Engineered for maximum thermal resistance, structural integrity, and exceptional resistance to flame spread.
The industrial thermodynamic landscapes are transitioning at an unprecedented speed. With global initiatives pointing toward clean energy and operational efficiency, traditional open-celled or low-density insulation technologies are falling short. Standard elastomeric foams often face thermal degradation and loss of structure when operating continuously beyond conventional thresholds. Today, the industrial market dictates the integration of next-generation High Temperature Foam polymers capable of maintaining structural stability, high closed-cell ratios, and minimal water permeation at extremes ranging from cryogenic values up to elevated temperatures.
In petrochemical facilities, heavy-industry manufacturing, complex HVAC configurations, and aerospace infrastructure, the choice of a protective barrier directly correlates to long-term lifecycle savings and asset protection. High-temperature elastomeric formulations—predominantly reinforced with NBR/PVC matrices, EPDM upgrades, or proprietary alkadiene rubber variants—combat typical degradation pathways: thermal oxidation, moisture intrusion, and chemical corrosion under insulation (CUI).
Global insulation procurement officers face structural hurdles: balancing initial raw materials pricing against performance properties, global compliance standards, and lead-time constraints. Purchasing departments operating across the Americas, EMEA, and Asia-Pacific must prioritize manufacturers possessing fully integrated testing capabilities and traceable supply lines.
When selecting a high-temperature foam partner in China, target factories must demonstrate deep adherence to recognized standards including:
Kingflex Insulation Co., Ltd. stands as a premier manufacturing and trading powerhouse specializing in elite thermal and cryogenic insulation products. Strategically headquartered within Dacheng, China—historically celebrated as the national capital of green-building materials—we are a dedicated energy-saving enterprise focusing on advanced engineering, production, and worldwide sales pipelines.
We are a direct subsidiary of the prestigious Jinwei Group (Kingway Group), which traces its legacy back to 1979. As the pioneer manufacturer of thermal insulation materials north of the Yangtze River, our heritage is built on decades of empirical testing and engineering iterations. Today, Kingflex drives the market forward, transforming traditional raw materials into smart energy-saving systems.
NBR/PVC elastomeric foams developed in our state-of-the-art Dacheng complex are engineered to resolve major insulation failures such as water absorption and flame penetration. Below is an overview of the key thermal and structural parameters of our core product line:
| Physical Property | Standard Value / Limit | Standard Test Reference |
|---|---|---|
| Material Composition | Premium Acrylonitrile Butadiene / Polyvinyl Chloride (NBR/PVC) | Internal Quality Dossier |
| Density Range | 40 - 55 kg/m³ | ASTM D1622 |
| Service Temperature Limit | -40℃ to 105℃ (Special Cryogenic variants down to -196℃) | ASTM C534 |
| Thermal Conductivity (λ) | ≤ 0.034 W/(m·K) at 0℃ | ASTM C177 / C518 |
| Closed Cell Structure Rate | ≥ 98% | ASTM D2856 |
| Moisture Resistance Factor (μ) | ≥ 10,000 | BS EN 12086 |
| Flammability Standards | BS 476 Part 7 Class 0/Class 1, UL94 V-0, ASTM E84 Class A | Intertek / SGS Certified |
The high closed-cell configuration prevents the moisture path from penetrating the outer surface, rendering extra vapor barriers obsolete in typical conditions. Under cycles of temperature shifts, typical open-cell structures collect moisture, driving rapid drop-offs in insulation capacity. Our foams maintain static λ values over long lifecycles (typically 10 to 15 years in rugged conditions).
Key Advantages: High elasticity, uniform microscopic cells, superior compression resilience (≥ 80%), and flame-retardant self-extinguishing behavior. Ideal for massive flat layouts, industrial chambers, and HVAC duct wrap.
Key Advantages: High tensile strength, seamless extrusion, and easy slippage over standard pipeline diameters. Drastically minimizes risk of freezing, condensation, and corrosion in processing lines.
Kingflex materials are optimized for industrial environments demanding stable thermodynamic barriers. Our solutions are deployed across three critical fields:
Applied as duct wrap and piping insulation inside multi-story malls, hospitals, transport hubs, and residential compounds. Our insulation limits thermodynamic leaks, maintains internal air temperature, and attenuates machine room noise.
Withstanding cyclic temperatures, atmospheric ozone attacks, and hydrocarbon pollutants, our insulation boards defend chemical pipelines against degradation, preventing catastrophic heat exchange loss.
Our specialized flexible cryogenic series maintains elasticity at deep-freeze ranges (down to -196℃). This allows applications in liquid nitrogen systems, LNG processing terminals, and specialized medical cold storage chambers.
"Optimized insulation thickness prevents condensation in cooling lines and limits thermodynamic transfer in high-temperature lines, ensuring processing systems operate reliably."

As standard regulatory frameworks enforce zero-carbon requirements on structural materials, Kingflex is adapting its formulation development. Our technical roadmap aims to lower chemical footprints while enhancing fire resistance:
Transitioning standard foaming agents to high-stability, zero Ozone Depletion Potential (ODP) and zero Global Warming Potential (GWP) alternatives. This maintains strict environmental compliance for large-scale LEED civil projects.
Developing ultra-low density, high-temperature composite aerogel foams. Incorporating silica aerogels into the elastomeric matrix drops the thermal conductivity coefficient to below 0.028 W/(m·K), reducing insulation thickness by 30%.
Deploying visual inspection cameras and digital tracking software across all 5 automatic lines. Real-time scanning maintains thickness precision within ±0.5mm, ensuring consistent structural performance across large shipments.
We work directly with engineering partners globally. We support customized dimensions, specific flammability specifications, and provide project consulting services.
Our support team maintains active communication channels, coordinating project needs, delivery dates, and custom sizes with global engineers to ensure smooth project installation.
