Kingflex
Explore our high-performance thermal insulation solutions designed for ultra-low and industrial temperature regulation.
The global cryogenic insulation market is experiencing a rapid technological evolution driven by the unprecedented expansion of the Liquefied Natural Gas (LNG) supply chain, clean hydrogen initiatives, and complex petrochemical industrial processing systems. In these environments, processing temperatures plunge below -160°C for LNG and down to -196°C for liquid nitrogen, making conventional insulation systems obsolete.
At cryogenic temperatures, ambient moisture poses a significant threat. A minor failure in the vapor barrier allows moisture to migrate toward the cold surface, forming ice. Because water expands upon freezing, it causes mechanical fracturing of the insulation structure. This compromises thermal efficiency and accelerates Corrosion Under Insulation (CUI) on the underlying piping systems.
Established by the Jinwei Group, which boasts a rich history of over 40 years since its inception in 1979, Kingflex Insulation Co., Ltd. was the pioneer manufacturer of thermal insulation materials north of the Yangtze River. Operating as a professional manufacturing and trading combo, Kingflex integrates green-building materials R&D, production, sales, installation guidance, and dedicated post-sale consulting.
Our state-of-the-art facility is located in Dacheng, China—a hub for green building technology. With 5 automated, high-precision assembly lines, we achieve an annual production capacity of over 600,000 cubic meters. This scale and technical capability make us a designated supplier for the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry.
Why elastomeric systems are replacing rigid materials in cryogenic applications
Traditional systems like cellular glass and rigid foams are prone to cracking under the thermal stress of startup and shutdown cycles. Flexing of pipes due to thermal contraction can damage rigid structures, leaving gaps that invite moisture.
Kingflex Elastomeric Cryogenic Insulation utilizes a modified NBR/PVC matrix that retains its flexibility down to -200°C. This eliminates the need for contraction joints, simplifying installation and reducing maintenance costs.
Our R&D team has engineered a rubber foam matrix that guarantees a closed-cell rate of over 98%. This configuration provides a built-in water vapor barrier, yielding a high moisture resistance factor (μ ≥ 10,000).
