                  Silicone is widely regarded as a thermally stable and non-degrading material, largely because of its strong Si-O backbone. While the chemistry is fundamentally sound, this belief often oversimplifies how silicone actually behaves in real industrial environments. In practice, silicone stability is not a material constant. It is a process-dependent variable\u2014one that is frequently mismanaged when teams equate \u201cno visible damage\u201d with \u201cno functional degradation.\u201d From a manufacturing perspective, silicone does not fail dramatically. It fails quietly, through changes in physical properties driven by thermal history, residual volatiles, and post-curing discipline.
