Advanced elastomeric foam structures engineered specifically for thermal barriers under severe Norwegian climate profiles
Norway is a global powerhouse in offshore energy, pioneering maritime transport, and carbon capture initiatives like the Northern Lights project. Operation in environments such as the Barents Sea and the North Sea demands thermal insulation materials that do more than prevent heat transfer. Systems must deliver absolute mitigation of Corrosion Under Insulation (CUI), maintain flexible structural integrity down to -200 °C, and withstand saline spray, heavy UV exposure, and mechanical vibrations.
Traditional open-cell insulation materials fail quickly in maritime conditions because they absorb atmospheric moisture, resulting in water vapor condensation, ice-lens formation, and accelerated pipe corrosion. Kingflex elastomeric closed-cell rubber foam addresses this challenge with a micro-cell structure that acts as an integrated vapor barrier. This ensures a constant, low thermal conductivity rating and helps protect critical cold-chain and LNG delivery infrastructures.
Founded by the Jinwei Group (which has a heritage dating back to 1979), Kingflex Insulation Co., Ltd. has grown to become a leading manufacturer of thermal and cold insulation systems. Based in Dacheng, China, we operate 5 large automatic assembly lines, delivering over 600,000 cubic meters of high-density insulation materials annually. This production capacity enables us to fulfill large-scale orders from the Ministry of Energy, Ministry of Chemical Industry, and international EPC partners on schedule.
By leveraging vertical raw material sourcing and automated, continuous vulcanization processes, Kingflex offers a cost-effective alternative to domestic European manufacturers without compromising on performance. Our products comply with European testing standards, including BS 476, CE, REACH, RoHS, UL94, and ASTM.

Comprehensive portfolio of sheets, rolls, and pre-formed tubes optimized for Norway's subsea and offshore structures
Corrosion Under Insulation (CUI) is a major driver of operational maintenance costs in offshore environments like Bergen, Stavanger, and Hammerfest. If moisture penetrates the insulation and contacts the metal pipe, corrosion can progress undetected beneath outer claddings.
Traditional insulation solutions rely on separate vapor barrier wraps. If these wraps tear during installation, moisture can enter the system. Kingflex's elastomeric foam formulation incorporates a closed-cell network where each cell acts as an independent water-resistant barrier. This design ensures that even if the outer surface is cut, the cell structure prevents moisture tracking along the pipe, maintaining long-term thermal performance.
Extreme thermal cycling from ambient temperature down to -162 °C causes metal pipes to contract. Brittle insulation materials can crack under this stress. Kingflex elastomeric materials remain flexible at sub-zero temperatures, accommodating pipe contraction without structural failure.
Rigorous laboratory analysis ensuring conformance to international standards
Continuous monitoring using heat flow meter apparatuses ensures each production run matches our certified lambda values.
Testing in accordance with BS 476 Class 0 and ASTM E84 ensures self-extinguishing performance in marine engine rooms and processing units.
Testing flexibility down to -200 °C prevents cracking caused by vibration or thermal cycling in maritime and subsea applications.
Our materials are deployed across energy transport, refining, and industrial processing systems globally
Insulating primary process piping and storage spheres at low temperatures to manage boil-off gas rates.
Providing fire protection and thermal insulation for offshore platforms operating in cold climates.
Insulating processing systems at chemical plants to maintain temperature control and prevent pipe freezing.

For high-temperature steam lines, mineral rock wool is often selected due to its thermal limits. However, in cold or cryogenic service (-40 °C to -200 °C), open-cell fibrous structures like rock wool are susceptible to moisture absorption. When water vapor enters the insulation, it condenses and freezes, compromising its thermal performance.
Kingflex closed-cell elastomeric foam prevents moisture ingress without requiring additional vapor barrier coatings. Its flexible structure also allows it to be cut and fitted around complex geometries, valves, and tees, reducing installation time on offshore hulls and pipelines.
