Providing next-generation, high-performance elastomeric thermal and cryogenic insulation systems compliant with European fire safety and environmental regulations.
Send Inquiry NowEngineered for high thermal efficiency and absolute fire safety. Recommended for critical infrastructure and shipbuilding projects in Northern Germany.
As Northern Europe’s primary maritime and industrial logistics hub, the city of Hamburg enforces some of the world's most stringent building safety and environmental protection guidelines. From the complex piping systems in the Port of Hamburg to the demanding HVAC installations in commercial complexes, halogen-free insulation is no longer an optional upgrade—it is a regulatory and functional imperative.
Halogenated flame retardants, while historically effective, release highly corrosive acid gases (such as hydrogen chloride and hydrogen bromide) and dense black smoke upon combustion. In high-density settings, maritime vessels, or sensitive cleanroom facilities in Hamburg, these emissions represent a critical threat to human life and valuable technical equipment. Halogen-free elastomeric insulation addresses this by utilizing sophisticated polymer chemistry to ensure fire retardancy while maintaining low smoke toxicity.
Understanding the engineering parameters that drive modern halogen-free thermal and cryogenic protection.
Formulated without chlorine, bromine, or fluorine. During fires, it prevents the generation of halogenated acid fumes, protecting occupants and preventing structural steel corrosion.
Boasting a closed-cell rate exceeding 98%. This minimizes moisture absorption, ensuring long-term stable thermal conductivity (λ) and preventing corrosion under insulation (CUI).
Specifically modified polymers capable of handling temperatures as low as -200°C. Ideal for Hamburg's LNG ship terminals, petrochemical lines, and extreme cold chain storage.

Tailored systems engineered to meet the operational stresses of Northern Europe's industrial hubs.
Hamburg’s shipyards require insulation materials certified under international marine standards (SOLAS / IMO). Our halogen-free solutions prevent toxic fumes in confined shipboard spaces, ensuring passenger and crew safety while providing superb condensation control on chilled water systems.
Modern commercial buildings in Hamburg aiming for DGNB (German Sustainable Building Council) or LEED credentials rely on our zero-halogen formulations. By choosing halogen-free systems, buildings avoid the risk of acidic run-off during fire events and keep Indoor Air Quality (IAQ) pristine.
With Germany expanding its LNG import capacities along the northern coastlines, cryogenic safety is paramount. Our specialized cryogenic rubber foam system provides robust, multi-layer thermal barriers for liquified gas pipes down to -200°C, maintaining elasticity and preventing stress cracking under extreme thermal shock.
Ensuring complete peace of mind for European procurement, logistics, and engineering teams.
European environmental regulations like REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) and the RoHS Directive place hard limits on hazardous substances in building products. Standard halogenated insulation contains chlorinated paraffins and flame retardants that are heavily scrutinized. Our product lines are certified halogen-free and carry independent laboratory classifications to assure smooth compliance with local German building authorities (Bauaufsicht) and safety inspectors.
We collaborate with Hamburg-based logistics networks to ensure rapid custom clearance, local warehousing availability, and standardized documentation (including EPDs - Environmental Product Declarations) required for municipal building tenders in the Hamburg Metropolitan Region.
