Kingflex
Direct procurement pipelines for high-specification NBR/PVC elastomeric thermal and acoustic barrier products optimized for international building codes and industrial infrastructure.
High-performance buildings demand strict thermal management. Our closed-cell rubber foam insulation effectively mitigates heat gain and condensation in chilled water systems, VRF lines, and air handling equipment. Operating temperatures range from -40°C to 105°C, maintaining a stable thermal conductivity coefficient to cut energy expenditures across commercial centers, hotels, and clinical environments.
Within chemical and petrochemical processing, industrial pipelines require continuous temperature control to prevent viscosity drops, fluid crystallization, or explosive reactions. Kingflex products offer robust resistance against high humidity, salt spray, and atmospheric contaminants, ensuring long-term thermal stabilization for steam systems and chemical storage tanks.
Handling liquefied gases (such as LNG, oxygen, and nitrogen) demands advanced cryogenic insulation barrier integration. Kingflex elastomeric systems remain flexible and crack-resistant under extreme cold, preventing ambient heat entry and heavy frost formation. This guarantees process continuity and lowers the strain on cooling compressors.
Established by the Jinwei Group (founded in 1979, the pioneer of industrial thermal insulation manufacturing north of the Yangtze River), Kingflex Insulation Co., Ltd. is a leading integrated manufacturing and trading system. Our state-of-the-art manufacturing plant is located in Dacheng, China—widely recognized as the premier capital of energy-saving, green-building technology.
Our operations leverage 5 high-speed, fully automated assembly lines that output more than 600,000 cubic meters of high-density elastomeric foam material annually. As a designated manufacturer trusted by the Ministry of Energy, Ministry of Electric Power, and the Ministry of Chemical Industry, our products comply with complex building specifications and critical marine/military regulations.
Our R&D division has 8 professional engineers, supported by 6 international sales consultants and 230 technicians. This workforce maintains strict adherence to quality systems, ensuring traceabiity and compliance on every shipment.
Equipped with thermal conductivity meters, optical oxygen index testers, smoke density chambers, and compression testing units to evaluate every batch against international fire and insulation standards.
Full verification under BS 476 Part 6 & 7, CE Mark, REACH, ROHS, UL94 (class V-0/5V), and ASTM testing protocols to ensure safety compliance and durability in overseas markets.
Our products offer a service life of 10 to 15 years, even in challenging environmental conditions, reducing long-term replacement costs.
Our premium closed-cell NBR/PVC elastomeric formulations are engineered with a uniform cell structure of 40 to 55 kg/m³ density. This configuration limits heat transfer and locks out moisture, preventing corrosion under insulation (CUI).

How Kingflex addresses complex thermal and acoustic problems in commercial and industrial settings.
Building fire safety is a top priority. Our elastomeric compounds are formulated with halogen-free flame retardants, ensuring they are self-extinguishing and emit minimal smoke. Closed-cell structures prevent water ingress, stopping corrosion under insulation (CUI) to extend the lifespan of carbon steel and copper pipes.
High-velocity fluid transport and mechanical vibration generate structural noise. Our open-cell NBR/PVC panels absorb sound waves across a broad frequency spectrum. This makes them ideal for lining mechanical rooms, enclosing waste pipes, and soundproofing heavy machinery.
Cryogenic piping systems operating below -150°C face extreme thermal gradients that can cause materials to crack. Our multi-layer cryogenic elastomeric setups remain flexible, preventing atmospheric moisture ingress to avoid ice buildup and ensure steady thermal resistance.
The global insulation sector is shifting toward products with low environmental impact and improved thermal efficiency. Our research program focuses on developing high-performance solutions to meet these requirements.
Transitioning to next-generation chemical blowing agents with zero Ozone Depletion Potential (ODP) and extremely low Global Warming Potential (GWP), meeting strict environmental regulations.
Developing silica-aerogel infused NBR matrices to achieve exceptionally low thermal conductivity (λ < 0.028 W/m·K) while preserving structural flexibility.
Integrating conductive carbon nanotube networks to monitor moisture levels in real-time, detecting potential corrosion before it damages the pipes.
