Flame retardant principle of flame retardant silicone rubber
2024-10-21
The reason why flame retardant silicone rubber has flame retardant properties is that a silicone rubber flame retardant is added to the silicone rubber raw material. After adding this flame retardant, the silicone rubber will release water when it is decomposed by heat and absorb a large amount of latent heat, thereby reducing the actual temperature of the flame on the surface of the material. At the same time, the polymer will degrade into combustible low molecules, but the generation rate of combustible low molecules will be reduced, and a large amount of water vapor will be released, which will reduce the concentration of oxygen and combustible gas near the surface of the polymer, making it difficult for the surface of the silicone rubber to continue to burn.
