Explore our elite range of elastomeric rubber foam materials, insulation tapes, and cryogenic systems designed to minimize energy loss and prevent condensation.
Kingflex Insulation Co., Ltd. represents a premier global manufacturing and trading conglomerate dedicated to top-tier thermal and cryogenic insulation solutions. Strategically situated in Dacheng, China—historically recognized as the capital of green-building materials—our corporation integrates cutting-edge Research & Development with massive production capacities and responsive international trading networks.
Taking energy conservation, emission containment, and long-term sustainability as our absolute core guidelines, we support global industries by offering end-to-end services. This spans upfront professional consulting, robust custom material formulations, high-volume automated manufacturing, direct site installation supervision, and comprehensive post-purchase traceability protocols.
Established originally under the aegis of the renowned Jinwei Group (founded in 1979), our corporate history stretches back over 40 years. Pioneering as the very first manufacturer of thermal insulation materials north of the Yangtze River, Jinwei Group provided the foundational expertise, structural resources, and engineering heritage that today empower Kingflex to set industry standards worldwide.
Our dedicated operations run with 5 fully automated assembly lines delivering an annual output exceeding 600,000 cubic meters. Because of our strict quality benchmarks, we have been designated as a trusted supplier by the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry.
Under the double-carbon target, standard HVAC systems are transitioning into high-efficiency, environment-friendly structures that demand zero moisture permeability and minimal thermal bridging.
Global regulatory frameworks (such as ASHRAE 90.1, the EU Green Deal, and energy-saving building codes) demand structural reductions in heat transfer. As global temperatures climb, commercial buildings, supermarkets, and industrial centers require larger, high-capacity HVAC units. Selecting Kingflex NBR/PVC closed-cell foams allows operators to prevent heat loss and ensure systemic HVAC energy efficiency.
When warm, moist air contacts cold refrigerant lines, condensation occurs, causing drips, mold growth, and structural corrosion (under-insulation corrosion). With a closed-cell configuration exceeding 98% density uniformity, Kingflex acts as an impenetrable barrier, blocking water vapor transmission and extending the service life of metal pipes to 10–15 years.
Modern commercial buildings demand acoustic comfort alongside thermal protection. In hotels, hospitals, and high-rise residences, air flow and mechanical vibration generate continuous structure-borne noise. Kingflex open-cell and customized elastomeric foam combinations provide superior sound-absorbing ratings to damp vibrations and lower operational noise levels.
We manufacture high-grade closed-cell elastomeric foams in both Sheet Roll and Pipe form factors, optimized for different line diameters and equipment layouts.
Designed for large ducts, process equipment chambers, tanks, and wide industrial pipe systems.
Optimized for standard copper and steel pipelines, central air-con lines, and water lines.
Our dedicated Research & Development Department is staffed by 8 professional materials engineers. Equipped with advanced thermal property testing systems, environmental simulation chambers, and precision chromatography, they focus on improving polymer matrix formulations.
Working alongside them are 6 professional international sales coordinators and a production workforce of 230 workers. This collaborative effort ensures that custom material modifications—such as low-toxicity fire properties or cryogenic flexibility—transition smoothly from laboratory testing to large-scale production.
Every production batch is tested in our quality assurance laboratory to ensure consistent physical properties. We verify density uniformity, cell structure, tensile strength, and water vapor permeability.
Our products are tested for compliance with leading international fire safety and engineering standards. The Kingflex insulation system maintains reliable performance over decades of thermal cycles.
International industrial projects require certified compliance. Kingflex insulation solutions undergo testing to verify their physical, thermal, and chemical safety properties.
Our product catalog meets global HVAC, construction, and petrochemical requirements, including:
From standard commercial buildings to specialized cryogenic facilities, our elastomeric rubber foams protect critical piping networks.
Used in central air conditioning chilled water lines, hot water systems, and condensate pipe layouts. Kingflex products prevent condensation and heat gain in hotels, corporate headquarters, airport terminals, and shopping centers.
Designed for liquified gas networks and petrochemical pipelines operating down to -200℃. Our cryogenic NBR/PVC formulations prevent insulation cracking and thermal contraction failure.
Applied in mechanical equipment rooms, high-rise shafts, and air handling units. Open-cell configurations provide thermal barrier protection and reduce environmental noise.
We maintain open communication with our global distribution partners and engineering clients, ensuring prompt technical answers and direct factory tracking.
