Kingflex
Explore our primary range of standard and high-performance industrial elastomeric foam sheets, tubes, and rolls engineered for superior thermal efficiency and environmental resistance.
Kingflex Insulation Co., Ltd. stands as a premier manufacturing and trading conglomerate dedicated to top-tier thermal insulation technology. Nestled in Dacheng, China—a globally recognized hub for green building materials development—our facility integrates advanced research, energy-conservation engineering, and precision production under a single operational standard.
Founded by the Jinwei Group, whose rich history dates back to 1979 as the first pioneer of thermal insulation materials north of the Yangtze River, Kingflex draws on over 40 years of industrial wisdom. We take energy conservation and consumption mitigation as our primary values, supplying engineered insulation systems that lead international development trends in infrastructure building materials.
Serving petrochemical, national defense, HVAC and cryogenic industries globally.
By implementing cutting-edge manufacturing automation, Kingflex operates five large-scale continuous automatic assembly lines with a total annual production output surpassing 600,000 cubic meters. Our facilities are designated as production systems by key state departments, including the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry.
Continuous vertical and horizontal vulcanization processes produce uniform cell structures, which keeps water vapor permeability exceptionally low and provides long-term thermal isolation properties.
Five high-speed automatic production lines operate 24/7. This guarantees rapid delivery and consistent quality for major municipal and industrial construction pipelines worldwide.
Every roll, sheet, and pipe insulation sleeve carries physical and digital identification. Raw material chemistry and curing histories are logged to ensure reliable trackability.
Our team consists of 8 professional engineers in our dedicated R&D department, 6 specialized international sales specialists, and 230 skilled production technicians.
Collaboratively, they strive to deliver top-tier energy-saving insulation systems. Our engineers focus on key material features, including high flame resistance, high-temperature tolerance, and sound-absorption efficiency, ensuring our solutions perform reliably across diverse project specifications.
As sustainability regulations tighten globally, the HVAC and industrial insulation sectors face challenges related to thermal efficiency, fire safety, and emissions. Kingflex is committed to a technical roadmap that prioritizes green chemistry and high performance:
Phasing out older blowing agents in favor of eco-friendly gas configurations that yield zero Ozone Depletion Potential (ODP) and zero Global Warming Potential (GWP).
Combining the flexibility of NBR/PVC closed-cell foams with high-temperature silica aerogels, aiming to push the continuous operating limit past 150°C.
R&D focused on next-generation halogen-free flame retardants, targeting stricter smoke-density classifications in European rail and high-rise codes.
Our engineers regularly perform testing on cell structures, density gradients, and vapor barrier performance. Using precision analytical equipment, we continuously refine physical properties to meet demanding operating specifications.
Prevents condensation on chilled water pipes and ductwork, reducing thermal losses and improving indoor air quality by preventing mold growth in commercial systems.
Provides consistent insulation for industrial hot water, low-pressure steam, and process piping. It resists environmental weathering, chemical exposure, and mechanical vibrations.
Engineered multi-layer solutions maintain structural integrity down to -200°C. They protect against moisture ingress and condensation, which can lead to pipe corrosion under insulation (CUI).
We manufacture premium foam rubber insulation products tailored to various installation requirements. Here are the core specifications of our standard range:
Central air conditioning ductwork, industrial tanks, structural walls, acoustic machine rooms, rail carriage sub-floors, and cold rooms.
Condensate lines, HVAC copper refrigerant lines, industrial steam routing, cold chain facilities, chemical process lines, and solar water heaters.
Highly flexible thermal tube for commercial HVAC.
Chemically treated for harsh industrial systems.
Enhanced flexibility for tight radius installations.
Standard closed cell formulation for heat/cold.
High resilience elastomeric tube for HVAC lines.
Optimized density for heat pump installations.
Engineered for ultra-low temperature environments.
Withstands service conditions down to -200 °C.
Multi-layered thermal barrier preventing vapor ingress.
Specialized formulation for liquefied gases.
High density mineral fiber board for thermal stability.
Flexible high-temp mineral wrap for industrial vessels.
Navigating global regulatory landscapes requires verified testing credentials. Kingflex materials meet rigorous international benchmarks to streamline project approvals:
Certified to BS 476 (Class 0 & 1), UL 94 V-0, and ASTM E84. These certifications ensure low flame spread and minimal smoke development in commercial spaces.
Compliant with REACH and RoHS protocols, guaranteeing the elimination of brominated flame retardants, heavy metals, and CFC gases.
Our plants employ tracking identifiers linked to individual batches, documenting curing parameters, raw material certificates, and quality checks.
Authorized certifications showing compliance across European, American, and regional specifications.
