Foam Extrusion Line
Advanced Physical Foaming Technology for Lightweight Polymer Products
Our Supercritical CO₂ Foam Extrusion Line adopts advanced SC-CO₂ physical foaming technology to produce high-performance lightweight foam materials. By precisely controlling pressure, temperature, and CO₂ dosage, the system generates a uniform microcellular structure with excellent mechanical properties and surface quality.
Compared with chemical foaming processes, this technology offers:
1.Eco-friendly production (no chemical residue)
2.Lower material consumption
3.Stable cell structure control
4.Adjustable density range
5.High-efficiency continuous production
6.Sustainable and recyclable processing

This Solution Covers Three Major Product Categories:
Foam Board
Foam Board refers to rigid, thick foamed panels designed for structural and insulation applications. The line features precise calibration, strong cooling systems, and high-load extrusion capability.
Foam Sheet
Foam Sheet is a thin, flexible foamed plastic sheet produced through precision extrusion and foaming technology. It is widely used in packaging and thermoforming applications.
Foam Bead
Continuous Bead Foam technology produces uniform foam beads via extrusion foaming and pelletizing systems. These beads are used for secondary molding into high-performance lightweight products.
