Deep insight into mechanical properties, condensation control physics, and thermal retention optimization.
When operating chilled water lines, glycol chillers, or cold refrigeration loops, the primary threat is condensation. If the warm ambient air touches a pipe surface cooler than the dew point, water vapor liquefies, causing mold growth, structural damage, and severe pipe corrosion under insulation (CUI). A 25mm wall thickness provides structural resistance that keeps the outer insulation jacket temperature above the dew point, even under harsh operating environments (e.g., 35°C ambient temperature with 85% relative humidity).
A premier industry combo for manufacturing and trading advanced thermal and acoustic insulation materials.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Our core research, development, and production facility is located in Dacheng, China—widely recognized as the capital of green building materials. As an energy-saving and environmentally friendly enterprise, we integrate research, development, production, and sales. We utilize energy saving and consumption reduction as our core concept, delivering complete system solutions via pre-project consultation, bespoke R&D, expert installation guidance, and dedicated post-sale services, guiding the global building materials industry towards carbon neutrality.
Established by the prestigious Jinwei Group, which boasts over 40 years of manufacturing history since its founding in 1979, Kingflex stands as a legacy brand. Jinwei Group was the pioneer manufacturer of thermal insulation materials north of the Yangtze River, paving the way for advanced polymer foam research in Asia.
Our workforce is what makes Kingflex a top-tier global supplier. Our team is a tight-knit, talented group with a shared vision of providing consistently first-class service for our international clients. The Kingflex human resource architecture includes:
Leveraging high production capacity, automated processes, and strategic location logistics.
We operate 5 high-speed automated extrusion and vulcanization production lines. These systems guarantee uniform foam cells, consistent wall thickness tolerances (within ±0.5mm for a 25mm profile), and rapid production turnaround.
With an annual capacity exceeding 600,000 cubic meters, we are a designated manufacturer authorized by the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry.
Over the last 16 years, our high-performance thermal insulation solutions have been exported to more than 66 countries, adapting to diverse construction norms in Europe, the Americas, and Southeast Asia.
Our location in Dacheng gives us direct access to high-quality raw materials, including premium Nitrile Butadiene Rubber (NBR) and Polyvinyl Chloride (PVC) polymers. By sourcing raw materials locally and managing the polymer foaming process in-house, we eliminate intermediate supply chain markups, passing the savings to wholesale buyers and global distributors.

Standard Dimensions: Thickness from 9mm to 40mm, Inner Diameter (ID) options from 6mm up to 114mm, with a density of 40-55 kg/m³.
Key Advantages:
Primary Applications: Specifically engineered for commercial central air-conditioning lines, hot/cold domestic water pipelines, solar hot-water loops, and process pipe arrays in petrochemical plants.
Analyzing the evolution of market demands, sustainability regulations, and purchasing strategies.
Modern building codes, especially in Western Europe and North America, increasingly mandate halogen-free elastomeric foams. In a fire event, halogens release toxic gases. Kingflex halogen-free thermal insulation sheet rolls address this, ensuring low toxicity and low smoke generation (Class 0 compliance under BS 476).
As industries switch to liquefied gas storage (LNG) and deep chemical chilling processes, cryogenic pipelines require multi-layered rubber foam systems. The insulation must resist mechanical stress at ultra-low temperatures without cracking. Our cryogenic insulation sheets and tubes maintain flexibility down to -200°C, preventing stress fractures.
To further extend lifespan and prevent mechanical weathering, modern engineering designs require pre-clad solutions. Kingflex Aluminum foil-covered Rubber Foam Boards combine mechanical protection and thermal performance in one product, reducing field labor costs by up to 50%.
