High-performance elastomeric and thermal shielding products optimized for French industrial and energy infrastructures.
Decarbonization, Liquid Hydrogen (H2) and LNG Infrastructure Demands
France is rapidly transforming its energy profile under the "France 2030" investment plan, placing massive emphasis on decarbonization, green hydrogen production, and the modernization of its LNG terminal networks (such as Dunkerque LNG, Montoir-de-Bretagne, and Fos Cavaou). Cryogenic technology is the linchpin of these developments. Transitioning to green hydrogen requires transporting and storing liquids at a challenging -253°C, while LNG handling necessitates absolute containment stability at -162°C.
Managing thermodynamic energy leaks at these critical temperatures demands superior structural and elastomeric insulation systems. Inadequate vapor barrier sealing leads immediately to condensation, severe icing, and localized structural failure of pipes due to thermal stress. Kingflex's closed-cell elastomeric foam configurations are precision-engineered to prevent thermal bridging and eliminate Corrosion Under Insulation (CUI), safeguarding critical French petrochemical, pharmaceutical, and aerospace pipelines.
Critical maritime gateways for imported energy gas storage requiring complex pipe isolation networks.
Ariane launcher propulsion systems needing high-purity, ultra-low temperature component insulation.
A Legacy of Quality, Research & Global Supply Strength
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal and cold insulation products. Kingflex's research development and production department is situated in Dacheng, China, globally recognized as the capital of energy-efficient green-building materials. Guided by a core operational vision of energy saving and emission reduction, we offer complete consultation, R&D, product manufacturing, on-site installation guidance, and dedicated post-sale engineering services.
Established under the parent umbrella of the Jinwei Group, which boasts a rich legacy of more than 40 years since its founding in 1979, Kingflex inherits the expertise of the pioneer thermal insulation manufacturer north of the Yangtze River. Currently, the company runs 5 large automatic assembly lines, generating an annual manufacturing output of over 600,000 cubic meters. Our systems have been vetted and designated for high-stakes projects by major international ministries of energy and chemical industries, with export operations spanning 66 foreign countries.
Decades of building technical expertise and scaling operations globally
Jinwei Group is established, marking the first major thermal insulation manufacturing facility in Northern China.
Expanding product focus from standard thermal insulation to advanced industrial cold insulation systems and rubber foams.
Kingflex brand establishes dedicated export networks, delivering energy-saving solutions to the European Union and Middle East.
Achievement of 600,000 m³ capacity across 5 advanced automatic lines, supplying large-scale LNG terminal insulation worldwide.
Why closed-cell elastomer structures outperform traditional mineral wool in cold preservation systems
Unlike fibrous rock wool which absorbs moisture, Kingflex's NBR/PVC closed-cell structure has an inherent moisture resistance factor (μ ≥ 10,000) acting as a continuous, impenetrable vapor barrier.
Formulated to operate from -200 °C to +105 °C. Elastomeric resilience maintains a tight thermal grip without cracking or collapsing under cryogenic cyclic shocks.
Corrosion Under Insulation (CUI) costs industries millions. By excluding water ingress entirely, our closed-cell rubber sheet guarantees that under-pipe steel surfaces stay bone dry.
In a fluctuating global trade market, Kingflex ensures uninterrupted logistics pipelines. Supported by direct access to raw raw-material chemical sources, high-automation output, and bulk volume transport routes through Tianjin port, we guarantee reliable deliveries to major French hubs. From structural customization to specific sizing configurations, we deliver within predictable windows, keeping energy and construction projects on schedule.
Standards Compliance: Our products are certified under BS 476, CE, REACH, RoHS, UL94, and ASTM standards, meeting rigorous French and European safety, fire-retardant, and environmental health parameters.
Innovating solutions with rigorous testing and technical expertise
Our company's strength lies in our unified workforce. Our team is a tight-knit, talented group with a shared vision of giving consistently first-class service for our clients. Currently, Kingflex employs 8 professional engineers in our R&D Department, 6 professional international sales managers dedicated to smooth contract execution, and 230 skilled manufacturing workers operating our automated pipelines.
The R&D team works closely with testing institutes to refine the chemical composition of our NBR/PVC compounds. This constant testing pushes our rubber foam materials to withstand cryogenic extremes without losing flexibility or experiencing cells cracking. Every batch is traceable back to its production log, ensuring absolute accountability for our industrial clients.

Dimension Profile:
Primary Benefits:
Evenly distributed cell structure with a high closed-cell rate of over 98%. Under testing, it yields a compression resilience of over 80% and possesses self-extinguishing safety properties when exposed to fire.
Dimension Profile:
Primary Benefits:
Manufactured with automated spray-coating technology to ensure even cell thickness. This prevents localized heat transfer, minimizes pipe expansion or contraction stress, and reduces the risk of pipe cracking in harsh cold systems.
