Explore SpecsKenya is undergoing a rapid industrial transformation. Under the government's development blueprints, sectors such as food processing, petrochemical logistics, energy generation, and healthcare are expanding at unprecedented rates. Key strategic developments, including the expansion of the Mombasa Port LNG facilities, the build-out of cold chain logistics corridors along the Standard Gauge Railway (SGR), and the scaling of biomedical cold storage hubs in Nairobi, have dramatically increased local demand for high-performance cryogenic insulation products.
In tropical climates like Kenya's, where high ambient relative humidity and elevated temperatures are standard, conventional open-cell insulation materials fail quickly. Moisture penetration causes rapid deterioration, dramatically increasing thermal conductivity ($\lambda$) and driving system energy losses up. This is where advanced NBR/PVC closed-cell technology plays a critical role, providing an integrated water vapor barrier that resists moisture ingress indefinitely and maintains process temperature control down to -200°C.
Designed to deliver optimal thermal properties, structural flexibility, and moisture resistance under rigorous working conditions.
Our cryogenic insulation solutions leverage a highly cross-linked NBR/PVC elastomeric structure. Below are the core technical specifications and dimensional guides for both Black Rubber Foam Insulation Sheet Rolls and Black Rubber Foam Insulation Pipes.

Founded by the Jinwei Group, which brings over 40 years of industry experience since its establishment in 1979, Kingflex is a pioneer in green thermal materials. As the first major manufacturer of modern thermal insulation north of the Yangtze River, we have built a reputation for high manufacturing standards and reliable performance.
Today, Kingflex operates as a unified manufacturing and trading hub, providing end-to-end support from initial design consultation to post-sale installation guidance. Our R&D department features 8 specialized engineers, supported by 6 international sales consultants and a production team of 230 workers, ensuring quality and technical support for every project.
Our on-site laboratories run regular tests for heat transfer, fire rating, smoke emission, and aging resistance, ensuring long service life for all products.
All Kingflex products are certified under BS 476, CE, REACH, RoHS, UL94, and ASTM, providing the quality assurance needed for commercial and industrial bids.
Exporting to 66+ countries, we manage logistics smoothly from our facility to the Port of Mombasa, ensuring clear customs handling and secure transit.
In low-temperature and cryogenic applications, controlling humidity and vapor pressure is a primary challenge. When the surface temperature of piping drops below the ambient dew point, moisture naturally condenses on the pipe. If the insulation material is permeable, water vapor will penetrate, freeze inside the insulation, and compromise the entire thermal system.
Our NBR/PVC closed-cell structure is designed to address this issue by providing two core lines of defense:
| Thermal Challenge | Potential System Risk | Closed-Cell Elastomeric Solution |
|---|---|---|
| Vapor Pressure Differential | Moisture ingress, freezing, loss of thermal efficiency | High μ factor (≥10,000) prevents water vapor from entering the material. |
| Extreme Cold Stress | Brittle cracking of polymers at temperatures below -40°C | Modified elastomeric blend maintains flexibility and integrity down to cryogenic levels. |
| Corrosion Under Insulation (CUI) | Acidic water pooling on metal pipes, causing structural failure | Impermeable material structure prevents moisture pooling on the pipe surface. |
| Flammability Hazards | Flame spread through utility shafts and pipe chases | Class 1 / Class 0 fire ratings ensure the material is self-extinguishing in fire conditions. |
