Kingflex
Explore our foundational range of thermal insulation sheet rolls, soundproofing systems, and cryogenic specialized barriers certified for global architectural and industrial environments.
The modern HVAC, petrochemical, and construction sectors face unprecedented demands for decarbonization, thermal efficiency, and moisture management. Self-adhesive thermal insulation sheets have transitioned from a luxury specification to a baseline requirement. By integrating high-performance adhesive backings directly onto closed-cell NBR/PVC elastomeric substrates, manufacturers eliminate the highly variable step of manual adhesive coating on-site. This significantly limits volatile organic compound (VOC) emissions, standardizes bonding strength, and accelerates project timelines by up to 50%.
In Europe, the Americas, and APAC, green building initiatives like LEED and BREEAM necessitate materials that perform consistently under thermodynamic strain while minimizing environmental footprint. Structural condensation represents one of the primary drivers of localized structural failure and IAQ (Indoor Air Quality) degradation. Safe containment of ambient moisture requires a material with an exceptionally high water vapor diffusion resistance ($\mu$ value) paired with a low, stable thermal conductivity ($\lambda$ value).
Our elastomeric NBR/PVC matrix undergoes specialized vulcanization and micro-foaming processes to yield precise cell structures.
Maintains a stable low thermal conductivity ($\le 0.034$ W/m·K at 0°C). Our closed-cell structure blocks air movement, reducing structural convection loops inside the insulation layer.
Capable of sustained thermal containment across a broad operating envelope, from cryogenic system requirements (-200°C) up to HVAC and industrial steam limits (+105°C).
Formulated with advanced fire-retardant elements. Meets critical criteria such as Class 0 and Class 1 ratings under BS 476, self-extinguishing without contributing to hazardous smoke development.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Our research, development, and state-of-the-art production departments are situated in Dacheng, China—historically recognized as the capital of green building materials. As an energy-saving, environmentally conscious enterprise, we concentrate on the entire product lifecycle: from chemistry R&D to factory processing, global sales, installation guidelines, and post-sale technical support.
Founded by the Jinwei Group, which possesses a robust history spanning more than 40 years, our roots date back to the group's founding in 1979. Kingway Group stood as the first manufacturer of thermal insulation materials north of the Yangtze River. Today, this profound heritage forms the bedrock of our manufacturing discipline, enabling us to serve major global civil engineering developments and industrial plants.
Our manufacturing complex utilizes optimized automation lines to achieve scale, speed, and standard-compliant consistency.
Kingflex operates 5 large-scale automatic assembly lines. With an annual production capacity exceeding 600,000 cubic meters, our factory handles massive volume requirements for major infrastructure project pipelines without compromising quality. Reflecting our technical capability and process reliability, we are designated as a production enterprise for key governmental bodies, including the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry.
Our China-based facility delivers significant logistical and cost advantages: seamless access to polymer raw materials, integrated chemical processing ecosystems, and proximity to international container ports. For global procurers, this translates into consistent supply chains, stable lead times, and competitive price structures compared to regional manufacturers operating at smaller scales.
Continuous chemical analysis, microstructure inspection, and fire performance testing inside our specialized laboratories.
Our materials science team continuous optimizes the polymer matrix, adjusting NBR/PVC ratios to enhance flexibility, moisture vapor resistance, and long-term aging parameters.
Rigorous flame propagation and smoke density analyses are performed inside custom smoke chambers, ensuring absolute compliance with fire protection directives worldwide.
Testing the shear and peel strength of our self-adhesive backings across high-temperature conditions prevents delamination on curved surfaces and vertical air ducts.
Our commitment to Quality Assurance is verified by independent third-party laboratories. Every batch maintains full traceability.
Every square meter of Kingflex self-adhesive rubber foam is printed with a production batch code. This code traces the specific raw material lot, vulcanization temperatures, density metrics, and adhesive batch runs, securing end-to-end reliability for critical commercial builds.
Free from CFCs, HFCs, and polybrominated diphenyl ethers (PBDEs). Kingflex products prevent fiber shedding and dust release, ensuring suitability for high-hygiene requirements in hospitals and microelectronics facilities.
