Polyurethane (PU), as an important polymer material, is experiencing industry development trends driven by multiple factors including environmental upgrades, technological innovation, application expansion, and changes in the global supply chain.
Environmental Protection and Sustainable Development
- Bio-based/Biodegradable PU: Research and development of bio-based polyurethanes using raw materials such as vegetable oils and starch is accelerating, reducing reliance on petroleum.
- Green Processes: Low-VOC products such as water-based PU and solvent-free PU are replacing traditional solvent-based products, responding to global carbon reduction policies.
- Recycling Technology: Chemical recycling (such as alcoholysis) and physical recycling technologies are improving, promoting the circular utilization of waste PU foams, tires, etc.
Technological Upgrades and Innovation
- High Performance: High-temperature resistant, high-elasticity, flame-retardant, and other special PU materials are meeting high-end demands (such as aerospace and military industries).
- Intelligent Manufacturing: Internet of Things and AI technologies are optimizing production processes, improving energy efficiency and product quality stability.
- Composites: Composites with nanomaterials, graphene, etc., are enhancing functionality (such as conductivity and antibacterial properties).
