R&D Strength

1

Yuefeng Mica's R&D strength focuses on technological innovation, industry-university-research collaboration and achievement transformation

I. Technology System and Investment
We have established a three-in-one structure encompassing "R&D Center - Production Base - Application Laboratory," with a total investment of 350 million yuan and over 150 pieces of specialized equipment. Focusing on technological breakthroughs across the entire industry chain, our core products, such as flame-retardant mica components for power batteries (resistant to 1200°C), have been adopted by companies such as BYD and CATL, supporting the needs of 800V high-voltage platforms.
II. Industry-Academic-Research and Talent
Through joint laboratories, we have deepened collaboration with universities. Our R&D team, comprised of professionals in materials and polymers, has achieved breakthroughs in replacing proton exchange membranes in fuel cells with mica membranes (expected to reduce costs by 50%) and developed products such as environmentally friendly mica sheets.
III. Patents and Standards
We have acquired over 100 intellectual property rights, with core patents such as the "Mica Paper Mechanical Strength Testing Device" added in 2025. We have also led or participated in the development of over 10 national and industry standards (such as the national standard for "Refractory Mica Tape"), solidifying our voice in the industry. IV. Core Technology Breakthroughs
New Energy: Multi-layer composite flame-retardant components account for 35% of the global power battery mica tape market share;
High-Temperature Insulation: Mass production of 0.05mm ultra-thin mica tape (insulation strength 20kV/mm) and 3-100mm ultra-thick mica sheets (low thermal conductivity at 750°C);
Green Manufacturing: Digital control throughout the entire process has increased capacity utilization to 85%, while tailings recovery technology has increased waste utilization to over 90%.
V. Industry Impact and Transformation
With international certifications such as UL and CE, our products are exported to 30 countries and we participate in the development of IEC international standards. Our achievements are being applied in areas such as ultra-high voltage lines (annual demand increases by 18,000 tons), domestically produced materials for nuclear power plants, and consumer electronics (flexible heating films account for 60% of the global electric heating table market share).
