When burning, it can form a protective layer to isolate oxygen and prevent the spread of fire. Diatomaceous earth can reduce the flame retardancy of the structure. The flame retardant polymer layer 9 uses phosphate flame retardant, which has the characteristics of low toxicity and low smoke, thus improving the overall environmental protection.
