The effect of silane coupling agent (Si-69) on thermoxidative stability of butyl rubber compounds

Thermal analysis and the ageing studies of butyl rubber (IIR) compounds have been carried out in order to assess the effect of a silane coupling agent, Bis-(3-triethoxysilylpropyl)tetra sulphide (Si-69) on thermal and thermoxidative stability of IIR. The thermal stability of the raw rubber remained uneffected on adding Si-69, whereas the thermoxidative stability was enhanced. Similar behaviour, though to a lesser extent, has been observed for compounded rubber. The ageing properties and service life are also improved with Si-69. A suitable mechanism has been proposed.
