Explore EquipmentThe European building and construction sector is experiencing a monumental paradigm shift driven by stringent decarbonization frameworks, soaring primary energy costs, and rigorous thermal performance directives. At the epicenter of this transformation is France, where the implementation of the Réglementation Environnementale 2020 (RE2020) has set unprecedented standards for thermal insulation, operational energy reduction, and embodied carbon control across residential, commercial, and industrial structures.
Extruded Polystyrene (XPS) foam board has long been recognized as the gold standard for applications requiring high compressive strength, superior moisture resistance, and stable long-term thermal resistance ($\lambda \le 0.027 - 0.029 \text{ W/m}\cdot\text{K}$). However, legacy XPS manufacturing assets across France and Western Europe face mounting pressures due to the phase-out of fluorinated greenhouse gases (HFCs) under EU Regulation No 517/2014 and its subsequent revisions. Modern French insulation producers require production lines capable of operating with zero Ozone Depleting Potential (ODP) and negligible Global Warming Potential (GWP) blowing agents without sacrificing throughput or physical board characteristics.
China Amulite Group has established itself as an authoritative technology provider, engineering complete, turnkey XPS Foam Board Production Lines custom-tailored to the operational mandates of French industrial clients. By integrating high-torque twin-screw tandem extrusion systems, micro-metering supercritical $CO_2$ gas injection, and automated downstream board handling, Amulite empowers French manufacturers to produce high-density, fire-retardant (Class E/B-s1, d0) XPS boards that dominate regional distribution networks from Île-de-France to Auvergne-Rhône-Alpes.
The global extruded polystyrene market is undergoing a rapid technological evolution. For decades, the industry relied heavily on HCFCs and HFCs to achieve uniform closed-cell structures and optimal thermal resistance. However, environmental legislation, coupled with volatile chemical supply chains, has accelerated the adoption of physical blowing agents—specifically gas-phase $CO_2$ pressurized into a supercritical state.
Supercritical $CO_2$ ($scCO_2$) possesses unique thermodynamic properties—combining gas-like diffusivity with liquid-like solvent power. Amulite’s precise gas injection systems maintain continuous operating pressure (up to 25 MPa), allowing homogeneous dispersion within the melt matrix without cell collapse.
French waste management policies (such as the AGEC law—Loi Anti-Gaspillage pour une Économie Circulaire) mandate high post-consumer recycled (PCR) content. Amulite lines integrate inline gravimetric dosing capable of processing up to 100% recycled General Purpose Polystyrene (GPPS) flake without degrading tensile strength.
Through advanced static cooling mixers and high-shear primary twin-screw extruders, Amulite equipment controls micro-cell sizing between 0.05 mm and 0.15 mm. Small, highly closed cell morphology locks in static air, minimizing radiant and conductive thermal transmission over decades.
The engineering core of the Amulite XPS production system rests on a Tandem Extrusion System (Primary Co-rotating Twin-Screw Extruder paired with a Secondary Single-Screw Cooling Extruder). This decoupled approach separates high-shear plasticization and additive dispersion from low-shear temperature homogenization, preventing heat degradation of flame retardants and ensuring optimal melt viscosity prior to die exit.

Amulite integrates liquid-driven diaphragm metering pumps fitted with mass flow meters capable of real-time closed-loop monitoring. $CO_2$ is maintained above its critical pressure (7.38 MPa) and temperature (31.1°C), ensuring instantaneous, high-solubility mixing into the PS melt during high-volume production runs.
The secondary cooling extruder utilizes oil-circulated thermal zones paired with high-efficiency static coolers. Reducing the melt temperature evenly to approximately 110°C–120°C is critical to achieving maximum melt strength, preventing bubble coalescing or board warping upon ambient pressure relief.
Extruded foam exiting the sheet die passes through a high-precision multi-stage calibrator. Automated downstream equipment executes skin removal, high-speed edge shiplap/tongue-and-groove profiling, cross-cutting, and robotic stacking—delivering factory-ready boards with zero manual handling requirements.
In accordance with French safety norms and European REACH restrictions, Amulite machinery is optimized to process non-toxic Polymeric Flame Retardants (PolyFR), preserving mechanical integrity while achieving Euroclass B-s1, d0 fire rating.
XPS boards produced on Amulite production machinery serve high-value, specialized building applications across France's distinct climatic zones—from the moisture-heavy coastal regions of Brittany to the alpine environments of Savoie.
In urban renovation projects across Paris, Lyon, and Marseille, inverted flat roofs place severe stress on insulation. Amulite-produced XPS boards offer near-zero water absorption (< 0.7% by volume under long-term total immersion per EN 12087) and exceptional freeze-thaw endurance.
External Thermal Insulation Composite Systems (Système d'Isolation Thermique par l'Extérieur - ITE) represent a major growth driver in France. Amulite’s inline surface grooving module creates textured, dust-free board faces optimized for mechanical anchoring and cementitious render adhesion.
France’s massive food processing and cold storage hubs demand floor insulation capable of withstanding extreme hydrostatic pressure and continuous mechanical load. Amulite lines can configure board compressive strength up to 1200 kPa without excessive material usage.
Amulite Group maintains an aggressive R&D strategy, anticipating legislative shifts and digital integration trends within Western European markets. Our continuous equipment upgrades ensure client assets remain future-proof over a 20-year operational lifecycle.
Amulite is collaborating with material scientists to validate bio-monomer PS blends and nanocellulose reinforcing agents. Early trials demonstrate a 15% increase in flexural modulus, allowing board thickness reduction while maintaining structural integrity.
Integrating machine vision thickness scanners with auto-thermal expansion die bolts, Amulite's next-gen control system adjusts sheet profile variations in real-time (< ±0.2 mm tolerance), virtually eliminating post-extrusion planing waste.
All edge trims, surface dust, and off-spec boards are processed through an inline granulation and dust-compacting circuit. Recycled material is automatically reintroduced to the primary feed hopper at calibrated ratios without manual labor.
Full SCADA integration delivers live tracking of kWh per cubic meter of XPS produced, $CO_2$ mass consumption rates, and predictive motor maintenance alerts linked directly to French plant management dashboards.
Investing in a high-capacity XPS manufacturing facility requires more than individual machines; it demands full plant engineering, layout optimization, utility design, and regulatory compliance assistance.
