2. Outstanding Mechanical Properties
Polyurethane insulation exhibits excellent tensile strength, elongation at break, impact resistance, and wear resistance. It also provides high resistance to cutting and tearing, making it ideal for long-term use in demanding environments.
3. Flexible Design and Aesthetic Appeal
The technology used for polyurethane insulation casting is simple and versatile, allowing for a wide range of aluminum profile designs without special requirements. This enables the creation of diverse window styles—such as sliding, tilting, folding, and custom-shaped windows—as well as curtain wall systems. After heat treatment, the aluminum profiles maintain their original color, strength, and aesthetic appeal while significantly enhancing thermal efficiency.
4. High Production Efficiency
The production process is streamlined, combining pouring, curing, and bridge-breaking into one step. This makes it suitable for mass and continuous production, increasing productivity and reducing manufacturing time.
5. Reduced Aluminum Consumption
Compared to traditional insulation methods, using polyurethane casting requires about 10% less aluminum to achieve the same insulation effect. Additionally, the seamless production process minimizes aluminum waste, with loss rates as low as 1-2%, making it more cost-effective and sustainable.
6. Prevention of Glass Condensation
Polyurethane insulation effectively reduces condensation on glass surfaces caused by poor building quality or temperature fluctuations, improving overall performance and user experience.
7. UV Resistance
Even after prolonged exposure to ultraviolet rays, the mechanical properties of the insulation material remain stable, ensuring long-term safety and durability of the aluminum profiles.
8. Suitable for Humid Environments
Being a non-absorbent polymer, the polyurethane adhesive retains its full performance even after being fully soaked in water, making it ideal for use in rainy or humid climates.
9. Strong Seismic Resistance
The viscoelastic bonding between the polyurethane insulation and aluminum profiles ensures flexibility and resilience. With an elongation at break of over 20%, it helps maintain structural integrity during seismic events.
10. Performance in Extreme Temperatures
Polyurethane insulation is a thermosetting polymer designed to withstand extreme temperatures, from -41°C to 50°C. It maintains its mechanical properties under these conditions, meeting national safety standards.
11. Environmentally Friendly
The insulating plastic is free from volatile organic compounds (VOCs) and harmful heavy metals, making it a safe and eco-friendly choice that does not harm human health or the environment.
