Kingflex
Premium elastomeric thermal materials engineered to prevent freezing condensation and minimize energy loss in extreme sub-zero temperatures.
A comprehensive overview of thermal performance standards, energy policy, and microcellular solutions in Northern Eurasian environments.
Insulation solutions implemented in the Russian Federation, extending from urban centers like Moscow and Saint Petersburg to the rugged industrial expanses of Siberia and the Far East, encounter unique climatic challenges. Conventional insulation materials face severe thermal degradation when subjected to repetitive freeze-thaw cycles. Moisture ingress is the primary cause of insulation failure. When vapor enters an open-cell structure and freezes, it expands, causing irreversible structural breakdown and a significant spike in thermal conductivity.
Microcellular Elastomeric Technology (Closed-Cell NBR/PVC) addresses this vulnerability. With a closed-cell ratio exceeding 98%, our rubber foam sheets prevent vapor diffusion, maintaining thermal integrity even under high relative humidity and significant temperature gradients.
Thermal installations in Russia must comply with strict national regulatory standards. Standard building codes demand certified fire behavior under GOST 30244-94. Our elastomeric foam sheet rolls are designed to achieve the G1 (low flammability) or G2 flammability ratings, self-extinguishing without generating burning droplets. Furthermore, the material meets the requirements of Russian sanitary regulations, ensuring zero dust or fiber release—crucial for installation in public facilities, clinical complexes, and food processing plants.

Eliminates surface moisture formation on chilled pipes operating in industrial manufacturing and public buildings during humid summer cycles, preventing corrosion under insulation (CUI).
The microcellular structure absorbs structural vibrations and airborne noise in heavy industrial utility rooms, lowering decibel levels by up to 28 dB(A) at 1000Hz.
Enhanced polymer formulation containing active ozone inhibitors to prevent cracking and degradation caused by atmospheric UV exposure in exposed regional environments.
A multi-decade legacy in advanced polymer foaming, serving global markets from China's green-building material capital.
Kingflex Insulation Co., Ltd. operates as a professional manufacturing and trading combo for high-end thermal insulation products. Our core research, development, and primary manufacturing departments are situated in Dacheng, China—a hub for green-building material production. As an energy-saving, environmentally conscious enterprise, Kingflex integrates advanced R&D, automated manufacturing, and technical sales support.
Established by the Jinwei Group, which has a legacy spanning over 40 years since its inception in 1979, Kingflex builds upon a strong foundation. Jinwei Group was a pioneer in thermal insulation materials manufacturing north of the Yangtze River. Today, Kingflex leverages this expertise, providing global industries with reliable insulation solutions.
We operate 5 large automatic assembly lines, generating an annual production capacity exceeding 600,000 cubic meters. Kingflex is recognized as a qualified manufacturer for major power and chemical entities globally. Our supply chain ensures timely, bulk deliveries to major hubs in Russia, including Vladivostok, Novosibirsk, and Moscow, via optimized rail networks and maritime shipping routes.
A strong technical foundation is essential for designing high-performance products. Our team of eight professional engineers in our R&D Department continuously refines the chemical composition of NBR/PVC elastomeric formulations, optimizing flexibility, density, and thermal resistance.
We offer specialized assistance to global engineering contractors through a dedicated international sales team and 230 technicians. Kingflex provides comprehensive support, including initial design calculations, assistance with customs clearance, and technical installation guidance on-site.

Why international EPC engineering firms choose Kingflex for complex projects in demanding climates.
Every production batch is assigned a unique tracking identifier. Kingflex maintains detailed records of raw materials, chemical formulations, and test results, ensuring compliance with strict industrial engineering standards.
Delivering insulation rolls to remote Russian mining regions or municipal utilities requires durable packaging. Our product rolls are packed in heavy-duty polyethylene sleeves with protective corrugated side caps. This prevents mechanical damage and moisture exposure during transit, ensuring the material arrives ready for installation.
Depending on the climatic zone (e.g., Central Russia vs. Arctic circles), standard thicknesses may not suffice. Kingflex provides customized thicknesses from 6mm up to 50mm, along with high-density outer protective coatings (like aluminum foil or reinforced fabric layers) to resist mechanical wear and weathering.
