 Polyurethane, PU, foam with hybrid polyurethane graphite micro is suitable for lightweight structures applications due to its low weight and high strength, as evaluated through various tests such as compression, hardness, density, surface evaluation, and FTR analysis. The results showed that the expansion and shrinkage variations lead to different shapes at specific ratios, with PU foam with 2% graphite filler showing the highest results at a 4 to 1 ratio of 0.45 knots in compression tests. The highest hardness test result was 37.7 SHD, while density testing indicated the highest value from specimens with a 4 to 1 ratio of 0.077G slash CM3. FTR testing revealed that adding graphite as a filler alters the chemical bonds during the formation of solid PU foam, and surface observations showed that it influences the variation in material structure formation. Overall, the present combination is suitable for lightweight structures applications. This article was authored by Alvin Dio-Nigroho, Daffa Alandro, Harrianto, and others.
