Influence of cenosphere particles on thermal properties composites of silicon rubber

Abstract

The study presents the investigation results concerning the thermal properties of non-cross-linked and cross-linked silicone rubber with organic peroxide. The rubber was filled with mineral fillers such as cenospheres, including cenospheres covered with iron, attapulgite, wollastonite, aluminum hydroxide and silica. The thermal stability of the silicone rubber was considered from the point of view of the mineral fillers used, particularly taking into account the modern cenospheric filler. Thermal analysis was carried out under both air and a neutral gas at temperatures ranging from 120 to 700 °C. The activation energy value of the silicone rubber destruction was determined with the use of the non-isothermal method of Flynn–Wall–Ozawa.
