Kingflex
Engineered high-performance elastomeric rolls designed to comply with local European construction norms.
As Belgium advances its commitment to the European Green Deal and regional energy performance requirements—such as the EPB (Energieprestatie en Binnenklimaat) standards in Flanders, PEB in Wallonia, and the Brussels-Capital Region regulations—the demand for advanced thermodynamic management has intensified. Industrial hubs like the Port of Antwerp-Bruges and urban developments in Brussels require state-of-the-art insulation materials capable of reducing energy losses to absolute minimums.
NBR/PVC elastomeric rubber foam insulation sheet rolls play a crucial role in these decarbonization efforts. Their closed-cell structural configuration acts as a superior barrier against heat transfer and moisture intrusion. Designed to handle severe humidity profiles typical of the Belgian Maritime Climate, our high-density rubber foam rolls protect critical infrastructure from Corrosion Under Insulation (CUI) while maintaining structural integrity over decades of continuous operation.

| Property | Test Standard | NBR/PVC Elastomeric Sheet Roll Value | Advantage / Purpose |
|---|---|---|---|
| Thermal Conductivity ($\lambda$) | ASTM C518 / EN 12667 | $\le 0.034 \text{ W}/(\text{m}\cdot\text{K})$ at 0°C | Minimizes energy transmission, lowers cooling costs. |
| Water Vapor Diffusion ($\mu$) | EN 12086 / ASTM E96 | $\ge 10,000$ | Prevents moisture intrusion without external jackets. |
| Reaction to Fire | EN 13501-1 / BS 476 Part 7 | Class B-s3, d0 / Class 1 | Self-extinguishing, limits toxic smoke development. |
| Density Range | ASTM D1622 | $40 - 55 \text{ kg/m}^3$ | Optimizes mechanical flexibility and thermal boundary resistance. |
| Service Temperature Limit | EN 14706 / ASTM C534 | -40°C to +105°C (Cryogenic series down to -200°C) | Covers standard HVAC, district heating, and chemical pipelines. |
| Compression Resilience | ASTM D1056 | $\ge 80\%$ recovery | Resists mechanical load deformations at pipe hanger points. |
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for high-performance thermal insulation systems. Our primary research and production installations are situated in Dacheng, China—historically recognized as the capital of energy-efficient green-building materials.
Established as a core subsidiary of the Jinwei Group, which possesses a market heritage dating back to 1979 (the first specialized thermal insulation supplier north of the Yangtze River), Kingflex has grown from regional operations into a global scale supplier. Today, we supply standard-setting materials to over 66 nations, integrating advanced chemical engineering, continuous testing, and on-site support.
Our dedicated R&D division includes 8 professional thermodynamic engineers working alongside 230 manufacturing specialists. By refining polymerization and vulcanization parameters, we maintain an average closed-cell yield of over 98%, far exceeding standard market outputs.
With high gas and raw material costs in Europe, securing competitive direct supply of NBR/PVC elastomeric rubber foam has become critical for Belgian contractors. Kingflex operates 5 large-scale automated continuous vulcanization extrusion lines. This setup delivers high consistency and price stability compared to localized batch production.
Our automated monitoring system measures continuous density, thickness, and foaming distribution in real time. We produce over 600,000 cubic meters annually, allowing us to maintain stable, bulk supply pools for major projects.
For Belgian clients, we offer optimized shipping packages. Shipments are loaded into 40ft High Cube containers and sent via direct routes from Chinese marine gateways directly to the Port of Antwerp-Bruges or Zeebrugge. This logistics pipeline ensures short transit times, minimized handling, and reliable scheduling.
Typical installation systems for standard HVAC projects, district heating networks, and heavy industrial facilities.
Designed for large HVAC ductwork in logistics hubs and commercial office spaces across Brussels and Flanders. The high-density closed-cell structure blocks air condensation and limits environmental energy losses.
Engineered for refrigeration systems, central AC piping, and chemical process piping. Our extruded foam pipes protect line systems from freezing, cracking, and energy losses in industrial complexes.
Our testing processes ensure every production batch meets international ASTM, BS, and EN requirements.
Kingflex products are certified by independent testing laboratories to meet international standards.
Client feedback confirming product quality, compliance, and shipment delivery.
Technical and logistics answers for building engineers, estimators, and procurement managers in Belgium.
It is mainly used for HVAC ducts, air conditioning pipes, building thermal insulation, industrial pipeline cold insulation, and sound insulation. Its closed-cell structures make it highly efficient at preventing condensation on chilled water lines and reducing thermal losses on hot water pipes.
Yes, our rubber foam insulation products are flame retardant, meeting standard building and industrial project fire safety codes, including British Standard BS 476 Class 1, European EN 13501-1 Class B-s3,d0, and American UL94 specifications.
Rubber foam is flexible, closed-cell, and moisture-proof, making it suitable for HVAC and chilled water pipeline systems to control condensation. Rock wool is high-temperature resistant and fireproof, suitable for high-temperature industrial steam piping and commercial structural fire walls where moisture absorption is not a primary concern.
Yes, we support OEM and custom services. We can customize density, sheet roll thicknesses (from 6mm to 50mm), pipe inner diameters, custom self-adhesive backings, and aluminum foil surface options to meet specific project needs.
Our products have passed BS 476, CE, REACH, RoHS, UL94, ASTM, and other international certifications, ensuring product quality and compliance with global standards.
Yes, Kingflex maintains batch traceability. Every production run is coded, allowing us to trace raw materials, production line conditions, and QC inspection data to ensure consistency and accountability.
We can produce thicknesses from 6mm up to 50mm. Standard thicknesses include 6mm, 9mm, 13mm, 19mm, 25mm, 32mm, 40mm, and 50mm, available in standard widths and custom lengths.
Under normal operational conditions and when installed according to manufacturer specifications, the typical service life is 10 to 15 years. Outdoor installations require UV-protective coatings or foil cladding to prevent weathering degradation.
