Discover our comprehensive range of high-density NBR/PVC elastomeric rubber foam materials and HVAC system integration components.
Modern HVAC systems, VRF layouts, and industrial cryogenic structures demand exceptional thermodynamic control. At the heart of these installations lies the insulated copper coil—a specialized pipeline system combining high-purity, seamless copper tubes with premium closed-cell NBR/PVC elastomeric thermal insulation. This union addresses two main points: efficient refrigerant transportation and the complete prevention of surface condensation and thermal loss.
As a leading Chinese industrial group with over four decades of thermal insulation expertise, Kingflex Insulation Co., Ltd. (originally established under the Jinwei Group since 1979) delivers integrated HVAC/R piping and insulation solutions. Our systems are engineered to withstand extreme environment variants while meeting international compliance structures (BS 476, CE, REACH, RoHS, UL94, and ASTM).
The global HVAC market is undergoing rapid change driven by green building codes (such as LEED and BREEAM) and regional energy saving initiatives. The trend has shifted from post-insulating copper lines in the field to using factory pre-insulated copper coils. This transition offers several key advantages:
Global HVAC contractors, OEM companies, and distributors focus on total cost of ownership (TCO) rather than unit cost alone. When evaluating an insulated copper coil supplier, procurement engineers focus on several performance factors:
First, thermodynamic stability. High-density elastomer insulation must maintain a thermal conductivity coefficient (λ) below 0.034 W/m·K at 0°C. If this value fluctuates, the system will consume more energy. Second, fire safety compliance. For commercial high-rise buildings and public infrastructure, materials must satisfy strict fire safety standards such as BS 476 Part 7 Class 1 or Class 0, and UL94 V-0 ratings.
Kingflex's production complex is located in Dacheng, China—a major hub for green building materials. Our facility features five automated assembly lines, with an annual capacity exceeding 600,000 cubic meters. This scale enables us to support major commercial projects while maintaining stable lead times.
Our Quality Assurance system monitors raw material inspection, precise compounding of the NBR/PVC polymers, controlled foaming, and high-pressure extrusion. As a designated supplier for the Ministry of Energy, Ministry of Electric Power, and Ministry of Chemical Industry in China, Kingflex provides product traceability from raw materials to shipped products.
Established by the Jinwei Group (which has over 40 years of industrial history dating back to 1979), Kingflex was the first manufacturer of thermal insulation materials north of the Yangtze River. This history provides us with deep manufacturing expertise.
Our team includes 8 professional R&D engineers, 6 international sales specialists, and 230 manufacturing specialists. This cross-functional team ensures our products match local standards and project needs across different regions.
