Engineered to prevent condensation and optimize energy efficiency in Vietnam’s high-temperature, high-humidity manufacturing hubs.
As Vietnam solidifies its position as a global manufacturing powerhouse—anchored by electronics hubs in Bac Ninh and industrial zones in Binh Duong and Hai Phong—the demands placed on building infrastructure have intensified. The region’s prevailing hot and humid tropical climate creates a constant temperature differential between chilled process lines and ambient air, making industrial facilities highly susceptible to surface condensation, mold growth, and excessive thermal loss.
Standard open-cell insulation materials fail to withstand the high relative humidity of Vietnam's wet seasons. Moisture ingress into insulation degrades its structural integrity and drives up thermal conductivity rapidly. To prevent this, global engineering procurement contractors (EPCs) working in Southeast Asia rely heavily on closed-cell elastomeric rubber foam sheets. These materials act as a built-in vapor barrier, ensuring long-term thermal performance even in harsh, unconditioned manufacturing environments.
While Vietnam's local manufacturing sector is growing, domestic thermal insulation output often faces raw material constraints and limited production scale. This is where partnering with a major Chinese manufacturer like Kingflex Insulation Co., Ltd. provides a significant competitive advantage for Vietnamese distributors and contractors.
Located in Dacheng, China—the capital of green building materials—Kingflex utilizes advanced, continuous manufacturing systems that operate at scales local factories cannot match. By blending raw nitrile rubber (NBR) and polyvinyl chloride (PVC) under strict laboratory conditions, Kingflex ensures uniform density and a closed-cell rate exceeding 98%. This high volume and consistent quality help developers in Hanoi, Da Nang, and Ho Chi Minh City secure top-tier elastomeric insulation materials on tight project schedules.

Closed-Cell Density Structure
Tailoring elastomeric systems for maximum performance in critical industrial applications.
Eliminates thermal bridging in central air conditioning systems. The flexible NBR sheet easily wraps rectangular and round duct systems, preventing external air condensation and dampening acoustic vibrations in commercial complexes and high-rise office towers.
Engineered to meet low-VOC and dust-free requirements. Essential for semiconductor, battery, and micro-component cleanrooms in Vietnam's high-tech parks, where micro-particles and chemical outgassing can ruin production yields.
Provides critical thermal protection for process pipes down to -40℃. The closed-cell matrix prevents moisture ingress, which can form internal ice layers that crack pipelines and compromise refrigeration efficiency.
Founded by the Jinwei Group, which has more than 40 years of industry experience since its establishment in 1979, Kingflex has grown into a leading manufacturer of thermal insulation materials. We operate 5 fully automated production lines with an annual output exceeding 600,000 cubic meters, making us a key supplier for major national and international infrastructure projects.
Our dedicated team includes 8 professional R&D engineers, 6 international sales experts, and 230 skilled production workers. By focusing on energy conservation and emission reduction, Kingflex delivers custom solutions that help engineers meet strict international building and fire codes.
A complete selection of elastomeric sheets, rolls, and pre-formed pipe insulations for regional project developers.
Every production batch undergoes strict quality control to guarantee compliance with global building and fire codes.
Kingflex elastomeric products are manufactured to meet high international performance standards. Our closed-cell rubber foam provides excellent moisture resistance and stable thermal conductivity, helping extend the operating life of commercial and industrial piping systems.

"For our high-humidity pharmaceutical packaging facility in Long An, Vietnam, maintaining strict indoor relative humidity was a key challenge. We selected Kingflex's 25mm closed-cell NBR foam rolls. They prevented surface condensation on our chilled water pipes and helped keep our energy footprint within budget. The project has been operating smoothly for over three years without any condensation issues."
