Browse our baseline high-performance elastomeric and nitrile rubber configurations designed for modern architectural and mechanical acoustic insulation demands.
Kingflex Insulation Co., Ltd. stands as a premier manufacturer and global trading powerhouse specializing in high-grade thermal and acoustic insulation systems. Our research and development center is anchored in China’s green building materials capital (Dacheng), focusing strictly on energy-saving, environmentally sound, and high-performance elastomeric foam and rock wool solutions.
We approach building noise and heat containment comprehensively: offering technical consultations, customized product development, rigorous production control, onsite installation guidance, and dedicated post-sale engineering services to optimize structural acoustical footprints worldwide.
Operating under our mother group—the Jinwei Group, established in 1979—we hold over 40 years of pioneering technical lineage in thermal materials and sound barriers. We operate 5 state-of-the-art automatic production lines yielding over 600,000 cubic meters annually, keeping us at the forefront of global construction specifications.
In the United States, commercial engineering and industrial processing plants encounter some of the most rigorous acoustical and safety benchmarks globally. Navigating federal, state, and local standards demands highly specialized sound insulation designs.
US building codes demand strict fire compliance. Materials used in HVAC plenums must meet the ASTM E84 standard with a flame spread index under 25 and smoke-developed index under 50. Kingflex elastomer solutions fulfill Class Class 0/Class A classifications, ensuring complete compliance with IBC standards.
Condensation control on chilled water pipes and duct systems directly impacts indoor air quality. High-density open and closed-cell elastomer options minimize breakout noise and structure-borne vibration in massive industrial air handler units and high-capacity central chillers.
Architects across North America use sound absorption technology to gain LEED points. Mitigating noise pollution in commercial spaces while maintaining thermal resistance (R-value) targets reduces operational carbon profiles and supports building longevity.
Our reputation is built on repeatable engineering. Every batch of Kingflex sound absorption and thermal pipe wrap undergoes strict testing parameters, ensuring compliance with international industrial benchmarks.
Kingflex standard dimensions utilize advanced NBR/PVC polymer formulations that achieve closed-cell structures exceeding 98%. Under rigorous testing, our formulations demonstrate low moisture absorption, high compression resilience (>80%), and consistent long-term thermal conductivity down to cryogenic levels.
Our materials hold premium international approvals, including BS 476, CE, REACH, ROHS, UL94, and ASTM. Through systematic material traceabilities, every structural project in the USA receives detailed engineering guarantees from batch raw-material tests to production-line delivery.
Our manufacturing setups yield two distinct structural forms tailored to American architectural standards, ensuring clean mechanical integration and maximum physical performance.
Kingflex Standard Dimension:
Structural Advantages:
Our sheets foam evenly with a closed-cell rate exceeding 98%. The fully closed design acts as an integrated moisture vapor barrier, providing stable, long-term thermal conductivity while preventing mold growth and structure-borne vibration transmission.
Primary US Applications: Central air conditioning ducts, general commercial roof/wall dampening, industrial storage tank insulation, and transportation rail cabin noise mitigation.
Kingflex Standard Dimension:
Structural Advantages:
Our pipe systems utilize specialized extrusion equipment to ensure consistent wall thickness. These pre-formed elastomeric cylinders reduce installation time and virtually eliminate the risk of thermal bridging or pipe freezing under humid conditions.
Primary US Applications: Chilled and hot water piping, refrigeration lines, commercial HVAC plumbing systems, and steam/process lines in petrochemical facilities.
Our high-performance sound absorption and thermal barriers are designed for specific industrial environments across the United States.
In major hubs like New York City, Chicago, and Los Angeles, localized codes demand strict sound transmission class (STC) ratings between floors and adjacent mechanical rooms. Applying Kingflex closed-cell panels inside HVAC duct networks mitigates duct breakout noise, preventing low-frequency fan drone from disturbing living areas.
Along the US Gulf Coast (Texas and Louisiana), heavy chemical plants demand specialized insulation to prevent Corrosion Under Insulation (CUI). Kingflex ultra-low temperature cryogenic rubber foam is formulated to perform continuously down to -200°C, providing critical thermal barriers while managing high-intensity industrial pipe vibrations.
Acoustical comfort is critical in modern hospitals to support patient recovery. Using fiber-free, mold-resistant Kingflex open-cell elastomers for pipe insulation and duct linings satisfies both structural acoustic control requirements and strict indoor air quality (IAQ) regulations.
Our success is driven by our team's commitment to quality. Our technical engineers work directly with developers and project contractors to design and deliver high-performance acoustic solutions.
Established in 1979 by Jinwei Group, we became the first thermal insulation manufacturer north of the Yangtze River, building decades of engineering expertise.
Our team includes 8 professional R&D engineers, 6 international sales agents, and 230 manufacturing specialists operating five automated production lines.
We export to over sixty-six countries, providing high-quality thermal and acoustic insulation solutions to construction projects worldwide.
Our future product development balances high performance with environmental responsibility.
Kingflex continues to innovate in high-performance materials. Our upcoming range of eco-elastomers utilizes halogen-free formulations to exceed stringent California Proposition 65 requirements.
Our manufacturing updates include transitioning to carbon-neutral blowing agents, helping our products meet LEED V4 requirements for low VOC emissions while maintaining mechanical insulation performance.
In industrial acoustics, we are developing multi-layer composite barriers that integrate open-cell foam with viscoelastic polymer layers, achieving excellent Sound Transmission Loss (STL) properties for heavy machinery enclosures.
Our insulation materials are specified across major North American industrial centers and commercial developments.
We provided acoustic insulation sheet rolls to reduce mechanical vibration in air handling units for a commercial high-rise development in Houston.
We supplied cryogenic closed-cell NBR/PVC pipe wraps to manage low-frequency noise and prevent condensation in a regional chemical plant.
