Kingflex
In the modern construction and industrial manufacturing landscapes, performance criteria for insulation materials have expanded beyond simple thermal efficiency. Today, global regulatory standards like LEED, BREEAM, and various international decarbonization goals require materials that offer high-level insulation, prevent condensation, and visibly showcase their green, eco-friendly footprint. The Green Color Rubber Foam Insulation Sheet Roll represents the pinnacle of this development, combining the proven performance of NBR/PVC elastomer formulations with distinct color identification suitable for complex HVAC, cleanroom, and industrial mechanical setups.
Unlike traditional black elastomeric foam, the green coloring serves a functional dual purpose: it acts as a visual guide for specific piping systems (such as supply/return air lines, cold water pipes, or specific industrial processes) and highlights the project's adherence to green building materials standards. Formulated in Dacheng, China—known globally as the capital of green-building materials—our green insulation rolls utilize advanced foaming technologies that keep environmental impact low while delivering stable, long-term technical results.
Information Gain Note: Green elastomeric foam insulation is not merely a color variant. By incorporating halogen-free components and low-VOC emissions characteristics, it meets stringent indoor air quality audits. Facility managers can easily audit cleanrooms and complex machinery rooms when color-coded materials are implemented.
Established by the Jinwei Group, which boasts a history of more than 40 years since its inception in 1979, Kingflex Insulation Co., Ltd. is a leading professional manufacturing and trading combo. Jinwei Group was the first manufacturer of thermal insulation materials north of the Yangtze River, paving the way for advanced elastomeric research in East Asia.
Operating with energy conservation and consumption reduction as core concepts, Kingflex provides holistic solutions regarding insulation by means of consulting, research and development, custom production, installation guidance, and dedicated post-sale services.
Currently, our facility operates 5 large automatic assembly lines, generating an annual production capacity exceeding 600,000 cubic meters. Our technological standards have earned us designation as a production enterprise for the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry.
Innovation is driven by our R&D Department, staffed by 8 professional engineers, alongside 6 international sales representatives and 230 highly trained factory personnel. Our research department utilizes modern laboratories to analyze raw material purity, cell structure density, and chemical safety, ensuring the production of high-performance closed-cell elastomeric structures.
Our green rubber foam insulation products have been systematically exported to over 66 foreign countries worldwide, satisfying strict structural codes and energy conservation policies across Europe, North America, Southeast Asia, and the Middle East.
Understanding the physics of closed-cell elastomeric foam is key to determining its performance in the field. Our NBR/PVC matrix consists of thousands of independent micro-cells that trap air, restricting heat transfer and moisture migration. Below is the technical performance profile of our standard elastomeric insulation sheet rolls:
| Property Parameter | NBR/PVC Elastomeric Foam Sheet Value | Testing Standards & Methods |
|---|---|---|
| Thermal Conductivity (λ) | ≤ 0.034 W/(m·K) at 0°C | ≤ 0.038 W/(m·K) at 40°C | ASTM C518 / ISO 8301 |
| Water Vapor Diffusion Resistance (μ) | ≥ 10,000 (Prevents moisture ingress completely) | BS EN 12086 / ASTM E96 |
| Density Range | 40 - 55 kg/m³ | ASTM D1622 |
| Service Temperature Range | -40°C to +105°C (Special cryogenic series down to -200°C) | ASTM C411 |
| Fire Classification | Class 0 / Class 1 / UL 94 V-0 / ASTM E84 (25/50) | BS 476 Part 6/7, UL94, ASTM E84 |
| Compression Resilience Rate | Over 80% (Exceptional recovery from mechanical load) | ASTM D1667 |
| Acoustic Attenuation | Up to 32 dB noise reduction (Structure-borne sound) | ISO 10140 |
Global supply chains are placing higher demands on component transparency, fire safety, and environmental impact. Heavy industries, mechanical engineering firms, and HVAC systems builders are shifting away from general-purpose materials toward specialized elastomeric compounds. Large-scale procurement teams face the challenge of sourcing materials that satisfy local green building codes while keeping costs within project parameters.
At Kingflex, we address these demands by maintaining a direct-to-factory pricelist structure that reflects commodity raw materials costs (primarily NBR and PVC) while ensuring consistent chemical formulations. This transparency protects commercial developers from market price swings and ensures quality compliance for long-term construction projects.
For international procurement agents, tracing chemical compositions is essential. Our green rubber foam sheet rolls comply with REACH and RoHS regulations, verifying they are free from heavy metals, PBDEs, and volatile organic solvents. In high-density settings like data centers, high-rise buildings, and marine transport vessels, this chemical purity prevents toxic fumes in the event of a fire.
Modern mechanical systems operate across a wide range of temperatures and environmental conditions. Our design engineering division has developed distinct application pathways to match these diverse needs:
At temperatures reaching down to -200°C, traditional insulation can crack due to thermal contraction. Kingflex cryogenic systems use elastomeric configurations to prevent cracking, stop moisture vapor ingress, and minimize heat gain in industrial liquid gas operations.
Managing condensation on chilled water pipes and air conditioning ducts is critical to preventing mold growth and building structure damage. Our green rubber foam sheets offer a high resistance factor (μ > 10,000) that keeps humidity out, ensuring dry, clean, and efficient HVAC operation.
For mechanical rooms, manufacturing floors, and commercial air plenums, sound insulation is essential. The elastomeric cell matrix dampens high-frequency vibrations and controls structural noise, creating comfortable, compliant working spaces.
Our commitment to manufacturing quality is backed by comprehensive certifications from leading testing authorities. Every sheet roll is fully traceable to the raw material batch.
International Verification: Kingflex green rubber foam sheet rolls have passed BS 476, CE, REACH, RoHS, UL94, and ASTM certifications. This verified safety portfolio makes the material suitable for direct installation in public projects, infrastructure developments, and critical HVAC designs globally.
Our insulation solutions protect pipelines, industrial systems, and commercial properties globally. Check out some of our visual case studies:
While the performance profiles are similar, our production guidelines distinguish these materials to optimize project installations. Both products offer high density, low thermal conductivity, and standard dimensions built to withstand demanding conditions:
Standard formulation for general mechanical insulation. Great for hidden air plenums, underground utilities, and central HVAC ducts.
High-performance, color-coded formulation. Ideal for microelectronics facilities, pharmaceutical cleanrooms, and exposed installations requiring simple visual inspection.
Clear communication and reliable dispatch processes form the foundation of our trading combo. We maintain real-time order tracking and constant coordination with global clients.
We prioritize transparency and project support from first inquiry to port delivery. Our customer service team handles order updates, technical validation, and customized dimensions for large projects.
To guarantee product traceability, each shipping container is marked with manufacturing lot numbers, thermal testing certifications, and safety data sheets (SDS). This makes it easy for project inspectors to verify compliance on the job site.
Our NBR/PVC elastomeric foam is configured for various industrial components, piping systems, and building assemblies.
The demand for sustainable construction materials is steering the insulation industry toward cleaner chemistry. Kingflex R&D is focused on creating next-generation elastomeric foams that reduce carbon footprints without sacrificing safety or performance:
Our future product lines will feature environmental product declarations (EPDs) and health product declarations (HPDs). This technical transparency helps global building designers earn higher ratings under LEED v4.1 and BREEAM systems, easing project approvals in regulated markets.
