There is a higher demand for naturally derived organic fillers than for conventional inorganic fillers, which have a greater environmental impact. For example, cellulose is commonly available organic filler ; however its dispersion in the matrix such as polymers may be poor depending on the base material, and it cannot even form a complex. In this study, we focused on paramylon, which is a naturally derived polysaccharide having unique physical properties. Using a universal testing machine EZ Graph-10 kN, we compared the physical properties of a compound containing 100 polypropylene, 20 paramylon, and 5 maleic-acid-modified low-molecular-weight polypropylene resin as a compatibilizer, with a filler-free compound of the same formulation It was found that with increasing paramylon, the maximum point stress and elasticity increased, while the maximum point displacement decreased. This result suggests that paramylon is a novel prospective filler material.
