Kingflex
South Korea stands as a global epicentre for high-tech manufacturing, heavy chemical processing, and maritime LNG engineering. Mega projects concentrated in industrial hubs like Ulsan, Geoje, Yeosu, and Daesan demand exceptionally robust cold insulation systems. Operating at temperatures down to -200 °C, applications such as liquid gas transport, petrochemical cracking lines, and semiconductor clean room chilling systems cannot afford insulation degradation or moisture intrusion.
Condensation is the primary catalyst for system failure and Corrosion Under Insulation (CUI). Our range of closed-cell elastomeric rubber foam insulation products solves this by offering a zero-permeability barrier combined with extremely low thermal conductivity (λ ≤ 0.035 W/m·K at 0 °C).
We supply South Korean contractors, EPC companies, and industrial buyers with cost-efficient, high-volume production capabilities directly from the capital of green-building materials in Dacheng, China. Our technical department supports custom material specifications that align with Korean Fire Safety Standards and international testing norms like ASTM, BS476, and CE.

Our core research, development, and massive manufacturing complex is situated in Dacheng, China—historically recognized as the capital of green-building materials.
Established by the prestigious Jinwei Group, which has a legacy spanning more than 40 years (founded in 1979), Kingflex inherits the expertise of the first thermal insulation manufacturer north of the Yangtze River. Over decades, we have evolved from serving regional thermal networks to engineering advanced elastomeric compounds for modern cryogenic storage systems globally.
Annual Capacity: 5 automatic assembly lines, producing over 600,000 cubic meters annually. This massive output secures our position as a designated partner for global petrochemical projects and heavy industrial builds.
Our R&D team consists of 8 expert chemical engineers who constantly refine NBR/PVC elastomeric formulations to meet the stringent fire-safety, density, and thermal conductivity regulations of international code authorities.
We ensure that every batch of insulation sent to South Korea meets structural safety and environmental compliance standards.
Fully compliant with BS 476 (Class 0 / Class 1), UL94, and ASTM E84 requirements. Self-extinguishing material structure ensures minimal smoke propagation in critical pipeline runs.
ROHS and REACH certified. Completely free of CFCs, HCFCs, and fibers, which guarantees zero off-gassing inside sensitive electronics or semiconductor assembly spaces.
Strict ISO 9001/14001 process control. Every package is batch-coded, providing full traceability from raw materials to chemical foaming lines.

Chilled water loops in clean rooms demand vapor-tight thermal insulation to avoid condensation leaks that could destroy wafer batches. Our dust-free NBR foam is perfect for electronic facility installations.
Shipbuilding yards in Ulsan and Geoje trust closed-cell elastomeric rubber because of its light weight, structural flexibility, and resistance to saltwater environments when compared to heavy glass wool or aerogels.
Petrochemical installations in Yeosu require rapid thermal conservation at extremely low operational thresholds. Kingflex pipes provide persistent, long-term k-value stability.
We invest deeply in product testing. Check out our operational R&D facilities, advanced foaming test laboratories, and warehouse quality control systems.
We build long-term trust with worldwide procurement managers. Our teams communicate transparently, providing structural documentation, testing videos, and rapid order dispatch updates.

Kingflex products have successfully replaced high-cost local materials in major engineering, procurement, and construction (EPC) projects throughout Asia. See our structural projects below:
Challenge: An engineering team required highly flexible closed-cell material to insulate complex piping headers handling boiled-off LNG gas (-163 °C) inside a container vessel's machinery deck.
Solution: We supplied 25mm thickness KINGFLEX -200 °C grade sheets. The high flexibility of our NBR structure allowed simple wrapping on sharp elbows, reducing installation hours by 35% compared to glass wool casings.
Challenge: A major technology fabrication facility experienced heavy condensation dripping from its secondary chiller loop under high ambient summer humidity.
Solution: Our factory supplied pre-cut NBR/PVC elastomeric tubing with an integrated moisture vapor barrier (μ ≥ 10,000). Condensation issues were resolved, ensuring the facility met ISO Class 4 cleanroom cleanliness levels.
Addressing critical engineering inquiries concerning elastomeric foam implementation in cryogenic and low-temperature settings.
