Explore our elite series of high-density elastomeric foam rolls and tubes engineered for extreme temperature control and moisture management.
In modern industrial and commercial construction, thermal performance is no longer the sole metric of evaluation. Project designers, engineers, and HVAC specialists are placing critical importance on environmental credentials, visual categorization, and aesthetic alignment. The Green Color Rubber Foam Insulation Sheet Roll represents a major advance in this field. Traditionally, elastomeric nitrile rubber insulation (NBR/PVC) has been produced in black. However, colored foam serves a crucial operational purpose in high-density installations, signaling specialized HVAC/R cooling loops, ventilation routing, or environmental zones while ensuring premium thermal management.
As a leading global manufacturer, Kingflex Insulation Co., Ltd. has pioneered the formulation of colorful elastomeric matrices that do not compromise on fire ratings or moisture permeability. By utilizing clean, high-grade nitrile rubber and state-of-the-art curing systems, Kingflex ensures that the green insulation roll provides the exact same high-resistance closed-cell performance as its standard black counterparts, while aligning with modern green building standards and aesthetic demands.
The performance of Kingflex's Green Color Elastomeric Foam Sheet Roll lies in its micro-cellular chemistry. The material is formed using a precise blend of Nitrile Butadiene Rubber (NBR) and Polyvinyl Chloride (PVC), which undergo a highly controlled vulcanization and foaming process. This creates millions of independent micro-voids containing dry air. Because these pockets are independent and hermetically sealed, the transmission of both thermal energy and water vapor is heavily restricted.
By retaining stationary air inside a 98% closed-cell structure, the thermal conductivity remains exceptionally low: $\le 0.034$ W/(m·K) at 0°C. This restricts heat gain in chilled water lines and prevents heat dissipation in heating loops, reducing total HVAC energy consumption.
Unlike open-cell fibrous products like fiberglass or rock wool, Kingflex elastomeric foam acts as an integrated vapor barrier. With a moisture resistance coefficient exceeding 10,000, water cannot migrate through the insulation, avoiding the loss of thermal efficiency and preventing corrosion under insulation (CUI).

Kingflex's research and development department is located in Dacheng, China—historically celebrated as the capital of green-building materials. Sourcing from our massive modern facility provides global buyers with structural benefits that go beyond simple unit pricing:
For international procurement managers, importing insulation products involves strict fire safety codes, environmental standards, and chemical regulations. Kingflex addresses these requirements through a robust international certification matrix:
In the UK and Commonwealth countries, products must meet BS 476 Part 6 & 7 (Class 0 rating for flame propagation and surface spread of flame). In Europe, materials must carry the CE Mark and comply with strict REACH and RoHS regulations, which limit hazardous substances in construction materials. For projects in North America, products must align with ASTM standards and carry UL94 flammability ratings. Kingflex products have passed all these international tests, ensuring smooth customs clearance and local building inspection approvals.
Furthermore, batch traceability is integrated into our quality control system. Every roll that leaves our plant is marked, ensuring that technical parameters, production dates, and raw material runs are fully transparent and accessible to project inspectors on-site.
The application of Green Color Rubber Foam Sheet Rolls goes beyond general thermal protection. Here are the specialized areas where this product is highly valued:
In complex commercial structures (like data centers, airports, and hospitals), pipes must be color-coded for safety and quick maintenance. Green foam provides instant visual identification for clean air lines, cold water supply, or environmentally friendly cooling loops without the need for post-insulation painting or wrapping.
Modern commercial buildings (such as offices, retail spaces, and creative parks) often leave mechanical ductwork exposed. The bright green elastomeric foam adds a sleek, high-tech industrial aesthetic to these interiors while providing excellent thermal insulation and acoustic dampening.
HVAC blowers and airflow within metal ducts produce high-frequency vibration and structural noise. The dense, elastomeric structure of our green foam absorbs acoustic energy, preventing noise transmission through ceilings and walls in hotels, multi-family residences, and recording studios.
Chemical processing and storage environments expose piping to extreme temperatures and corrosive substances. Sourced green elastomeric sheets offer physical protection, resist chemical degradation, and reduce the risk of structural failure due to freeze-thaw cycles.
