Explore our leading industrial elastomer and cryogenic foam systems engineered for extreme environments.
Optimizing thermal management across municipal construction, chemical pipelines, and critical processes.
Condensation on structural metal pipelines remains a primary driver of system decay and indoor air degradation. Our closed-cell rubber foam solutions guarantee long-term control of moisture permeation, reducing localized HVAC load requirements and minimizing long-term infrastructure operating costs.
Moving fluids and chemical compounds requires extreme temperature stability to prevent material crystallization or unwanted vaporization. Utilizing high-density NBR/PVC elastomeric formulations protects process control margins across harsh operating conditions from -40°C up to 105°C.
LNG (Liquefied Natural Gas) distribution systems demand specialized low-temperature barriers that resist cracking under cryogenic shock. Our flexible cryogenic layers are systematically tested to ensure durability and thermal efficiency in extremely cold working environments.
Direct specifications from the production line, built to withstand challenging structural environments.
Engineered for expansive surface areas such as square ducts, massive tanks, and industrial piping manifolds. Our closed-cell rubber sheet offers a robust barrier against moisture and acoustic pollution.

Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Our research, development, and primary production facilities are located in Dacheng, China—a well-known capital of green building materials. As an energy-saving, environmentally friendly enterprise, we concentrate on the research and development, production, and sale of advanced insulation materials.
In operation, Kingflex takes energy saving and consumption reduction as its core concept. We provide insulation solutions through consulting, research and development, production, installation guidance, and post-sale service to lead the development of the global building materials industry.
Established by the Jinwei Group, which has more than 40 years of history (established in 1979), Kingflex inherits a strong legacy. Jinwei Group was the first manufacturer of thermal insulation materials north of the Yangtze River, paving the way for decades of technological expertise.
At present, Kingflex operates 5 large automatic assembly lines, generating an annual production capacity of more than 600,000 cubic meters. Our strict adherence to state standards has made us a designated production enterprise for key departments, including the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry.
Our products are widely utilized in construction, petroleum, chemical processing, national defense, and aerospace projects. Over the past 16 years, Kingflex thermal insulation products have been exported to more than 66 countries worldwide, offering consistent quality across diverse regional climates.
How our engineering team develops next-generation thermal barriers that comply with international safety regulations.
Our dedicated R&D department, led by 8 professional engineers, focuses on modifying polymer structures to lower thermal conductivity ($\lambda$) under high mechanical stress. By optimizing the NBR/PVC ratio, our materials maintain structural flexibility and resist tearing, even during complex field installations.
To support this development, we operate internal labs that simulate extreme temperature changes, moisture absorption cycles, and flame exposure. This testing ensures that our products perform reliably in real-world conditions.
To supply demanding international projects, our products meet a range of global safety and environmental requirements. Kingflex insulation has been certified to meet the following industry standards:
Our employees bring diverse skills that together drive Kingflex's growth. Our team is a tight-knit, talented group focused on providing consistent, high-quality service for our clients.
Kingflex has 8 professional engineers in our R&D department, 6 international sales specialists, and 230 skilled production workers who keep our factory lines running efficiently.
Our customer support team assists clients throughout the procurement process, offering support from initial configuration and customized profiling to final logistics delivery.
We work closely with global engineering clients to ensure product performance matches project specifications. These screenshots from client chats highlight our regular communication regarding project milestones, quality verification, and shipping arrangements.
Whether you require standard dimensions or customized profiles, our technical sales team helps ensure products match your local insulation standards.
Understanding raw material factors, bulk volume tiers, and global shipping variables.
Our pricing corresponds with fluctuations in quality nitrile butadiene rubber (NBR) and polyvinyl chloride (PVC) indexes. Adding custom fire retardants, UV stabilizers, or external aluminum foil facing alters material configurations and overall system costs.
We operate on scaled price structures: ordering full container loads (FCL) allows for lower unit costs per cubic meter by maximizing extrusion runs and reducing packaging material waste.
We provide standard PE protective wrapping alongside premium options, such as reinforced fiberglass skins, heavy-duty alu-foils, or self-adhesive backings for fast installation.
Technical answers regarding product installation, material performance, and factory capabilities.
Elastomeric rubber foam insulation is mainly used for HVAC ducts, air conditioning pipes, building thermal insulation, industrial pipeline cold insulation, and sound insulation. Its closed-cell structure prevents moisture condensation and blocks energy loss on metal surfaces.
Yes, our rubber foam insulation is formulated to be fire retardant. It complies with major safety standards like BS 476 and UL94, ensuring it is suitable for commercial building and industrial projects.
Rubber foam is flexible, closed-cell, and moisture-proof, making it suitable for HVAC, chilled water pipes, and general building insulation. It does not require a separate vapor barrier.
Rock wool is highly temperature-resistant and fireproof, making it ideal for high-temperature industrial steam lines, furnace systems, and chimneys.
Yes, we support OEM and custom services. We can adjust the thickness, inner diameter, densities, and outer coatings (such as aluminum facing or self-adhesive layers) to meet specific project needs.
Our products have passed BS 476, CE, REACH, RoHS, UL94, and ASTM testing. These certifications ensure our products meet international quality and environmental safety standards.
Yes, every production batch has a unique batch code. This allows us to track raw materials, production line conditions, and quality control tests for each order.
