Nine Patents Granted on the Same Day! Yinuowei Demonstrates the Strong Confidence of Domestic Materials

On April 17, patent announcements on the website of the China National Intellectual Property Administration revealed that Yinuowei has been granted 9 invention patents, covering several key sub-sectors of polyurethane, including temperature-resistant polyurethane sports protective materials, ultra-low thermal conductivity, high-performance flame-retardant polyether polyols for home appliances, flame-retardant bio-based polyurethane sealants, and bio-based flame-retardant polyurethane foaming adhesives. The successful acquisition of this batch of patents represents a significant achievement resulting from the company’s more than two decades of dedicated research and development in the field of polyurethane materials and its ongoing commitment to technological innovation. It also exemplifies Yinuowei’s alignment with the national strategy for developing new materials, leveraging original technologies to break industry bottlenecks, promote the high-end transformation of the sector, and strengthen the foundation for domestic substitution.

As a national-level demonstration enterprise for manufacturing single-champion products, Yinuowei focuses on its core polyurethane business and regards technological innovation as the core driving force behind high-quality development. The company aligns precisely with the national strategic priorities of fostering new productive forces, promoting the green and low-carbon transformation of the chemical industry, and achieving independent and controllable access to high-end new materials. Currently, as new applications for polyurethane materials continue to expand, the industry faces challenges such as insufficient performance and functionalization, as well as heavy reliance on imported high-end products. The nine invention patents recently approved represent differentiated technological innovations that have effectively addressed these specific pain points in niche markets.

To address the longstanding challenge of poor reaction stability in conventional amine-based polyether raw materials, a new patent for amine-based polyether polyols reconfigures the synthesis route and optimizes the catalytic system, thereby enhancing raw-material quality and stability at the source. In response to the energy-saving and fire-protection needs of household appliances, a breakthrough in ultra-low thermal conductivity, high-performance, flame-retardant polyether polyol technology overcomes traditional limitations, providing critical support for the green upgrade of the home-appliance industry. To tackle the challenges of municipal and transportation infrastructure maintenance, a specialized polyurethane formulation for road repair resolves issues such as difficult low-temperature construction and low curing efficiency, enabling all-weather, long-lasting durability. Focusing on the green and low-carbon trend in the building-materials sector, the company has developed a series of bio-based polyurethane products that break through the bottleneck of “trade-offs between environmental friendliness and performance,” achieving synergistic improvements in both low carbon emissions and practical functionality. Other patents likewise target performance gaps in material applications, filling critical technological voids across the industry value chain.

Breakthroughs in technological innovation are inseparable from a robust systemic support framework. Relying on high-end platforms such as the Postdoctoral Research Workstation and the Shandong Provincial Engineering Technology Research Center, Yinuowei has established an innovation system characterized by deep integration among industry, academia, research, and application, attracting top talent to tackle cutting-edge challenges. To date, the company has been granted more than 500 authorized invention patents, has played a leading role in the development of over 20 national and industry standards, and has gained decisive influence over core technologies. Several of its technologies have filled domestic gaps and reached internationally advanced levels, effectively breaking overseas monopolies, steadily advancing the localization and substitution of high-end polyurethane materials, and injecting momentum into cost reduction and efficiency enhancement in manufacturing as well as greater autonomy and controllability across the industrial value chain.

While consolidating its strengths in traditional sectors, Yinuowei is proactively positioning itself in emerging industries. Its patented high-end TPU products, with their outstanding fatigue resistance, exceptional toughness, and lightweight characteristics, are well-suited to the precision requirements of intelligent equipment, thereby providing critical support for the upgrade of high-end machinery. At the same time, aligned with the “dual carbon” goals and the broader trend of new-energy development, the company is ramping up R&D investment in bio-based materials, deepening its expertise in polyurethane materials for new-energy applications, and building multi-dimensional technological competitive advantages.

Technological self-reliance and strength are the core essence of high-quality industrial development, with cumulative original innovation serving as the fundamental source and foundation of such self-reliance. The recent centralized grant of nine patents marks a significant milestone in Yinuowei’s journey of innovation. Moving forward, Yinuowei will steadfastly uphold its innovation-driven strategy by increasing R&D investment, accelerating the commercialization of research outcomes, staying focused on its core business, building up expertise over generations, and pursuing sustained, long-term efforts. Through its robust scientific and technological capabilities, Yinuowei will advance the higher-level, independently controllable development of domestically produced polyurethane materials, thereby contributing the company’s strength to the building of a manufacturing powerhouse, a quality powerhouse, and a green China.
