Explore our core engineered elastomeric and acoustic insulation systems optimized for energy efficiency
In an era heavily focused on energy conservation, the demand for high-performance thermal insulation has reached unprecedented levels. Modern industrial processes, commercial HVAC networks, and cryogenic logistics require structural engineering materials that minimize thermal bridging, prevent moisture condensation, and optimize environmental metrics.
NBR/PVC based elastomeric closed-cell insulation has emerged as the global standard for low and medium-temperature applications. Because it features a high density of microscopic closed cells, it blocks heat transfer and offers robust resistance to moisture vapor.
Established by the Jinwei Group, which holds a distinguished history spanning more than 40 years, Kingflex Insulation Co., Ltd. has developed into a premier manufacturing and trading combo for thermal insulation systems. Kingflex's roots trace back to 1979, establishing itself as the first manufacturer of thermal insulation materials north of the Yangtze River.
Our dedicated research, development, and advanced manufacturing complexes are strategically located in Dacheng, China—widely recognized as the capital of green-building materials. Today, we operate five fully automated assembly lines. Our production has earned designated supplier status from the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry in China.
How Dacheng's green-building ecosystem translates into high value for global buyers
Procuring directly from China allows global buyers to benefit from unmatched manufacturing scales. By grouping raw chemical sourcing, custom mold fabrication, extrusion, and testing in Dacheng, we eliminate logistical bottlenecks.
This operational model delivers major benefits for international purchasers:
Precise engineering dimensions designed to fit global structural and industrial requirements
Uniform foaming ensures consistent thermal performance. High compression resilience (>80%) makes it highly resistant to physical deformation on construction sites.
Perfect for central air conditioning air ducts, large industrial steam pipes, storage tanks, and building walls/roofs requiring acoustic dampening and thermal regulation.
Our pipe spraying application process ensures an even coat, making installation easy and significantly reducing the risk of pipe freezing or cracking in cold climates.
Chilled water loops, domestic hot/cold water supply lines, refrigeration pipes, condensate pipelines, and solar thermal loops.
For demanding environments, we supply specialized solutions designed for ultra-low and cryogenic systems operating down to -200 °C. These materials prevent condensation and thermal shock in LNG processing facilities and liquefied gas pipelines.
Active research, development, and inspection processes verified by international standards bodies
Continuous thermal conductivity and flammability testing inside our advanced DACheng facility.
Precise weighing and blending systems regulate density, flexibility, and flame retardancy.
Strict quality inspections check thickness consistency, inner diameters, and closed-cell properties.
Demonstrating compliance with global fire safety and environmental regulations
Demonstrated customer satisfaction and transparent engineering support across borders
