“…Sureshkumar et al [33] have pointed out the excellent potential of EPDM as insulator regarding its ageing resistance, low-temperature flexibility, low erosion rate, and low specific gravity. EPDM typically starts to decompose at around 400°C [34]. It is preferred for military applications because of its outstanding ageing resistance characteristics.…”

“…It was highlighted that the ablation of insulator materials depend not only on its inherent properties but also on extrinsic conditions such as thermal, chemical, and mechanical factors related to theoretical or practical environment variables [34]. In this sense, a detailed work by Zhu et al [102] has indicated that the high degree of development of research on TPS is not only focused on materials but includes a thorough analysis of heat transfer coefficients and modeling.…”

This review addresses a comparison, based on the literature, among nitrile rubber (NBR), ethylene-propylene-diene-monomer rubber (EPDM), and polyurethane (PU) elastomeric heat shielding materials (EHSM). Currently, these are utilized for the insulation of rocket engines to prevent catastrophic breakdown if combustion gases from propellant reaches the motor case. The objective of this review is to evaluate the performance of PU–EHSM, NBR–EHSM, and EPDM–EHSM as insulators, the latter being the current state of the art in solid rocket motor (SRM) internal insulation. From our review, PU–EHSM emerged as an alternative to EPDM–EHSM because of their easier processability and compatibility with composite propellant. With the appropriate reinforcement and concentration in the rubber, they could replace EPDM in certain applications such as rocket motors filled with composite propellant. A critical assessment and future trends are included. Rubber composites novelties as EHSM employs specialty fillers, such as carbon nanotubes, graphene, polyhedral oligosilsesquioxane (POSS), nanofibers, nanoparticles, and high-performance engineering polymers such as polyetherimide and polyphosphazenes.
