Bomb is one of the favored weapon of terrorists for destroying and disrupting operations. Since the series of bomb attacks after nine eleven on various buildings of the world, research and development of antiblast material becomes a demand. keeping in view that need, in this book a polymeric nano material is prepared, tested and compared with the materials used usually for the purpose of blast resistance. Castor oil and HTPB based Polyurethanes samples are prepared and tested for microphase segregation, tensile strenght, modulus, Tg with UTM, DMTA and Autodyne simulation. Selected antiblast polymer shows higher values of tensile strenght and lower Tg without sacrifycing the elongation values so shows to be a better blast resistance nano polymer tuned to be absorb shock waves.
