Explore our top-tier flexible elastomeric insulation solutions engineered to withstand critical industrial temperatures.
In modern HVAC engineering, petrochemical processing, and cryogenic distribution systems, thermal loss equals financial leakage and structural vulnerability. As global industrial processes scale, the demand for flexible high-temperature insulation that functions flawlessly between extremes has skyrocketed.
Unlike rigid insulation materials like fiberglass or cellular glass, which are prone to cracking, water vapor intrusion, and structural failure under mechanical stress, elastomeric NBR/PVC closed-cell foam technology provides dynamic energy saving, extreme thermal stability, and long-term acoustic isolation.
By utilizing a highly developed closed-cell microscopic structure, this insulation prevents water molecules from migrating through the material. In cryogenic pipelines, moisture ingress leads to rapid ice formation, expanding and destroying the insulation barrier. A high water-vapor resistance factor (μ ≥ 10,000) acts as an integrated vapor retarder, ensuring that the initial thermal conductivity (λ ≤ 0.035 W/(m·K) at 0°C) remains stable over years of constant operation.
At the heart of Kingflex's market leadership is our relentless pursuit of material innovation. Our dedicated Research & Development department, powered by 8 professional materials engineers, operates advanced simulation and raw-material synthesis facilities. We focus on refining the elastomer cross-linking density, optimizing thermal insulation performance, and maximizing fire retardancy under strict international safety standards.
Our formulations incorporate specialized organic fire retardants, permitting our materials to achieve BS 476 Part 6 & 7 Class 0 and Class 1 certifications, as well as UL 94 V-0 ratings. This ensures that in the event of an industrial fire, the material does not feed the flames, creates minimal smoke toxicity, and is self-extinguishing immediately when the flame source is removed.
Leveraging the raw material cluster of Dacheng to deliver unmatched cost efficiency and technological compliance.
Kingflex production center sits in Dacheng, the globally recognized capital of green building materials in China. Our geographical integration ensures immediate access to primary polymer resins, foaming agents, and process stabilizers. This vertical material proximity drastically minimizes raw material transport costs and guarantees production continuity.
With 5 large automatic assembly lines, our factories achieve consistent cell-geometry matrix forming. Automation reduces human-error variance to less than 0.5%, optimizing raw material density from 40 to 55 kg/m³. We meet large volume infrastructure project demands rapidly without quality decay.
Every product batch undergoes continuous destructive testing, heat-aging tests, and water permeability audits. Our products strictly comply with REACH and RoHS standards, ensuring they are free from heavy metals, PBDEs, and PBBs. Our ISO certifications prove our status as an authoritative market player.

It is mainly utilized in heavy-duty HVAC systems, air conditioning distribution lines, building acoustics, commercial thermal barriers, and industrial/petrochemical pipe setups. By establishing a moisture-impenetrable barrier, it safeguards cold piping networks from energy loss and environmental stress.
Absolutely. Our elastomeric compounds are synthesized using tailored fire-retarding additives. Kingflex materials meet strict BS 476 Part 6 & 7 Class 0/Class 1, UL94, and international marine fire safety standards, providing optimal self-extinguishing characteristics.
Rubber foam is a highly flexible, closed-cell elastomer with built-in moisture-vapor protection, making it ideal for systems prone to condensation like HVAC systems and cryogenic pipes. Rock wool is a fibrous mineral structure that excels at extremely high temperatures (up to 1000°C) and acts as an open-cell fire wall.
