Abstract -This study explores the properties and applications of synthetic rubber materials, particularly Rocket Case Insulation (ROCASIN), used in rocket motor casings. ROCASIN rubber, developed by ISRO, demonstrates exceptional thermal resistance, erosion protection, and mechanical properties, making it ideal for insulation in demanding aerospace environments. The research details the preparation, application, and curing processes of these rubber materials and discusses their performance under operational conditions. Key findings highlight ROCASIN’s superior thermal stability and erosion resistance, which ensure the safety and reliability of rocket systems. These results underscore the importance of material innovation in advancing aerospace technology.

Keywords: ROCASIN, thermal resistance, erosion protection, aerospace materials
