Premium grade closed-cell rubber foam, mineral fibers, and high-tensile thermal barriers direct from factory lines.
Modern building codes have transitioned from basic thermal retention to integrated fire safety and smoke containment. In industrial plants, commercial high-rises, and marine applications, traditional insulation systems can worsen fire scenarios by releasing toxic gases and dense smoke. Kingflex Insulation Co., Ltd. specializes in closed-cell elastomeric rubber foam engineered to mitigate these hazards.
Our smoke-retardant thermal systems are designed to limit toxic emissions during extreme thermal exposures. By sealing individual cells with low-density nitrogen gas, we prevent moisture ingress—which causes under-insulation corrosion (CUI)—while offering certified flame resistance that complies with international building and safety standards.
The mechanical performance of elastomeric smoke insulation hinges on two primary criteria: thermal conductivity and fire propagation control. Below are the design specifications for our flagship sheet rolls and pipe sections.

Features a compression resilience rating above 80%. This prevents cell deformation during structural shifting, keeping thermal insulation and smoke barrier performance intact over decades of heavy service.
Manufactured with fire-retardant additives. If exposed to fire, our materials self-extinguish quickly without generating the heavy, toxic smoke typical of standard polyurethane foams.
Boasting a closed-cell rate of over 98%, this moisture barrier system prevents water penetration. This stops fungal growth and eliminates moisture accumulation, keeping thermal conductivity low over time.
Industrialization and safety policies worldwide are driving the demand for advanced thermal barriers. Building regulations—such as Europe’s EN 13501-1, China’s GB 8624, and the American ASTM E84—require materials that release very little smoke and resist flames.
Contractors and engineers need to choose materials that help prevent the spread of smoke in high-density facilities like data centers, airports, and hospitals. Our elastomeric systems help projects meet these strict criteria. They deliver top-tier fire safety while helping to lower HVAC system energy costs.
Due to its high flexibility, low thermal conductivity, and strong fire/smoke protection, Kingflex insulation is widely used in multiple demanding industries:
Applied to supply and return air ducting networks to prevent condensation, minimize radiative energy losses, and stop smoke from moving through ventilation systems in a fire.
Controls high temperature changes, keeps fluids flowing at consistent temperatures, and protects plant personnel from burns. The system also prevents corrosion under insulation (CUI) on pipes.
Designed for LNG processing terminals, petrochemical facilities, and cold storage storage facilities. This material prevents ice buildup and helps maintain ultra-low temperatures.
Operating out of Dacheng, China—the hub of eco-friendly building materials—our production base features 5 fully automated extrusion lines. With an annual capacity of over 600,000 cubic meters, Kingflex maintains reliable, continuous supply chains for large-scale infrastructure projects worldwide.
We are a designated supplier for the Ministry of Energy, Ministry of Electric Power, and Ministry of Chemical Industry in China. Our integrated quality management system ensures every production batch is fully traceable from raw NBR monomers to the finished, boxed rolls or pipes.
As standard environmental regulations tighten, the industry is moving away from halogenated fire retardants. Halogenated additives can produce toxic halogen acid gases when exposed to fire. Kingflex is leading this shift by developing halogen-free elastomeric insulation rolls and pipes.
By using non-halogenated minerals and nitrogen-based carbonizing agents, our materials achieve high fire safety without releasing corrosive acid vapors during combustion.
We are researching renewable plant-derived polymers to replace petroleum-based nitrile rubbers. This will lower the carbon footprint of our manufacturing process while maintaining high flexibility and durability.
We are developing smart insulation systems that embed moisture sensors directly into the closed-cell matrix. These sensors monitor pipelines in real time, alerting maintenance teams to potential issues before Corrosion Under Insulation (CUI) can occur.
Kingflex materials undergo rigorous third-party testing to meet international regulatory standards. Our products carry approvals from key certification bodies, ensuring compliance and peace of mind for projects worldwide.
