Kingflex
Explore our highly-engineered closed-cell elastomeric rubber foams and specialized low-temperature barriers.
Cryogenic insulation systems represent the pinnacle of industrial thermal barrier technology. Unlike conventional HVAC thermal blankets, materials operating in cryogenic zones—ranging from liquid carbon dioxide (-50 °C) to liquid nitrogen and LNG (-162 °C to -196 °C)—must withstand extreme vapor pressure differentials and mechanical contraction stress.
Without high-performance protection, ambient air humidity immediately migrates toward the cold pipe surface. Upon contact, water vapor condenses, freezes, and expands, leading to structural ice formation. This ice buildup degrades the thermal efficiency, triggers corrosion under insulation (CUI), and can cause catastrophic pipeline fractures. Kingflex's advanced elastomer solutions use a closed-cell matrix (>98% closed-cell rate) to establish a built-in vapor barrier, eliminating the need for complex multi-layered jacket installations.
How we address strict international regulatory frameworks and supply chain requirements for megaprojects.
Navigating global regulatory landscapes requires verified documentation. Our insulation materials comply with BS 476 (Part 6 & 7 Class 0), CE, REACH, RoHS, UL94, and ASTM. We provide engineering assistance, material submittals, and installation guidelines for on-site execution.
Located in Dacheng—China's green building materials hub—our facility leverages integrated raw material access, skilled engineering talent, and efficient deep-water logistics. Our automated production lines deliver consistent quality at competitive prices.
We trace every batch from chemical feedstock to the finished roll or pipe. Each shipment includes certified test reports covering density, cell structure uniformity, fire behavior indexes, and low-temperature flexibility tests.

Our cryogenic and low-temperature systems protect critical infrastructure worldwide.
Used to wrap large-scale cryogenic storage tanks and LNG terminals. The low thermal conductivity maintains sub-zero temperatures, limiting Boil-Off Gas (BOG) generation and optimizing process plant efficiency.
Protects industrial process lines operating at extreme temperatures. The material resists chemical exposure and degradation, providing CUI protection for ammonia, ethylene, and carbon dioxide lines.
Eliminates condensation risk on chilled water lines and central air conditioning systems. The closed-cell material acts as a barrier against humidity, preventing mold growth and moisture damage.
Kingflex Insulation Co., Ltd. operates five automated production lines with an annual output exceeding 600,000 cubic meters. As a designated manufacturing partner for major Chinese ministries (including Energy, Electric Power, and Chemical Industry), we maintain high standards of product consistency.
Our R&D team consists of eight dedicated engineers who focus on optimizing low-temperature polymer formulations. Our research center tests insulation performance under simulated extreme conditions, ensuring long-term reliability in the field.
Inside our factories, research laboratories, and global quality control stations.
We work closely with global engineering, procurement, and construction (EPC) contractors, providing end-to-end design, fabrication, and shipping coordination.
Our international team handles the logistics, ensuring compliance documentation, customs clearance, and safe transit for all structural insulation orders.
Technological shifts driving the future of low-temperature thermal management.
Combining elastomeric rubber with silica aerogels creates thinner, highly flexible insulation composites. This hybrid approach meets tight space constraints while maintaining excellent thermal performance.
Global environmental regulations push manufacturers toward zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP) blowing agents. Our development processes prioritize eco-friendly formulations.
Future cryogenic piping designs integrate structural sensors to monitor temperature drops and early-stage moisture penetration, alerting operators before ice build-up or CUI occurs.
Verified on-site applications of Kingflex insulation systems across major infrastructure sites.
Detailed technical answers addressing common design, selection, and compliance questions.
It is mainly used for HVAC ducts, air conditioning pipes, building thermal insulation, industrial pipeline cold insulation, and sound attenuation. Its flexible closed-cell design makes it ideal for protecting pipelines against temperature changes and ambient moisture ingress.
Yes, our rubber foam insulation products are fire retardant, meeting international safety standards such as BS 476 Part 6 & 7 Class 0, CE, REACH, RoHS, UL94, and ASTM. This ensures suitability for high-occupancy commercial and heavy industrial facilities.
Rubber foam is flexible, closed-cell, and moisture-proof, making it suitable for HVAC and cold insulation down to cryogenic ranges without an additional vapor barrier. Rock wool is high-temperature resistant and fireproof, making it better suited for high-temperature steam lines and structural fire containment.
