Industry-related Questions
Polyurethane products' performance variations in diverse climates are primarily influenced by temperature, humidity, UV radiation, and oxidation. Mitigation strategies involve optimizing material formulation, processing techniques, structural design, and post-treatment protection.
Compared to conventional insulation materials (e.g., rock wool, glass wool, EPS/XPS polystyrene, phenolic foam), polyurethane (PU) excels in key areas such as energy efficiency, durability, and multi-function adaptability. Its ultra-low thermal conductivity, high strength, waterproofing, and installation flexibility ensure superior energy-saving efficiency, space utilization, and long-term reliability. While flame retardancy upgrading and eco-friendly blowing agent promotion remain priorities, PU's comprehensive performance makes it the preferred choice for high-end insulation in industrial, construction, and transportation sectors.
Our products are widely used in construction (exterior walls, roofs, floors), cold chain storage (refrigeration panels), automotive, bridges/tunnels, coal mine reinforcement, and water conservancy projects.
Wanhua polyurethane foams achieve various flame-retardant standards (B1, B2, A-0, oxygen index 28/25 for commercial vehicles) through structural flame-retardant polyether and additive technology.
Wanhua’s waterborne polyurethane mortar has passed the rigorous FDA certification process, demonstrating safety, hygiene, and reliability.
Chemical products are accompanied by bilingual (Chinese/English) MSDS files, accessible for instant online download.
Product lifespan can be extended via a "formulation-process-protection" trinity strategy:
Mild environments (e.g., indoor construction): Up to 30 years, approaching concrete durability.
Severe environments (e.g., outdoor, chemical exposure): 10–20 years with regular maintenance.
Future innovations include self-healing polyurethane (microcapsule-sealed repair agents) and bio-based PU to reduce environmental degradation sensitivity.
 All polyurethane products comply with China’s environmental protection standards and meet national regulatory requirements.
