The flame retardant performance of phenyl elastic putty is not its inherent property, but is achieved by adding flame retardants in the formula design. The specific performance can be adjusted according to the application requirements, and it has strong controllability and practicality overall.
From the perspective of flame retardant principle, the flame retardants added during the preparation process (such as phosphorus-containing, halogen-containing compounds or inorganic flame retardant fillers, etc.) will play a role through various mechanisms: some can form flame retardant coatings at high temperatures to isolate oxygen, some will release inert gases to dilute combustible components, and some will reduce the surface temperature of the material through endothermic reactions to delay the combustion process.
In practical applications, by optimizing the types and addition ratios of flame retardants, phenyl elastic putty can achieve different flame retardant levels. For example, in fields with extremely high safety requirements such as aerospace and high-speed rail; in ordinary industrial scenarios, self-extinguishing properties can also be achieved (burning stops quickly after leaving the fire source).
In addition, the base material (organic polysiloxane) of phenyl elastic putty itself has a certain heat resistance. When combined with flame retardants, it can not only maintain structural stability at high temperatures, but also reduce the release of toxic smoke during combustion. This enables it to have elastic buffering functions while meeting the flame retardant safety requirements in multiple fields.
