💡 How does Isosorbide improve the properties of Polyurethane?
Polyurethane (PU) is widely used in foams, coatings, adhesives, and automotive interiors. When Isosorbide is introduced, PU gains more than just sustainability – it delivers clear performance upgrades. 🌱⚙️
🔍 Key Benefits of Isosorbide in Polyurethane
✅ Improved Durability
The rigid cyclic structure of Isosorbide strengthens molecular interactions, enhancing tensile strength and abrasion resistance.
✅ Better Thermal Stability
Maintains structural integrity at elevated temperatures, creating PU materials with superior heat-aging resistance.
✅ Enhanced UV Resistance
Reduces yellowing and degradation under UV exposure, ideal for outdoor coatings and automotive interiors.
✅ Reduced Odor
Unlike petroleum-based raw materials, Isosorbide lowers unwanted odor, making it suitable for eco-friendly adhesives and coatings.
🏭 Application Examples
◾ Foams: Cushioning, insulation, lightweight structures
◾ Coatings: Wood & furniture coatings, protective coatings for automotive and construction
◾ Adhesives: High-performance and eco-friendly adhesives
◾ Automotive Interiors: Seats, dashboards, and other durable, UV-resistant parts
🌍 Why does this matter?
◾ Environmental Value: 100% bio-based, replacing petroleum-derived raw materials
◾ Industrial Value: Combines strength, heat stability, and UV resistance → expands high-value PU markets
◾ Sustainable Alternative: Achieves both sustainability and high performance
Sustainability is not a choice – it’s a technology
