Excellent thermal stability is one of the key features of polydimethylsiloxanes (PDMS), which make them suitable for a wide range of applications. Thermal resistance of silicones at high temperatures is due to the inherent strength and flexibility of the polymer backbone. In particular, the Si-O bond has high bond dissociation energy (108 kcal/mol) and low energy barrier to bond rotation. While the thermal degradation mechanism of linear PDMS is well understood [1,2], the thermal degradation mechanism of cross-linked PDMS networks has not been studied yet. Therefore the goal of this study is the elucidation of the thermal degradation mechanism of cross-linked silicone elastomers (Figure 1) through the investigation of their thermal degradation behaviour and degradation products.
