View SpecsAs the largest seaport city in Germany and a critical global logistics hub, Hamburg is enforcing aggressive sustainability policies. Under the European Green Deal and German GEG (Gebäudeenergiegesetz - Building Energy Act), industrial and building systems are subject to strict carbon footprint constraints. Traditional thermal insulation materials containing brominated or chlorinated flame retardants (halogens) are increasingly restricted due to their potential to release highly toxic, corrosive acid gases during combustion.
In municipal utility sectors like district heating networks (Fernwärme), ship engineering at the Port of Hamburg (including shipyards like Blohm+Voss), and micro-tech chemical processing units, the utilization of Halogen-Free insulation is critical. When standard insulation burns, it releases acidic vapors (hydrogen chloride and hydrogen bromide) that destroy high-value electrical controllers and pose severe inhalation risks to humans. Switching to halogen-free systems mitigates these liabilities entirely.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for high-end thermal insulation products. Our advanced research development and production center is situated in the well-known capital of green building materials in Dacheng, China. As an energy-saving, environmental friendly enterprise, Kingflex concentrates heavily on the R&D, manufacturing, and global commercialization of elastomeric foam materials.
In all operations, Kingflex views energy optimization and carbon footprint reduction as core targets. We supply complete thermal insulation configurations via end-to-end consulting, professional custom R&D, precision manufacturing, engineering installation guidance, and dedicated post-sale engineering services to lead progress in the building materials industry.
Kingflex was established by the Jinwei Group, which commands over 40 years of industrial manufacturing heritage since its founding in 1979. It was the first manufacturer of modern thermal insulation products north of the Yangtze River in China, providing us with deep chemical expertise and high manufacturing stability.
Understanding the exact chemical differences between traditional elastomeric rubber foam (typically containing NBR/PVC and halogenated fire retardants) and dedicated Halogen-Free materials is vital for engineers designing modern infrastructure in Northern Germany.
| Performance Parameters | Kingflex Halogen-Free Rubber Foam | Standard NBR/PVC Rubber Foam | Rock Wool / Mineral Wool Insulation |
|---|---|---|---|
| Halogen Content | 0% (Totally Free of Chlorine, Bromine, Fluorine) | Contains Chlorinated Polymers/Flame Retardants | 0% (Typically Inorganic) |
| Smoke Emission Toxicity | Zero acid gases, low smoke density (EN 13501-1 s1) | Releases Corrosive HCl and HBr gas under fire | Non-toxic but releases dust/particles |
| Moisture Resistance (μ) | ≥ 10,000 (Built-in Vapor Barrier) | ≥ 7,000 | < 5 (Requires external vapor barrier) |
| Thermal Conductivity (λ) | ≤ 0.034 W/(m·K) at 0°C | ≤ 0.032 W/(m·K) at 0°C | ≤ 0.040 W/(m·K) at 50°C |
| Physical Flexibility | High flexibility, easy installation in tight spaces | High flexibility | Rigid or semi-rigid, prone to fragmentation |
Our employees are outstanding in their fields, work cohesively, and operate with a shared vision of delivering reliable quality and service. Kingflex employs eight expert chemical engineers in our R&D department, six international sales representatives, and over 230 technicians on our production lines.
Our facility operates 5 large-scale automated assembly lines. Having an annual production capacity exceeding 600,000 cubic meters allows us to easily handle massive commercial developments while maintaining designated supplier standing with major regional energy and chemical ministries.
Northern Germany has unique structural needs due to marine atmospheric conditions and strict regional energy requirements. Kingflex Halogen-Free insulation addresses several of these environments:
Marine environments require absolute safety on offshore platforms, cruise ships, and cargo liners. Kingflex Halogen-Free insulation meets stringent marine safety guidelines (such as the IMO FTP Code), ensuring no acid gas release in high-occupancy marine cabins.
HafenCity and adjacent urban developments in Hamburg demand strict eco-compliance and fire safety. Closed-cell technology prevents condensation in humid, seaside urban microclimates while maximizing long-term energy savings.
With terminal upgrades near Hamburg, cryogenic transport is expanding. Kingflex cryogenic system rubber foam maintains thermal control and mechanical resilience down to extreme low temperatures, mitigating the risk of pipe cracking.
Kingflex continually refines its production lines, aiming to keep pace with changing eco-specifications and building code demands in European industrial markets:
Developing formulations using natural oils to replace standard petroleum bases, cutting the embodied carbon footprint of our insulation products.
Modifying micro-cell geometry to achieve thermal conductivity values down to λ ≤ 0.030 W/(m·K), reducing energy losses in cold piping systems.
Deploying take-back recycling options for construction site off-cuts to assist projects in meeting circular economy goals.
To support major engineering designs globally and locally in Hamburg, Kingflex products undergo complete chemical and physical testing. Our products hold certificates for BS 476, CE, REACH, RoHS, UL94, and ASTM, verifying consistent compliance and physical properties.
We manage direct transport to Central and Northern Europe. Supported by our skilled logistics partners and structured tracking procedures, we maintain reliable supply timelines for port operations, chemical factories, and construction sites across the Hamburg Metropolitan Area.
