2. The flame-retardant performance of rubber and plastic foams is excellent. These foams contain a substantial amount of flame-retardant and smoke-suppressing materials. When rubber and plastic foams burn, the smoke concentration is very low, and they won't melt or drop burning droplets upon contact with fire. Additionally, they possess an auto-extinguishing feature.

      3. The rubber-foam sponge itself has excellent softness, making installation extremely easy and convenient. Due to its smooth and flat surface like rubber, and its many superior properties, additional vapor barriers and protective layers are not needed during installation. This not only simplifies the installation process but also enhances the aesthetic and flat appearance.

      4. Rubber and plastic foams typically have high elasticity, so they usually significantly reduce resonance and vibration in hot water or chilled water pipelines during operation.

      5. Rubber and plastic foams are safe and environmentally friendly, posing no health risks to humans or skin irritation. Additionally, they effectively prevent the growth of mold in pipes, protect against gnawing by rats or pests, and exhibit excellent resistance to both acids and alkalis.
