Explore SpecificationsMorocco is rapidly positioning itself as a primary gateway for international trade, logistics, and renewable energy development between Europe and Africa. Supported by initiatives such as the national Green Hydrogen Roadmap ("Offre Maroc") and massive investments in seaport infrastructure (such as Tanger Med and the new Nador West Med port), the country is witnessing an unprecedented surge in demand for specialized cryogenic technologies. These initiatives demand top-tier thermal safety profiles, strict containment solutions, and high-efficiency insulation designs to curb energy boil-off rates (BOG).
From liquefied natural gas (LNG) imports in Jorf Lasfar to ammonia storage facilities required for OCP Group's international fertilizer value chain, cryogenic insulation acts as a critical security and economic driver. Extreme external temperatures in North Africa mean that standard insulation materials fail prematurely due to high thermal stresses and rapid moisture intrusion. Using high-density, multi-layer NBR/PVC closed-cell systems prevents thermal bridging, controls moisture vapor transfer, and mitigates the severe risks associated with Corrosion Under Insulation (CUI).
Established under the prestigious Jinwei Group (originating in 1979 as a pioneer of insulation in Northern China), Kingflex Insulation Co., Ltd. has developed into a global leader in high-performance green-building materials, specialized thermal elastomers, and cryogenic insulation systems.
We provide full-lifecycle technical support, from project conception, density & thickness calculation, and pre-sales guidance to localized shipping logistics and customized installation supervision. Operating 5 modern automated production lines, Kingflex is a certified supplier to major global chemical, petrochemical, and power ministries, ensuring consistent thermal barrier properties down to -200 °C.
Understanding the NBR/PVC closed-cell structure and performance metrics under severe thermal stress.
At ultra-low temperatures, standard materials contract and crack, losing their air-tight properties. Kingflex's customized NBR/PVC matrix features an evenly-distributed closed-cell rate exceeding 98%. This unique cellular structure prevents water vapor molecules from penetrating the cold boundary, maintaining low thermal conductivity over a service lifetime of 10 to 15 years.
Corrosion Under Insulation (CUI) Mitigation: Unlike traditional glass wool or rock wool, which absorb moisture, our flexible elastomeric material does not trap water against the steel pipe walls. This eliminates the chemical and atmospheric conditions that trigger galvanic and localized pitting corrosion, drastically reducing maintenance downtime in marine or industrial coastal zones like Safi, Mohammedia, and Jorf Lasfar.

Our products undergo rigorous multi-point validation to ensure safe implementation in global extreme-cold systems.
We maintain full chemical and structural traceability for every production batch. Our cryogenic insulation range holds certifications under European Standards (CE), British Standards (BS 476), RoHS, REACH, UL94, and ASTM, meeting the strict design criteria of Moroccan governmental and private sector tenders.
Whether you require standard thicknesses of 9mm or extreme layered configurations up to 50mm, our eight R&D engineers customize performance attributes to withstand high mechanical pressures and chemical exposure.
Proven execution of Kingflex insulation materials in complex industrial, cold storage, and energy projects.
Marine environments, such as those found around the Port of Casablanca, present a dual challenge: high ambient temperatures combined with relative humidity levels that often exceed 85%. These conditions force cold pipe surfaces (such as those carrying chilled glycol or liquid gases) to sweat constantly. Our standard dimension sheets and pre-split pipes are designed to handle these environmental pressures.
Our solutions prevent moisture build-up and surface condensation. This maintains the structural stability of the insulation, keeping the project site clean and energy-efficient.
Direct technical answers from our engineering group regarding installation, certification, and procurement in North Africa.
A1: PU foam is rigid, prone to fracturing under mechanical stress, and requires complex field jointing and external vapor barrier wraps. Kingflex NBR/PVC rubber foam is flexible, conforms easily to complex pipeline geometries, and has a built-in closed-cell vapor barrier (>98% cell structure), saving installation labor and materials.
A2: Yes, our products are self-extinguishing and meet British Class 0/Class 1 (BS 476) and American UL94 V-0 flame ratings. This fulfills the safety criteria for heavy chemical industries, commercial HVAC installations, and residential complexes in Morocco.
A3: Coastal humidity increases the risk of surface condensation. Our engineering team calculates the required thickness based on Casablanca or Tanger Med's peak relative humidity (often up to 88% RH) and ambient temperatures, ensuring the outer surface of the insulation stays above the dew point.
A4: Yes, we provide full OEM and ODM services. We manufacture custom pipe diameters, sheet thicknesses (6mm up to 50mm), and adhesive-backed rolls tailored to specific engineering drawings and project requirements.
A5: Kingflex materials conform to BS 476, CE, REACH, RoHS, UL94, and ASTM. This compliance simplifies regulatory approvals for infrastructure projects throughout the European Union and North Africa.
A6: Every production batch is logged with a unique batch number, tracking the raw material inputs, assembly line conditions, and post-production quality checks. Test reports are issued prior to departure from our facility.
A7: Under correct installation and design guidelines, Kingflex NBR/PVC elastomer systems deliver a service life of 10 to 15 years, maintaining thermal efficiency and resisting structural decay.
A8: We handle shipping to all major Moroccan commercial ports, including Casablanca and Tanger Med, using robust packaging to protect the physical properties of the elastomer during transport.
