Inquire DetailsAs a global tech node, Seoul and the surrounding Gyeonggi-Incheon metropolitan region demand cutting-edge engineering standards. High-density infrastructure requires highly reliable thermal barriers. In Seoul, cryogenic systems are no longer limited to heavy chemical plants; they drive the capital's high-tech infrastructure, including liquid nitrogen pipelines at major semiconductor research facilities in Gangnam and Pangyo, cold-chain logistical terminals in Incheon, and LNG fuel storage centers powering public utilities.
Operating systems at temperatures as low as -200°C requires advanced materials to prevent moisture infiltration and corrosion under insulation (CUI). Traditional insulation materials often fail due to joint thermal contraction and ice-crystal formation within porous fibers. Our closed-cell rubber foam provides a continuous vapor barrier, maintaining design thermal conductivity ($\lambda$) over decades of operation.
How our advanced manufacturing lines in Dacheng, China, translate to quality and efficiency benefits for South Korean engineering projects.
Operating 5 fully automated assembly lines in Dacheng, China, we produce over 600,000 cubic meters of high-density thermal insulation annually. This scale stabilizes material costs and ensures consistent product density ($40\text{–}55\text{ kg/m}^3$) and cell structures.
Dacheng's proximity to Tianjin Port allows us to complete container loading and dispatch within 24 hours of production. Ocean transit to Incheon Port takes under 48 hours, enabling short lead times for high-volume urban construction projects in Seoul.
Our R&D department enforces international standards compliance. We supply materials that meet CE, REACH, RoHS, UL94, and ASTM requirements, ensuring ready integration into South Korean chemical and mechanical system specs.

Established by the Jinwei Group, which has a manufacturing history extending back to 1979, Kingflex Insulation Co., Ltd. stands as an established enterprise in green-building and industrial thermal preservation materials. Over four decades, we have committed to continuous research and development, transitioning from regional building-materials production to high-tech cryogenic insulation export across 66 countries.
Our core operating team features 8 full-time R&D engineers, 6 international customer support representatives, and a workforce of 230 technicians at our automated Dacheng facility. We supply integrated engineering designs rather than just manufacturing bulk materials.
The first manufacturer of thermal insulation materials north of the Yangtze River, paving the way for advanced modern production.
Our experienced production team handles precision extrusion, thermal molding, and quality control.
Constantly optimizing density structures, thermal coefficients, and anti-aging agents for sub-zero performance.
Our cryogenic and HVAC insulation materials undergo external testing and verification to comply with worldwide regulatory frameworks.
Matching our elastomer sheet rolls and tubing profiles to Seoul's urban development and climate control challenges.
The Seoul Metropolitan Government continues to optimize energy distribution through district heating and large-scale central cooling plants. Our NBR/PVC elastomeric foam is designed to wrap large chillers, expansion loops, and distribution mains. Its closed-cell design resists condensation in the city's humid summer months.
Seoul's tech corridors depend on the distribution of ultra-high purity process gases. Nitrogen, helium, and argon systems require reliable cold retention down to sub-zero range to prevent thermal expansion and pipe fatigue. Our specialized ultra-low temperature insulation limits ambient heat transfer into these process lines.
Distributing fresh goods and biological materials across the metropolitan area requires a stable supply chain. Our elastomeric tubes prevent line freeze-up and condensation build-up in warehouse compressor lines and transit vehicles.
Quality assurance starts in the factory. We employ automated processes and regular testing to verify performance before shipping to Seoul.
Our thermal insulation systems are installed in major manufacturing plants, commercial centers, and municipal piping projects worldwide.
