Kingflex
Select from our internationally certified line of thermal and acoustic insulation materials designed for copper piping and cryogenic infrastructure.
How Kingflex shapes the future of thermal insulation through chemistry and microstructural engineering.
By optimizing the NBR/PVC matrix at a molecular level, our R&D department has successfully elevated the closed-cell ratio to exceed 98%. This high-density gas-retention structure limits the movement of thermal molecules, keeping long-term thermal conductivity stable.
Safety is paramount. Our modern formulation integrates non-halogenated flame retardants that comply with BS 476 and UL94 Class 0 standards. Under fire stress, the material carbonizes to form a protective layer that stops flames from spreading, producing minimal smoke density.
Our material features an built-in vapor barrier with a very high moisture resistance factor (μ-value). By eliminating the need for external wraps on copper pipe networks, it prevents water vapor from penetrating, protecting pipelines from corrosion under insulation (CUI).
Kingflex Insulation Co., Ltd. is located in Dacheng, China—a well-known capital for green building materials. Backed by the Jinwei Group, which brings over 40 years of manufacturing experience (founded in 1979), we have grown to become a leading thermal insulation manufacturer in northern China.
Today, our facility runs 5 large automatic assembly lines, generating an annual output of over 600,000 cubic meters. This immense scale allows us to support large-scale commercial developments, public HVAC infrastructure, and complex chemical piping systems without delivery delays.
We are a designated production enterprise certified by the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry in China. All production batches undergo automated inspection and are given unique identifiers for full traceability—ensuring consistent, high-quality materials reach your job site.
Tailored insulation engineering designed to withstand harsh temperatures and meet strict international compliance standards.
Designed for central air conditioning chilled/hot water pipes, condensate lines, and ventilation ducts. It stops condensation, prevents dripping damage to ceilings, and limits thermal loss in commercial buildings, hotels, and hospitals.
For demanding LNG systems and ultra-low temperature chemical lines. Engineered to prevent structural cracking at low temperatures and maintain insulation performance in extreme, sub-zero environments.
Corrosion-resistant elastomeric materials designed for power plants, oil refineries, and steam transfer lines. Provides thermal efficiency, dampens noise, and protects copper and steel pipelines from corrosion.

Equipped with thermal conductivity testing machines, aging ovens, smoke density measurement chambers, and compression testing units, our testing team guarantees that every delivery meets your mechanical specifications before leaving our warehouse.
Over the last 16 years, we have exported our custom rubber foam sheet and piping products to over 66 countries. Our logistics team handles shipping documentation, freight forwarding, and local compliance requirements, making your international procurement straightforward.
Key considerations for EPC contractors, engineering networks, and industrial wholesalers sourcing copper pipe insulation.
While low-quality open-cell foam is cheaper initially, it risks degradation from moisture penetration. Investing in Kingflex elastomeric closed-cell foam provides a 10-15 year service life, protecting copper lines from corrosion and energy loss.
For high-spec HVAC systems, tracking installation materials is crucial. Kingflex provides digital and physical batch tracking systems, allowing procurement managers to verify batch tests, density profiles, and fire-safety certificates.
Standard piping parameters don't always fit. Kingflex supports comprehensive OEM services, fabricating custom wall thicknesses (from 6mm up to 50mm) and inner diameters to match unique project requirements.
We pride ourselves on offering first-class service to our clients. Our dedicated support team consists of 8 professional engineers in R&D and 6 international sales managers, working together to keep projects running smoothly.
From advising on standard thicknesses to guiding installations on site, we help secure energy-efficient systems for architectural and industrial projects worldwide.
Kingflex insulation materials are trusted in real-world commercial, industrial, and civil infrastructure projects worldwide.
