Morphology, Thermal Degradation and Dynamic Mechanical Properties of Polyurea used as Explosive-Proof Elastomer

Abstract It is well known that the blast affected the explosion and terrorism, not only human life, but also the building structure. In order to prevent these, protective materials are developed. One of them is polyurea. In this work, the elemental composition and microstructure of the selected polyurea sheet samples are characterized. Thermal, dynamic mechanical, tensile, and hardness properties are also studied. It is found that carbon and oxygen are the main compositions, while silicon, fluorine, and titanium are presented as minor ones. The modulus and loss factor increase as the frequency and temperature increase. The elongation property is over 100% and the hardness is around 90 Shore A.
