flexible polyether foam. The fillers with the mesh sizes of 50µm respectively were mixed in the ratio of 50-50. Varying percentages of the mixed fillers ranging from 10%, 20%, 30%, 40% and 50% were incorporated into the polyether recipes in the appropriate foam formulations and foam samples were produced. The unfilled foam (0%filler) served as the standard control sample. The physico-mechanical test carried out on the foam showed increase in the properties such as density, compression set test, indentation hardness test, tensile strength test and decrease for elongation at break test as compared to the unfilled foam. The scanning electron microscopy result showed the cell sizes became smaller and concentrated with an irregular shape as the filler load increased, thereby making it denser and thicker. Eggshell and groundnut husk can be used in the production of flexible polyether foam since they are organic materials. They can enhance the mechanical properties and biodegradability of polyurethane product. The use of fillers in polymer composite will help in sanitizing the environment by reducing landfills and producing eco-friendly waste and also it influences cost positively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
