Foamed Reinforced Sheet Extrusion Lines
Technical Description
Cutting-Edge Advancements in Foamed Reinforced Sheet Extrusion 1. Physical Foaming via Microcellular Structure Technologies MEAF delivers foamed sheets (0.15–2.5 mm thickness) using physical foaming with N₂ or CO₂ that reduces density by up to 30% while maintaining mechanical strength. These systems support multi-layer constructions (up to 7 layers), outputting up to 1,500 kg/h and enabling full recyclability and regrind usage 2. High-Performance PP Foamed Sheets for Packaging Upgraded extrusion systems now achieve 40% material savings, producing structured PP A/B/A sheets with a lightweight core (0.55 g/cm³). These lines handle up to 1,850 kg/h with significant regrind incorporation and feature tailored foaming packages and advanced roll-stack tech for precision thickness and surface finish 3. Dynamic & Static Mixing Innovations Introduced retrofittable dynamic mixing and static melt cooling modules that enhance melt homogeneity and facilitate a shift from chemical to CO₂-based physical foaming. These upgrades reduce density, eliminate foam masterbatch usage, and achieve line outputs up to 1,500 kg/h, increasing cost efficiency and sustainability 4. Advanced Control, Automation & Sustainability Emerging foam extruder lines now incorporate AI-enabled closed‑loop control systems, which continuously monitor and adjust temperature, pressure, density, thickness, and surface quality. They also use optical or laser-based sensors for real-time feedback, improving precision and reducing waste. New eco-blowing agents like CO₂ or water-based alternatives provide environmentally safer options 5. Material Innovation & Cellular Design Research efforts demonstrate improvements using nano-enhanced and composite fillers: PP/talc nanocomposite foams show improved strength and rigidity. PP with short glass fibers and carbon nanotubes boosts vibrational damping and stiffness. PLA foamed via tandem extrusion with nanoclays and CO₂ increases cell density and expansion ratio
