Kingflex Insulation Co., Ltd. stands as a premier manufacturing and trading conglomerate dedicated to top-tier thermal and cryogenic insulation solutions. Strategically situated within Dacheng, China—historically celebrated as the national capital of energy-efficient green building materials—our operations are backed by the rich legacy of Jinwei Group, established in 1979 as the pioneering manufacturer of thermal insulation systems north of the Yangtze River.
As a key enterprise designated by the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry, Kingflex has evolved into a global leader. We integrate state-of-the-art research and development, smart manufacturing, global export, and hands-on installation support into a seamless system designed to reduce energy consumption worldwide.
Kingflex runs 5 fully automated assembly lines that operate continuously. Our scale of production allows us to meet large bulk requirements with short lead times, guaranteeing product consistency across batches. With an annual capacity exceeding 600,000 cubic meters, our facilities are built to handle the supply requirements of regional distributors, government utilities, and large infrastructure projects.
Our dedicated R&D center is equipped with advanced testing chambers to evaluate thermal conductivity, fire behavior under simulated flame exposure, smoke density, and moisture permeation rates. By testing raw materials through our molecular formulation lab, we ensure our NBR/PVC matrix remains resilient under severe structural stresses.
Our testing protocols verify the mechanical performance of our materials before dispatch. Every batch undergoes a series of QA checks:
This strict level of testing ensures that Kingflex insulation maintains its thermal barrier properties over its 10-to-15-year service life, helping prevent CUI (Corrosion Under Insulation) in moisture-prone industrial environments.
How Kingflex optimizes production, raw material access, and transport infrastructure to deliver reliable value to global markets.
Located in the Dacheng green materials cluster, we benefit from integrated upstream raw chemical supply lines. This limits domestic transit delays, protects us from raw material volatility, and helps stabilize unit costs for our partners.
Our automated extrusion and foaming lines run 24/7. By minimizing manual operations, we maintain tight control over dimensions, cell distribution, and foaming density while maximizing throughput.
With direct access to major maritime export channels (Tianjin/Tianjin Xin'gang Port), we expedite customs clearance, container packing, and global shipping to minimize transit times.
A detailed look at the physical properties of our primary NBR/PVC elastomeric product categories.
Key Mechanical Advantages: Low thermal conductivity combined with high moisture resistance prevents condensation on chilled water pipes and ductwork, protecting downstream structures from rot and corrosion.
Application Advantage: The inner diameter of our tubes is designed to fit snug against standard copper, steel, and plastic piping systems, simplifying installation and eliminating air gaps.
Kingflex insulation products are widely used in commercial construction, process plants, power grids, and deep cryogenic facilities. Below is a collection of site applications and shipping inspections from our global project files.
Every batch of Kingflex rubber foam is traceable and meets international quality and environmental standards.
For large industrial installations and commercial construction, meeting local building codes is essential. Kingflex products undergo third-party certification to ensure safety, durability, and reliable thermal performance under demanding conditions.
How Kingflex closed-cell rubber foam functions across major mechanical environments.
The Challenge: High atmospheric humidity can cause condensation on cold-water supply pipes and metal ductwork, risking water damage and mold growth.
The Solution: Kingflex sheets and tubes insulate the outer metal surfaces, preventing warm, humid air from contacting the cold pipes and eliminating condensation issues.
The Challenge: Systems operating at cryogenic temperatures down to -196℃ require stable insulation that won't crack or degrade under thermal contraction.
The Solution: Our specialty elastomeric line maintains its flexibility at sub-zero temperatures, forming a reliable vapor barrier that prevents frost buildup and thermal bridging.
The Challenge: Fluid flow and mechanical vibration in heavy piping systems can create airborne noise in office buildings, hotels, and marine vessels.
The Solution: Our high-density open/closed hybrid structures absorb sound energy, dampening mechanical vibrations and reducing structural noise transmission.
We work closely with global distributors and procurement managers, providing technical support, clear documentation, and prompt assistance throughout the ordering and delivery process.
"The consistency of the material thickness and cell structure across shipments has been excellent. Kingflex has helped us meet project schedules and quality requirements consistently."

A look at some of the projects and applications utilizing Kingflex insulation materials globally.
How regulatory updates and green building standards shape modern thermal barrier choices.
Global building standards like LEED and BREEAM have increased the focus on building materials with low VOC emissions. Standard elastomeric foams historically relied on chemical blowing agents that released VOCs over time.
Kingflex is developing advanced nitrogen-gas-blown formulations that eliminate halogenated flame retardants while maintaining fire safety ratings. This makes our materials suitable for high-density public spaces, hospitals, and green-certified buildings.
With the expansion of LNG terminals and low-temperature process engineering, the demand for reliable sub-zero insulation has grown. Traditional rigid systems can crack under thermal shock, leading to ice buildup and energy loss.
Kingflex cryogenic elastomeric foam uses modified nitrile polymers that remain flexible down to -196℃, accommodating pipeline movement without cracking or requiring expansion joints.
Below is our second selection of flexible insulation tubes, cryogenic barriers, and rock wool options for high-temperature applications.
