At Yongjia Polyurethane, we are proud to introduce our state-of-the-art PU Sandwich Panel Production Line, a testament to advanced technology and innovation. Our production line is designed to manufacture rigid polyurethane sandwich panels, which are known for their exceptional thermal insulation properties.
Key Features of Rigid Polyurethane:
1. Low Thermal Conductivity:
Rigid polyurethane boasts impressive thermal performance with a thermal conductivity of only 0.018w~0.023w/(m·k) when its density is between 35~40kg/m³. This makes it one of the most efficient insulating materials available today, offering approximately half the thermal conductivity of EPS.
2. Moisture and Water Resistance:
With a closed cell ratio exceeding 90%, rigid polyurethane is hydrophobic, ensuring that moisture does not compromise its thermal efficiency. Its moisture-proof and waterproof capabilities protect against water penetration, maintaining the integrity of your insulation.
3. Fire Resistance and High-Temperature Tolerance:
When flame retardants are incorporated, polyurethane transforms into a self-extinguishing material. It withstands high temperatures, with a softening point above 250°C, and decomposition occurs only at elevated temperatures. In case of fire, polyurethane foams to create a protective ash layer, effectively curbing fire spread and safely avoiding the release of harmful gases.
Production Line Methods:
Our production line offers two distinct methods tailored to different production needs:
1. Continuous Production:
Ideal for large volume manufacturing, this process ensures a steady output of standard PU sandwich panels. The continuous method guarantees consistent quality and efficiency across the production run.
2. Discontinuous Production:
Designed for special shaped products or smaller production runs, this method allows for flexibility where continuous equipment investment may not be viable. In the discontinuous process, surface materials are individually formed, cut to size, and then assembled into the laminator. Foam is injected between these surfaces to form predefined PU sandwich panels, offering customizability and adaptability for unique projects.
Conclusion:
By investing in the Yongjia Polyurethane PU Sandwich Panel Production Line, you gain access to cutting-edge technology that delivers superior thermal insulation solutions. Whether you require continuous or discontinuous production methods, our versatile lines cater to diverse market demands. Embrace the future of insulation with Yongjia Polyurethane – where quality, efficiency, and safety meet innovation.If you need it, you can contact us：email：info@machinepu.net.
