Kingflex
High-performance closed-cell NBR/PVC elastomeric insulation materials designed for supreme thermal efficiency and condensation protection.
Modern air conditioning and variable refrigerant flow (VRF) systems operate under fluctuating environmental conditions, making thermal management and condensation prevention key engineering priorities. Uninsulated or poorly insulated pipelines lead to energy leakage, systemic inefficiencies, and architectural moisture damage. Kingflex elastomeric rubber foam insulation is engineered to address these operational failures using a highly precise, closed-cell micro-cellular formulation.
By compounding high-grade Nitrile-Butadiene Rubber (NBR) and Polyvinyl Chloride (PVC), Kingflex achieves an extremely low thermal conductivity ($\lambda \leq 0.034$ W/m·K at 0°C). The closed-cell rate exceeding 98% functions as a continuous thermodynamic barrier. The dense matrix retains static air pockets, which slows down heat transfer processes. Additionally, the material features an exceptional water vapor diffusion resistance factor ($\mu \geq 10,000$), ensuring the thermal barrier remains dry and effective throughout the system's life cycle.
Why Condensation Control Matters: When warm, humid air contacts cold refrigerant pipes, condensation forms instantly. This moisture damages ceilings, fosters mold growth, and causes corrosion under insulation (CUI). Kingflex's closed-cell configuration prevents moisture from migrating through the insulation, keeping the system efficient and clean.

Dedicated R&D Engineers
Kingflex Insulation Co., Ltd. is a leading manufacturer and exporter specializing in high-performance thermal insulation solutions. Headquartered in Dacheng, China—a hub for green building materials—our production and research facilities prioritize energy efficiency and environmental protection. We manage the entire lifecycle of our insulation solutions, from initial testing and design to production, installation support, and after-sales service.
Established as part of the Jinwei Group, which has a legacy dating back to 1979, Kingflex is backed by over four decades of thermal insulation expertise. As the first insulation material manufacturer north of the Yangtze River, the Jinwei Group laid the foundation for our technical standards. Today, Kingflex has 230 production specialists and 6 dedicated international trade personnel, exporting to over 66 countries across North America, Europe, Asia, and the Middle East.
Our Research and Development department is staffed by eight expert thermal engineering specialists. We continuously refine our elastomer mixtures to improve flame resistance, smoke density control, and structural stability. This R&D focus allows Kingflex to manufacture products that satisfy strict global certifications while maintaining standard thermal efficiency.
How our automated facility in Dacheng delivers consistent product quality and reliable supply chains to global procurement agents.
Kingflex operates 5 large-scale automated assembly lines. Our production processes feature closed-loop monitoring systems that control compounding, extrusion, foaming, and cooling stages. This automation maintains uniform cell distribution and consistent density across all batches.
With an annual capacity of over 600,000 cubic meters, Kingflex handles high-volume orders for large commercial developments and infrastructure projects. We maintain raw material safety buffers to mitigate global supply chain fluctuations.
Our facility in Dacheng is close to major domestic raw material suppliers and global transport ports like Tianjin. This strategic location lowers inland freight costs and ensures quick shipping turnarounds for our international clients.
Our production management complies with environmental guidelines and industrial standards set by the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry. This compliance guarantees that our products satisfy the structural and environmental needs of major HVAC installations.
Detailed physical dimensions and performance ratings for Kingflex insulation systems.
Primary Applications: Large-scale commercial ductwork, acoustic wall damping, building envelopes, high-capacity chilled water storage tanks, and sound insulation in engine rooms.
Primary Applications: VRF/VRV refrigerant lines, split AC copper tubing, hot water loop plumbing, cold chain transport piping, and industrial chemical process systems.
Engineered thermal performance across complex commercial, industrial, and maritime applications.
Kingflex insulation sheets protect large distribution ducts in airports, shopping malls, and office high-rises from thermal loss and condensation. The soundproofing structure also dampens noise transmission from air handling equipment.
Data centers require strict temperature controls to avoid server failure. Kingflex products insulate chilled water supply lines, maintaining constant temperatures and eliminating the risk of water leaks from condensation near electrical systems.
Specifically designed for low-temperature industrial applications, our specialty elastomeric line maintains flexibility and performance down to cryogenic temperatures, preventing crack formation under thermal shock.
Pioneering sustainable and smart insulation technologies for green-building global targets.
In line with international climate agreements, Kingflex is researching bio-based raw materials to replace petroleum-based polymer chains. Our goal is to reduce the carbon footprint of NBR/PVC production without compromising the material's thermal properties or fire-retardant performance.
Our upcoming product line will integrate silica aerogel composites into the elastomeric matrix. This micro-structural refinement aims to lower thermal conductivity to $\lambda \leq 0.029$ W/m·K, allowing for thinner insulation profiles in space-constrained installations.
Meeting rigorous international fire and material safety standards for building and industrial installations.
High-specification projects demand tested compliance with regional fire safety and chemical emission regulations. Kingflex products undergo regular testing to satisfy the requirements of international certification bodies, ensuring compliance for projects in Europe, North America, the Middle East, and Asia.
Our fire-retardant elastomeric formulations meet Class 0 and Class 1 designations under British Standard BS 476 (Parts 6 & 7). They also satisfy European CE EN 14304 regulations for factory-made flexible elastomeric foam products and comply with RoHS, REACH, UL94, and ASTM testing parameters, verifying low smoke toxicity and zero ozone-depleting potential.
Simplifying sourcing for EPC contractors, wholesale suppliers, and HVAC OEMs.
We configure custom densities, wall thicknesses, dimensions, and branded packaging for original equipment manufacturers and regional private label networks.
We organize container packing, custom documentation, and shipping coordinates out of Tianjin Port, offering FOB, CIF, or DDU delivery terms depending on project location.
Beyond NBR/PVC pipe and sheet rolls, we provide necessary thermal accessories, including high-adhesion elastomeric glues, self-adhesive tapes, and jointing systems.
