Kingflex
Explore our heavy-duty industrial pipe and sheet insulation systems, designed for global energy-saving compliance.
Within modern industrial and commercial construction ecosystems, Rubber Foam Insulation Sheet Rolls are critical parameters in reducing carbon emissions. Specifically, the emergence of the green color variant has gained massive commercial momentum globally. Green rubber foam is not merely an aesthetic choice; it acts as a crucial industrial identifier representing specific safety compliance, structural formulation enhancements, and environmental designations.
In highly regulated markets like Europe, North America, and parts of the Asia-Pacific, green rubber foam denotes low-halogen, non-toxic, or custom class-rated HVAC and process pipe insulation. Global Engineering, Procurement, and Construction (EPC) firms specify green insulation to demarcate high-efficiency chilled water loops, geothermal piping systems, and sustainable green-building zones certified under LEED or BREEAM systems.
Kingflex Insulation Co., Ltd. operates in Dacheng, China—the undisputed capital of green building thermal insulation materials.
Established under the elite umbrella of the Jinwei Group (founded in 1979 as the pioneer manufacturer of thermal insulation materials north of the Yangtze River), Kingflex has structured modern continuous foaming technology that achieves a closed-cell rate of over 98%. By utilizing vertical supply chains and automated high-throughput continuous vulcanization tunnels, China factories bypass structural bottlenecks common to Western operations, resulting in a 25-35% unit cost reduction reflected directly in our Pricelist.
Our operation prioritizes energy conservation and consumption reduction as the core concepts. We provide comprehensive thermal insulation, cold insulation, and noise reduction systems through consultation, research, design, production, and installation guidance.
Kingflex insulation sheets and rolls are fabricated from high-grade Nitrile Butadiene Rubber (NBR) and Polyvinyl Chloride (PVC) resins. This hybrid matrix provides physical elasticity, low thermal conductivity, and structural resistance to water vapor intrusion.

Where Kingflex Green Rubber Foam delivers maximum insulation efficiency and energy conservation.
Used to prevent thermal losses and moisture condensation in large air ducts, air conditioning chillers, and distribution lines. The green color aids engineers in differentiating return air, supply air, or specialized zones during inspection cycles.
For chemical facilities, petrochemical lines, gas storage, and cryogenic networks, Kingflex has designed systems capable of handling ultra-low temperatures, keeping energy loss to a minimum and preventing critical stress cracking.
Applied extensively in schools, hospitals, office spaces, and commercial malls. With a physical elasticity rating of >80%, it dampens noise transmission across structural frames, air vents, and wastewater drainage systems.
Provides highly durable external shielding against corrosive chemicals, atmospheric moisture, and structural surface wear on heavy piping systems and product storage tanks in demanding manufacturing complexes.
Ensuring each batch meets stringent requirements of local architectural codes and international protocols.
Kingflex deploys 8 specialized R&D engineers focused entirely on polymer cell architecture, density tuning, and toxicity minimization. By continuously upgrading NBR formulation techniques, the team has achieved an optimal molecular structure that resists aging and thermal leakage over a lifetime of 10 to 15 years.
With an international sales force of 6 experts and a dedicated production workforce of 230 technicians, we deliver fully traceable production cycles. Every single batch of Green Rubber Foam is labeled with unique lot tracking markers, tracing back to the raw polymer raw batch, curing temperature records, and warehouse quality control testing sheets.
Our commitment to compliance is proven by global testing organizations. Kingflex has secured key certifications including BS 476, CE, REACH, RoHS, UL94, and ASTM. This guarantees that importing products to Europe, the Americas, or Oceania satisfies all technical, environmental, and fire safety codes.
Real-world feedback and trace records from international EPC managers and global building system distributors.
Kingflex insulation sheets, tubes, and rolls are systematically integrated into high-profile building envelopes, municipal district cooling installations, and chemical manufacturing complexes across 66 countries.
We work closely with procurement officers, providing custom thickness profiles, dynamic quotes, and detailed logistics planning for large structural insulation projects.
Inside Dacheng's most advanced environmental insulation production facility.
To support high demand and minimize product delivery cycles, our facility leverages continuous raw material mixing, extrusion molding, pre-heating tunnels, and temperature-controlled curing machinery. This system ensures consistent physical performance throughout each roll of green insulation.
Technical insights and guidance for engineers, building experts, and procurement directors.
It is mainly used for HVAC ducts, air conditioning pipes, building thermal insulation, industrial pipeline cold insulation, and sound insulation. Its high closed-cell structure prevents moisture condensation on chilled water pipes, maintaining system efficiency.
Yes, our rubber foam insulation products are flame retardant, meeting BS 476 (Class 0 and Class 1), UL94, and ASTM E84 safety standards, making them suitable for commercial building projects.
Rubber foam is flexible, closed-cell, and moisture-proof, suitable for HVAC and chilled water piping. Rock wool is highly temperature-resistant and fireproof, making it better suited for industrial high-temperature steam pipelines.
Yes, we support OEM/ODM services, including customized colors (like green), densities, self-adhesive backings, and aluminum foil laminations to meet specific project needs.
Our products have passed BS 476, CE, REACH, RoHS, UL94, ASTM, and other international certifications, ensuring compliance with global environmental and safety standards.
Yes. Every production run has a distinct batch number. This tracking covers the entire production process from raw polymer checking up to the final packaging stage.
Our production lines manufacture sheets and rolls in thicknesses from 6mm up to 50mm, matching various insulation thermal resistance requirements.
Under standard indoor or protected outdoor operating conditions, Kingflex NBR/PVC insulation has an expected lifetime of 10 to 15 years, depending on local installation quality and environmental exposure.
For applications where specialized green color-coding is not required, our standard Black Rubber Foam Sheet Rolls offer matching thermal properties. This material features low moisture permeability, structural density between 40-55 kg/m³, and a temperature range of -40°C to +105°C, providing a cost-effective choice for general building projects.
Engineered for pipeline systems, these pre-formed black tubular sections fit pipe diameters from 6mm up to 114mm. They help prevent heat gain or loss on domestic hot water pipes and mechanical lines, while reducing risk of pipe freezing and cracking.
