Kingflex
Explore our flagship thermal and acoustic insulation lines engineered to support diverse HVAC, building, and industrial piping configurations.
As modern building codes prioritize strict energy efficiency and carbon neutrality, architectural and mechanical specifications call for insulation systems that deliver continuous thermal resistance, condensation prevention, and advanced acoustic properties. Rubber foam insulation rolls (NBR/PVC-based elastomeric foams) have emerged as the standard solution for HVAC systems, cold storage piping, and process industrial pipelines.
Global procurement teams prioritize compliance certifications like BS 476, CE, REACH, RoHS, and ASTM standards. Sourcing directly from modern manufacturers ensures high-volume consistency, customized roll geometry (from 6mm to 50mm thickness), and critical traceable production cycles. These capabilities are crucial in preventing material fatigue, maintaining flame retardance, and securing projects against operational breakdowns.

Kingflex Insulation Co., Ltd. is a manufacturing and trading combo for thermal insulation systems. Located in Dacheng, the heart of China’s green-building material cluster, our production division utilizes 5 fully automated assembly lines. Our factory integration ensures that material chemistry, vulcanization density (40-55kg/m³), and continuous foaming ratios are monitored in real-time.
By controlling both NBR and PVC polymer compounding, we mitigate supply chain disruptions and offer stable thermal conductivity properties. This vertical integration makes us a trusted provider for the Ministry of Energy, Ministry of Electric Power, and the Ministry of Chemical Industry, and allows us to deliver large-scale project materials on time.

It is mainly used for HVAC ducts, air conditioning pipes, building thermal insulation, industrial pipeline cold insulation, and sound insulation. Its closed-cell structure makes it particularly effective in stopping moisture ingress and preventing condensation on cold surfaces.
Yes, our rubber foam insulation products are fire retardant, meeting global safety standards such as BS 476 Part 6 & 7 (Class 0 and Class 1), UL94, and ASTM. They are self-extinguishing when removed from a direct flame source.
Rubber foam is a flexible, closed-cell, moisture-proof material suitable for low-to-medium temperature ranges and HVAC ducting. Rock wool is a high-density, fibrous material that withstands high temperatures, making it suitable for high-temperature industrial steam piping and specialized fire barriers.
Yes, we support comprehensive OEM services. We can customize dimensions, thicknesses (from 6mm up to 50mm), surface facings (like aluminum foil or self-adhesive backings), and colors to match specific project and engineering requirements.
Our products have passed BS 476, CE, REACH, RoHS, UL94, ASTM, and other international certifications, ensuring product quality and compliance with global environmental regulations.
Yes, Kingflex products have traceability. We maintain manufacturing batch codes, raw material inspection files, and shipment documentation to ensure quality tracking from our production lines to the job site.
We produce sheet rolls and insulation boards ranging from 6mm to 50mm in thickness. This range allows mechanical engineers to specify exact thermal barrier requirements for varying environmental conditions.
Under standard operational conditions and proper installation, the expected service life is 10 to 15 years. Using protective exterior cladding in outdoor applications can extend the product's lifespan further.
