High-performance fire-resistant
Silicone sealants have become a key standard configuration for high-rise buildings, industrial plants, rail transit, and aerospace facilities in 2026, as global safety production and building fire protection standards continue to be upgraded. With the continuous improvement of public safety requirements, traditional ordinary sealants can no longer meet the fire protection and sealing needs of high-risk scenarios, and fire-resistant silicone sealants with flame retardant, smoke suppression, and high-temperature resistance functions have achieved rapid market penetration.
Ordinary silicone sealants will soften, melt, and burn rapidly when encountering high temperature and open fire, losing sealing and protective functions, and easily causing the spread of fire and smoke. In contrast, the new generation of fire-resistant silicone sealants launched in 2026 adopts halogen-free flame retardant formulas and high-temperature resistant molecular materials. When exposed to high temperature, the colloid will rapidly carbonize to form a dense and rigid fireproof protective layer, which can effectively isolate flames, high-temperature heat flow, and smoke diffusion. Test data shows that the product can withstand high temperatures above 1200℃ for a long time, and the fire resistance limit can reach more than 3 hours, fully meeting the highest fire protection standards of modern buildings and industrial facilities.
At present, fire-resistant silicone sealants are widely used in key safety parts such as building wall gaps, cable through-wall holes, pipeline penetration parts, and fire door and window gaps. In the field of rail transit, they are applied to the fireproof sealing of subway tunnels, high-speed train carriages, and station facilities. In the industrial field, they are used for fireproof and explosion-proof sealing of chemical plants, power plants, and energy storage equipment. In the aerospace field, high-precision fire-resistant silicone sealants ensure the operational safety of aircraft and aerospace equipment in extreme high-temperature environments.
Industry market data shows that the market scale of fire-resistant silicone sealants has maintained a year-on-year growth of more than 20% in 2026, becoming the fastest-growing segmented product in the construction and industrial sealant market. With the continuous tightening of global fire safety codes and the increasing investment in public safety infrastructure, the market demand for fire-resistant silicone sealants will continue to rise. Industry experts predict that fire-resistant functional sealants will become the mainstream upgraded product of the construction sealant industry in the next three years, and the market share will continue to expand rapidly.
