What is silicone sealant’s melting point?
Engineers and designers who searching for an exact temperature point at which silicone rubber can begin to degrade in application often ask this question “what exactly is the melting point of silicone sealant”? It is understood that while most plastics will begin to melt at high temperatures, silicone does not have a melting point and remains solid until combustion occurs. Silicone is not a flammable material. It can catch fire and burn, but only at extremely high temperatures. Silicone has an ignition temperature of 842 degrees Fahrenheit (450 Celsius) At high temperatures (200-450oC), silicone rubber (not silicone sealant) will slowly lose its mechanical properties over time, becoming brittle. In the majority of cases, experts are unable to provide a clear response without first discussing the atmosphere in which the silicone will be used and the temperature(s) to which the substance will be exposed. Adding flame retardant additives to the manufacturing process is a common way ...
