Kingflex
Explore our top-tier certified open-cell, closed-cell, and ultra-low temperature cryogenic structural isolation products designed for critical system installations.
In modern architectural design, the demand for noise mitigation is soaring. Environmental consciousness, coupled with regulatory compliance, has accelerated the adoption of natural cellular structures—specifically cork board sound absorption systems—alongside synthetic high-density elastomeric foams.
"Natural cork is structured with millions of microscopic, air-filled honeycomb cells. When sound waves hit this interface, the acoustic energy is trapped and converted into heat through frictional resistance within the micro-chambers, delivering a remarkably high Noise Reduction Coefficient (NRC)."
Leading structural energy-saving, environmental protection, and noise reduction research development under the legendary Jinwei Group.
Established by the Jinwei Group, which boasts over 40 years of structural engineering history. Kingway Group (founded in 1979) was the pioneer manufacturer of thermal insulation materials north of the Yangtze River, creating a benchmark of premium engineering quality.
We foster a highly integrated culture where 8 professional research and development engineers, 6 international customer support executives, and 230 specialized production workers build solutions designed to perform under demanding conditions.
Kingflex is committed to supplying comprehensive, integrated solutions for HVAC systems, cryogenic pipelines, commercial offices, building envelopes, and sound transmission mitigation, minimizing global carbon emissions.
Located in Dacheng, China, our advanced research and production site utilizes state-of-the-art automation. By controlling the exact density, cell distribution, and foaming speed of elastomeric and sound-absorption composites, Kingflex delivers consistency that international standard projects demand.
How our smart manufacturing lines benefit global distributors, procurement managers, and MEP contractors.
Our five main automated assembly lines strictly control key operational variables like pressure and curing temperature. This yields an exceptionally high closed-cell rate (over 98%), ensuring stable thermal conductivity and sound absorption capabilities.
We support precise tailoring of products. From 6mm to 50mm thickness for sheet rolls, and customized density configurations (40-55 kg/m³) or ID sizes, our engineering department designs insulation tailored for unique installations.
Each batch of Kingflex elastomeric and sound-insulation board products is cataloged, ensuring raw materials are tracked from arrival through production, quality control testing, packaging, and ultimate dispatch.
| Product Type | Standard Dimensions / ID | Thickness Range | Density | Service Temperature Range |
|---|---|---|---|---|
| Black Rubber Foam Insulation Sheet Roll | Custom rolls | 6mm - 50mm | 40 - 55 kg/m³ | -40℃ to 105℃ |
| Black Rubber Foam Insulation Pipe | ID: 6mm - 114mm | 9mm - 40mm | 40 - 55 kg/m³ | -40℃ to 105℃ |
We believe in absolute safety, verified testing, and compliant product design. Our products conform to key global structural, fire safety, and hazard standards.
Kingflex insulation boards and pipes hold certifications from leading global verification bodies, ensuring trouble-free project approvals.
From freezing petrochemical conduits to soundproofing high-traffic commercial buildings, discover where Kingflex insulation is utilized.
Perfect for ductwork lining and water pipe systems. By dampening vibration noises (such as turbulent airflow) and preventing moisture condensation, our sheets and pipe insulation are widely deployed in commercial hotels, office buildings, and hospitals.
Specially formulated for cryogenic systems and pipelines down to -40℃. Prevents energy loss, limits pipe cracking risks, and resists chemical corrosion in petrochemical and marine shipping industries.
For recording studios, classrooms, and boardrooms, combining cork board acoustic panels with open-cell elastomeric rubber creates a barrier that eliminates echo, reduces transmission loss, and ensures structural acoustics.
Over 16 years of supply history powering infrastructure, manufacturing, and heavy industry plants across 66 countries.
