High temperature resistant and rent burning silicone rubber and fillers were pressed into the adhesive sheet using the molding process. The material density is 0. 56 g/ cm3,specific heat is 1. 371 J/ ( g·k), thermal conductivity is 80 mW/ (m·K),tensile strength is 1. 87 MPa,and the elongation at break is 25%. At the wind tunnel environment of high enthalpy and low heat flow of certain type solid rocket motor,interface temperature is 70. 7℃ for 1 mm thick insulation material. And the apparent of specimens is complete with no cracking.
