Engineered to deliver exceptional thermal resistance and prevent condensation in demanding high-tech applications.
In an era focused on energy optimization and reduced carbon emissions, managing extremely low-temperature fluids—such as Liquefied Natural Gas (LNG at -162°C), Liquid Oxygen (LOX at -183°C), and Liquid Nitrogen (LIN at -196°C)—requires precise thermal engineering. High-performance cryogenic tank insulation systems are critical for maintaining system integrity and operating efficiency.
Without adequate thermal protection, cryogenic storage tanks and pipelines face significant challenges: massive boil-off gas (BOG) losses, severe condensation and ice build-up, and structural stress due to extreme thermal gradients.
Kingflex Insulation Co., Ltd. addresses these challenges by developing advanced closed-cell elastomeric structures tailored for extreme low-temperature applications. By offering low thermal conductivity alongside high water vapor resistance, our solutions provide reliable energy conservation and process safety worldwide.
Understanding the physics of low-temperature insulation helps engineers select the ideal material for their cryogenic operations.
Features a flexible, dense closed-cell structure with integrated vapor barriers. It performs exceptionally well under high vibration and cycling conditions.
A rigid, 100% glass material with zero water vapor permeability. Excellent load-bearing capabilities but susceptible to thermal shock fracturing.
Rigid polyurethane/polyisocyanurate foams that provide strong thermal efficiency, commonly used in pre-insulated pipe-in-pipe systems.
Traditional rigid insulation systems require expansion joints to accommodate thermal movement, which can introduce moisture paths and lead to ice formation. Kingflex’s elastomeric cryogenic system features built-in flexibility that contracts and expands in harmony with cold piping, eliminating the need for complex expansion joints and reducing the risk of corrosion under insulation (CUI).
Kingflex Insulation Co., Ltd. operates as a specialized manufacturing and trading combo, focusing on thermal and cryogenic insulation products. Our R&D and production facilities are based in Dacheng, China—a major national hub for green building materials. As an energy-efficient enterprise, we integrate research, manufacturing, technical consulting, and post-sale support.
We are backed by the Jinwei Group, established in 1979. With over 40 years of experience, the Jinwei Group was the first manufacturer of thermal insulation materials north of the Yangtze River.
Leveraging decades of production knowledge, Kingflex offers comprehensive insulation, cold conservation, and noise reduction solutions for modern civil, marine, and heavy industrial settings.
Our robust manufacturing infrastructure ensures stable supply chains and consistent product quality for global projects.
At Kingflex, our team is central to our success. We bring together dedicated professionals who share a vision of delivering reliable service to our clients.
Our structure includes:
Kingflex products are manufactured to rigorous specifications to meet international safety and environmental codes.
As materials approach cryogenic temperatures, they undergo physical changes. Standard polymers and rubber materials can reach their glass transition temperature ($T_g$), causing them to become brittle and crack under minimal mechanical load.
Kingflex's cryogenic thermal insulation line addresses this by incorporating specialized plasticizers and custom rubber compounds. This modification keeps the elastomer flexible below -40°C, helping the system absorb structural movement without cracking.
Our materials undergo regular testing in our dedicated labs to confirm physical performance: tensile strength, density uniformity, flame spread indexes (UL 94, BS 476 Part 7), and low thermal conductivity under varying ambient temperatures.
Kingflex maintains third-party certifications to support traceabilty and compliance on international project sites:
*Certifications cover BS 476 Fire Rating, CE Compliance, REACH Chemicals Registry, RoHS Directive, UL94 Flammability Testing, and ASTM Thermal Performance Standards.
Kingflex elastomeric cryogenic foam systems are designed for use across diverse industrial and marine sectors.
Used in LNG bunkering stations, storage tank base shells, and transport piping networks. Kingflex helps limit boil-off gas rates, helping operators manage storage pressures and retain gas inventory.
Protects ethylene plants, liquid oxygen systems, and sub-zero process pipes. Its closed-cell structure blocks environmental moisture, reducing condensation risks on cold pipe walls.
Designed for dual-fuel vessel fuel lines. The material provides flexible vibration resistance and stands up to saltwater air without degrading, keeping pipe systems protected.
Our products are sized to support fast installation on standard ASTM and DIN piping arrays:

In large-scale industrial construction, lead times and material consistency are critical project factors. Producing out of Dacheng, China, Kingflex operates within an established industrial ecosystem for insulation materials. This provides direct access to primary raw components and a trained technical workforce.
Our five automated production lines deliver a combined capacity of over 600,000 cubic meters annually. This scale allows us to handle large-volume orders and maintain stable delivery timelines, even during periods of high market demand.
Over the past 16 years, we have exported to 66 countries. Our logistics team handles international port clearances and container packing, helping ensure materials arrive at project sites in proper condition.
We work closely with procurement teams and insulation engineers to verify that our products meet their design specifications.
Our quality management system tracks materials from raw inputs to shipment. Every production run is logged with density profiles, water absorption ratios, and physical measurements for transparency.
