Blend dibuat dengan rasio berat NR/PP 10/90, 20/80, 50/50, 60/40 dan 70/30 dan komposisi sulfur 3 dan 5 phr (per hundred rubber). Proses pencampuran dilakukan pada suhu 180 oC dan kecepatan rotor 60 rpm. Analisa morfologi menggunakan SEM (Scanning Electron Microscope) dan DSC (Differential Scanning Calorimetry). Properti mekanik yang diukur meliputi tensile strength, elongation at break, izod impact, tearing dan hardness, berdasarkan standar ASTM. Didapatkan bahwa peningkatan rasio NR/PP menghasilkan distribusi partikel NR yang makin merata dengan ukuran yang makin kecil. Morfologi blend menunjukkan sistem dua fasa dan vulkanisasi fasa NR terjadi secara parsial dalam matrik PP. Peningkatan rasio NR/PP dan komposisi sulfur dapat meningkatkan properti elongation at break, namun menurunkan properti tensile strength, izod impact, tearing dan hardness. Elongation at break tertinggi yang dapat diperoleh adalah 70% pada rasio blend NR/PP 70/30 dan komposisi sulfur 5 phr.}, issn = {2407-5973}, pages = {71--77} doi = {10.14710/reaktor.11.2.71-77}, url = {https://ejournal.undip.ac.id/index.php/reaktor/article/view/1003} }
