Keywords: Silicone firestop mud, GB 23864-2026, fire safety, industrial insulation, Hongye Silicone Summary: Demand for silicone firestop mud surged 40% YoY as GB 23864-2026 fire safety standard implementation nears; high-purity silicone formulations dominate petrochemical and power applications. May 11 market data shows rising demand for non-solidifying silicone firestop mud, driven by the upcoming implementation of GB 23864-2026 (firestop material standard). High-purity 100% silicone formulations, stable from -50°C to 220°C and lifelong non-hardening, are preferred for petrochemical, power, and rail transit applications. These products offer integrated fire resistance, moisture proofing, corrosion protection, and vibration damping, replacing traditional rubber-based firestops. Hongye Silicone is developing high-performance silicone firestop mud, targeting ISO and CCCF certification by late 2026.
