1. Exceptional Thermal Insulation Performance
-Low Thermal Conductivity
Our polyurethane insulation boards boast a remarkable thermal conductivity coefficient of **0.022-0.035 W/(m·K)**, setting a new standard in energy efficiency. Compared to traditional materials such as polystyrene foam, with its higher coefficient of **0.038-0.041 W/(m·K)**, our boards offer superior insulation capabilities, significantly minimizing heat loss. For instance, a 4 cm polyurethane board is as effective as an 8 cm polystyrene board in canal insulation, doubling the efficiency while maintaining compact dimensions.
-Broad Temperature Adaptability
Engineered for extreme conditions, our panels excel in temperatures from **-70°C to 130°C**. They resist brittleness in frigid environments and uphold their thermal oxidation stability in intense heat, ensuring consistent performance regardless of climate.
2. Superior Physical and Chemical Properties
-Lightweight Yet High Strength
Crafted with an impressive low density of **30-50 kg/m³** combined with a compressive strength of **≥0.8 MPa**, these panels significantly reduce the structural load without compromising on strength and durability, perfect for robust yet lightweight construction.
-Water and Moisture Resistance
Designed to excel in moist conditions, our panels have a water absorption rate of just **0.12%**, ensuring they maintain performance stability even when submerged for extended periods, making them ideal for damp and humid environments.
-Flame Retardancy and Safety
Certified for safety, these UL-rated panels feature a **FV-0 rating**, meaning they are self-extinguishing and provide substantial fire hazard reduction, ensuring peace of mind.
3. Construction Efficiency and Cost-Effectiveness
-Ease of Construction
Innovative prefabricated boards offer seamless installation, while on-site foaming fills intricate structures. With an adjustable curing time ranging from 1 to 24 hours, they eliminate the need for costly heating equipment, maximizing installation efficiency and reducing labor costs.
-Long-Term Economic Benefits
Despite a 30% higher initial investment compared to polystyrene, the long-term savings are substantial. An example includes an electronic transformer factory which, after switching to polyurethane, eliminated stress-related product returns and saved millions annually, showcasing the economic advantage over time.
4. Environmental and Functional Versatility
-Eco-Friendly
Our panels are solvent-free and emit no harmful gases during curing, ensuring compliance with stringent environmental standards and promoting a healthier planet.
-Multifunctional Adaptability
With the capability to adjust formulas for varying hardness levels (Shore A10 to D80), our panels exhibit exceptional adhesion to diverse substrates such as metal and plastic, and offer additional benefits like noise reduction and vibration damping, catering to a wide array of applications.
5. Weather Resistance and Long-Term Stability
-Aging and Weathering Resistance
Engineered to withstand the elements, these panels maintain optimal performance under UV exposure, acid rain, and other harsh conditions, boasting an outstanding service life of over 20 years.
-Low Thermal Expansion
Featuring a minimal linear expansion coefficient, our panels effectively reduce internal stress during temperature changes, preventing structural cracks and ensuring long-term stability and integrity.
