2. Outstanding Mechanical Properties: This polyurethane insulation material offers excellent tensile strength, elongation at break, impact resistance, wear resistance, and cut resistance. Its high durability makes it ideal for long-term use in demanding environments.
3. Flexible Design and Aesthetic Appeal: With a simple casting process, this technology allows for diverse window styles, including sliding, folding, and tilt-and-turn designs. It supports custom shapes like circular windows and curtain walls while maintaining the original color, strength, and elegant appearance of aluminum profiles.
4. High Production Efficiency: The process of pouring, curing, and bridging is completed in one step, making it suitable for mass production and continuous manufacturing. This significantly improves productivity and reduces labor costs.
5. Reduced Aluminum Consumption: Compared to other insulation methods, this polyurethane casting technique uses up to 10% less aluminum to achieve the same level of insulation. Additionally, the seamless production minimizes aluminum waste, with losses typically below 1-2%.
6. Minimizing Condensation on Glass: By improving thermal performance, this insulation method effectively reduces condensation on glass surfaces, enhancing building quality and indoor air quality.
7. UV Resistance: The insulating material maintains its mechanical properties even after prolonged exposure to ultraviolet rays, ensuring long-term stability and safety for aluminum doors, windows, and curtain walls.
8. Suitable for Humid Environments: Being a non-absorbent polymer, the polyurethane adhesive retains its performance even after full water immersion, making it ideal for use in rainy or humid climates.
9. Strong Seismic Resistance: The visco-elastic bonding between the insulation material and aluminum profiles, combined with an elongation at break of over 20%, ensures structural integrity during seismic events.
10. Reliable Performance in Extreme Temperatures: This thermosetting polymer can withstand extreme temperatures ranging from -41°C to 50°C, maintaining its mechanical properties and meeting national standards for insulation performance.
11. Environmentally Friendly: The insulation plastic is free from volatile organic compounds (VOCs) and harmful heavy metals, making it safe for both human health and the environment. It’s a sustainable choice for modern construction.
