Kingflex
Premium thermal, cryogenic, and acoustic insulation solutions manufactured on automated production lines.
Kingflex Insulation Co., Ltd. is a world-class manufacturing and trading integration combo specializing in advanced thermal, cryogenic, and noise-reduction insulation systems.
Strategically situated in Dacheng, China—the globally recognized capital of green building materials—our R&D and production facilities are built to drive ecological energy savings. Our core philosophy is centered on carbon footprints and energy efficiency. We offer a comprehensive suite of customized solutions that include technical consulting, materials development, precision production, global logistics, installation guidance, and lifetime after-sales support.
Backed by the industrial heritage of the Jinwei Group (established in 1979, the first manufacturer of thermal insulation materials north of the Yangtze River with over 40 years of pioneering research), Kingflex stands as an industry authority setting benchmarks in energy conservation.
Why the "1000 Sq Ft" benchmark represents a critical scale in modern building designs, industrial manufacturing, and modular process engineering.
In industrial design, 1,000 square feet (approx. 93 m²) serves as a standardized sizing module for specialized workspaces. These include server cold-aisle containment pods, precision medical cleanrooms, mobile containerized processing units, and high-efficiency HVAC plant rooms. Achieving perfect thermal equilibrium within these spaces demands closed-cell elastomeric technology with minimized thermal bridging.
For multi-facility operators, managing thermal losses over standardized 1,000 sq ft building increments is crucial to controlling operating expenses (OPEX). Selecting premium NBR/PVC elastomeric rubber foam or fire-resistant rock wool insulation ensures long-term thermal resistance (R-value stability) and prevents condensation-driven corrosion under insulation (CUI).
Industrial units containing critical machinery or electronic devices require strict safety certifications. Kingflex systems conform to standard Class 0 and Class 1 flame retardancy ratings (BS 476, UL94, and ASTM E84). This provides high smoke containment and flame suppression capability, protecting valuable equipment and infrastructure.
Managing large-scale commercial real estate, chemical plants, and data centers requires highly reliable supply chains. Kingflex provides distinct structural advantages that ensure consistent performance:
Demonstrating institutional capacity and international reliability over decades of operation.
Our insulation materials are optimized to perform in challenging environments. Whether managing sub-zero cryogenic systems or high-temperature steam lines, the technical configurations below deliver long-term thermal efficiency.
In central air-conditioning applications, Kingflex sheet rolls prevent condensation on cold surfaces and limit energy transfer. Closed-cell rubber foam helps maintain system efficiency by reducing cooling losses over long duct runs.
Key Specifications:Ultra-low temperature storage, LNG transport, and chemical process piping require specialized moisture resistance and low-temperature flexibility to prevent cracking and system failures.
Key Specifications:At Kingflex, we believe our people are the foundation of our success. Our R&D department houses 8 professional engineers, supported by 6 international sales consultants and 230 manufacturing specialists.
This combined expertise enables us to support custom project dimensions, provide comprehensive technical documentation, and coordinate complex shipping logistics for worldwide delivery.

Kingflex elastomer insulation rolls are formulated to offer long-term thermal resistance and reliable moisture protection for broad surface area installations.
Manufactured to match standard industrial copper and steel pipe sizes, this system provides insulation for cold or hot process piping, reducing condensation risks.
Managing storage, transport protection, and loading for global shipments.
Technical guidance, specification parameters, and ordering information for Kingflex products.
Elastomeric rubber foam insulation is used primarily to prevent condensation, control heat transfer, and damp acoustic vibration. Common applications include HVAC ductwork, commercial air conditioning lines, cold water pipes, process piping, cold storage rooms, and acoustic treatment for machinery spaces.
Yes. Kingflex rubber foam is manufactured to meet Class 0 and Class 1 building codes, including BS 476 Part 6/7, UL94, and ASTM E84 test criteria. It features self-extinguishing behavior, does not drip, and produces low smoke density in fire scenarios.
Elastomeric rubber foam is a flexible, closed-cell material that is highly resistant to moisture vapor transmission, making it suitable for cold systems and HVAC. Rock wool is an open-fiber mineral insulation designed for high-temperature applications, industrial piping, and fire stopping where temperature limits exceed 100°C.
Yes, we provide OEM and ODM manufacturing services to meet specific project dimensions, thickness targets (from 6mm up to 50mm), skin variants (such as aluminum foil facing), and pre-cut geometries.
Kingflex materials carry international compliance certifications, including BS 476, CE, REACH, RoHS, UL94, and ASTM. Our manufacturing operations are certified under ISO 9001 and ISO 14001 quality management structures.
Yes. Every production run has associated batch codes and QC markings. This allows tracking from raw material intake through processing, shipping, and installation, supporting international construction auditing systems.
Our standard production thickness for elastomeric sheets and rolls ranges from 6mm to 50mm. Thicker specifications can be manufactured upon request or achieved by layering materials during installation.
When installed according to specifications, Kingflex rubber foam insulation typically provides a service life of 10 to 15 years in standard indoor HVAC environments, maintaining its structural integrity and thermal resistance.
Aligning manufacturing capabilities with global environmental and energy-efficiency standards.
Kingflex operates 5 automated assembly lines with a capacity of over 600,000 cubic meters annually. Our materials are used across the construction, energy, chemical, and aerospace industries, with exports reaching more than 66 countries.
