Kingflex
Engineered thermal systems designed to maximize thermal efficiency, suppress noise transmission, and prevent moisture condensation across industrial, commercial, and cryogenic applications.
Exploring the molecular configuration and structural physics that make Kingflex NBR/PVC insulation the standard for critical thermal defense.
Our elastomeric insulation features an optimized cell configuration with a closed-cell rate exceeding 98%. Each microscopic pocket of air is completely sealed off from neighboring units, forming a continuous gaseous matrix that suppresses thermal transfer via convection.
This closed matrix inherently resists mechanical deformation and prevents the capillary absorption of moisture, ensuring the design parameters remain stable over decades.
When moist air contacts cold surfaces, condensation forms, leading to corrosion under insulation (CUI). Kingflex's rubber foam possesses a high resistance factor to water vapor dispersion (high Mu value).
With built-in moisture barriers distributed evenly throughout the entire thickness, there is no need for external protective wraps or vapor jackets under typical design conditions.
Safety is critical. Our proprietary compound blending integrates flame-retardant elements that enable self-extinguishing behavior. The composite carbon layer formed during fire exposure halts flame propagation, lowering toxic smoke emissions.
Fully certified under stringent international safety frameworks, ensuring building safety compliance.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Our research, development, and main production facility is situated in Dacheng, China—historically recognized as the capital of green-building materials.
As an energy-saving, environmentally friendly enterprise, we concentrate on the research, development, production, sales, and implementation of high-performance elastomers. In operation, Kingflex takes energy saving and consumption reduction as the core concept.
We provide comprehensive solutions regarding insulation by means of expert consultation, research and development production, installation guidance, and post-sale service to lead the development of the global building materials industry.
Kingflex was established by the Jinwei Group, which boasts more than 40 years of corporate history. Established in 1979, the Jinwei Group was the first manufacturer of thermal insulation materials north of the Yangtze River, paving the way for decades of industrial excellence.
At present, Kingflex has 5 large automatic assembly lines, with an annual production capacity of more than 600,000 cubic meters. Our technical capabilities and supply chain reliability have made us a designated production enterprise designated by the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry.
Our R&D department features sophisticated diagnostic and testing tools to ensure consistent quality. Our team consists of highly skilled personnel working in harmony: 8 professional engineers in the R&D Department, 6 professional international sales managers, and 230 dedicated workers in our production department.
This tight-knit, talented group shares a unified vision of delivering consistently first-class service for our clients, ensuring that every batch of material produced complies with global standards.
Optimizing thermal defense across challenging industrial systems, public infrastructure, and heavy commercial developments.
Our solutions prevent condensation on chilled water pipes and ductwork, improving indoor air quality (IAQ) by avoiding mold growth. The flexible elastomeric foam dampens mechanical vibrations and structural noise, making it ideal for schools, hospitals, and office complexes.
In power plants, chemical plants, and heavy manufacturing units, Kingflex supplies thermal defense for high-temperature and cold process lines. The closed-cell structure helps control thermal drift, reducing fuel consumption and operational costs.
For cryogenic applications down to -200°C (including LNG transport, liquid oxygen processing, and cold chain distribution centers), our multi-layered cryogenic rubber foam systems remain flexible, preventing stress cracking and thermal contraction failure.

Our commitment to quality control is verified by third-party testing laboratories. Kingflex insulation systems have successfully passed testing to receive certifications including:
This strict level of testing ensures that our products are ready for installation in chemical, municipal, residential, and defense applications globally.
As global environmental policies shift towards carbon neutrality, the insulation industry faces new challenges. Kingflex is committed to developing sustainable, long-term technical solutions:
1. Carbon-Neutral Raw Materials: Our lab is testing bio-based elastomers and natural plasticizers to reduce reliance on petroleum products while maintaining fire safety ratings.
2. Halogen-Free Materials: To meet strict indoor air quality (IAQ) and rail transit specifications, we are scaling production of halogen-free flame-retardant (HFFR) elastomeric foams that produce lower smoke density and toxic gas levels.
3. Integrated Vapor Jackets: Our upcoming product lines feature factory-applied aluminum protective coatings and self-adhesive backings, reducing installation labor costs on-site.
Transparent communication and strict quality control for projects in over 66 countries.
We provide complete traceability on all shipped orders, allowing engineers to track material batches back to raw material input. Dedicated sales managers provide quick assistance to engineers and purchasing departments worldwide.
Providing reliable performance across complex construction and industrial projects.
