Foam Insulation Board Extrusion (XPS Extrusion) Lines

Advanced CO₂ Blowing Technology for Sustainable Thermal Insulation

Sunwell Global leads the industry in engineering high-efficiency XPS (Extruded Polystyrene) foam insulation board extrusion lines.

Our systems are precision-engineered to produce high-density, closed-cell insulation boards that offer superior thermal resistance and mechanical strength, catering to the strict energy-saving requirements of modern green building and civil engineering projects.

Key Technological Advantages

1. Eco-Friendly CO₂ Blowing Agent System

In response to global environmental regulations, Sunwell Global offers state-of-the-art CO₂/Butane blowing agent technology. This ODP (Ozone Depletion Potential) and GWP (Global Warming Potential) friendly solution ensures your production meets international environmental standards while maintaining excellent foaming quality.

2. High-Precision Tandem/Dual-Screw Extrusion

Our lines utilize a specialized tandem or co-rotating dual-screw system that ensures optimal homogenization of the PS melt and blowing agents. This technical precision results in a consistent, uniform cell structure, which is critical for long-term thermal insulation performance (R-value).

3. Superior Mechanical Strength & Dimensional Stability

Sunwell-engineered XPS boards are known for their exceptional compressive strength, making them ideal for high-load applications. Our advanced cooling and calibrating units ensure that every board maintains strict dimensional stability, reducing scrap and ensuring high-quality output.

4. Advanced Dosing and Metering Precision

Equipped with high-accuracy loss-in-weight feeders and liquid injection pumps, our systems provide exact control over raw materials and additives (such as fire retardants and colorants). This precision minimizes material waste and guarantees product consistency.

FAQ

Q: Does Sunwell Global’s XPS line support eco-friendly blowing agents?

A: Yes. We specialize in CO₂-based blowing technology, which is the global standard for environmentally friendly XPS production. This technology replaces traditional CFCs/HCFCs, allowing manufacturers to comply with strict international green building regulations and carbon footprint targets.

Q: How does Sunwell Global ensure the high compressive strength of XPS boards?

A: Strength is achieved through our precision dual-screw extrusion process and specialized cooling calibrators, which create a fine and uniform closed-cell structure. This structure enables the boards to withstand high mechanical loads while maintaining their insulation properties over decades.

Q: Can recycled PS (rPS) be used in your XPS extrusion lines?

A: Absolutely. Our screw designs and filtration systems are engineered to handle high ratios of recycled PS without compromising the board's quality. This capability significantly reduces production costs and supports a circular economy.
