Kingflex Insulation Co., Ltd. is a leading integrated manufacturing and trading conglomerate specializing in high-end thermal and cryogenic insulation products.
Headquartered in Dacheng, China—historically recognized as the capital of green building materials—our research, development, and production facility represents the pinnacle of energy-saving, environmentally conscious manufacturing. By taking consumption reduction as our core corporate mission, Kingflex offers clients a full suite of services: from advanced material consulting and targeted R&D to factory-precision production, structural installation guidance, and dedicated post-sale engineering support.
Founded by the Jinwei Group, which holds a rich heritage dating back to 1979 (being the first manufacturer of thermal insulation materials north of the Yangtze River), Kingflex has synthesized four decades of chemical formulation expertise with modern automation technologies.
Global procurement specialists demand high-volume production without compromising strict tolerances. Kingflex meets this challenge by utilizing advanced Industry 4.0 production frameworks.
At present, Kingflex operates 5 large-scale, fully automated continuous assembly lines. This production setup guarantees an annual production capacity exceeding 600,000 cubic meters. Our reliability has made us a designated production enterprise certified and trusted by the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry.
This massive scale ensures that large commercial construction jobs in Australia, industrial piping projects in Europe, and extreme-low-temperature gas processing plants globally receive consistent products with low lead times. Our supply chain is built for resilience, utilizing raw NBR/PVC polymers optimized for elasticity and cell integrity.
Modern architecture and industrial chemical systems require targeted thermal barrier performance. Our closed-cell rubber elastomeric structures are tailored to meet these demanding scenarios.
Material Structure: Evenly and fully foamed elastomeric matrix, closed-cell rate > 98%.
Standard Dimension: Thickness ranges from 6mm to 50mm, with density maintained between 40-55 kg/m³.
Core Performance: Service temperature range of -40℃ to 105℃, compression resilience > 80%, low thermal conductivity, and high moisture resistance factor (mu).
Primary Applications: HVAC duct wrap, commercial roofing, basement thermal insulation, acoustic damping for ventilation rooms, and marine structural insulation.
Material Structure: High-precision extruded tubing designed for tight-fitting pipe jackets.
Standard Dimension: Wall thickness from 9mm to 40mm, Internal Diameter (ID) ranging from 6mm to 114mm.
Core Performance: Prevents pipeline freeze-thaw cracking, limits condensation, and eliminates corrosion under insulation (CUI) risk.
Primary Applications: Chilled water pipes, industrial steam lines, solar thermal loop systems, and building water infrastructure.
Material Structure: Multi-layer composite elastomeric systems engineered for extreme thermal gradients.
Thermal Range: Operates efficiently down to -200°C (-328°F).
Core Performance: Resists micro-cracking and structural embrittlement under intense cold. Eliminates vapor entry paths.
Primary Applications: Liquid Natural Gas (LNG) terminals, cryogenic pipelines, ethlyene processing units, and aerospace thermal control.
Driving structural efficiency and ecological compatibility via advanced material science.
Our ongoing formulation roadmap focuses on next-generation chemical blowing agents. We are phasing out fluorinated gases to implement CO2-expanded technologies, achieving zero Ozone Depletion Potential (ODP) and negligible Global Warming Potential (GWP), meeting strict European and Australian green building requirements.
We are actively researching composite organic-inorganic synergetic flame retardants. The goal is to provide BS 476 Class 0 and UL 94 V-0 ratings while minimizing smoke density and toxicity, ensuring optimal safety in confined areas like tunnels, trains, and medical wards.
By adjusting our NBR/PVC polymer backbone ratio and integrating cross-linked alkadiene structures, our R&D group has expanded materials' physical ductility at -200°C. This prevents stress fractures caused by expansion and contraction in LNG operations.
Importing construction products into Australia requires complying with local building and performance codes. Kingflex is committed to meeting these strict specifications.
Australian construction specifications, particularly NCC Volume 1 Section C (Fire Resistance) and Section J (Energy Efficiency), require third-party validated materials. Kingflex NBR/PVC foam insulation maintains stable k-value profiles and high vapor diffusion resistance (Foil faced variants achieve AS/NZS 1530.3 compliance for flame, smoke, heat, and ignition indices).
All Kingflex production runs feature end-to-end batch traceability.
From chemical feedstock tracking to final extrusion curing, our ISO-9001 quality program tracks all steps. This means commercial contractors in Melbourne, Sydney, or Brisbane can present fully verifiable compliance packs to local certifiers.
