On the afternoon of April 22, the expert panel and organizing committee representatives of the "Third Guangdong-Hong Kong-Macao Greater Bay Area Top 50 Innovative New Materials Enterprises" conducted an on-site inspection at Guangzhou Mayer Technology Development CO.,Ltd.(hereinafter referred to as "Mayer Technology"). The delegation was joined by Lin Zhao, Vice President of the Guangdong Industrial New Materials Industry Association, and Yin Hong, Investment Director of Sany Venture Capital. Mayer Technology's Deputy General Manager Feng Hongwei and Senior Engineer Li Xuwen warmly received the delegation and accompanied them throughout the visit.

This research focuses on the innovation potential and industrialization capabilities of the new materials sector, aiming to facilitate resource integration across the industrial chain and promote collaborative industry upgrading—a goal that aligns closely with Mayer Technology's deep expertise in phase-change energy storage materials and its innovation-driven development philosophy. As China's leading producer of PCM inorganic phase-change energy storage materials, Mayer Technology is backed by its Hong Kong-listed parent company Huiyuan Cowins (01116.HK) and is a core member of the national "Specialized, Refined, Unique, and Innovative 'Little Giant' " enterprise program. The company operates nine automated production lines with an annual capacity of 20,000 tons, making it the first domestic enterprise to possess comprehensive production capabilities for PCM inorganic phase-change materials. During the visit, experts and organizing committee representatives toured the energy storage technology exhibition hall and R&D testing platform, gaining firsthand insight into the company's technological strengths and product advantages.

At the symposium, the senior engineer presented an overview of the company's development. Leveraging its leading production capacity, mature core technologies, and deep strategic collaboration with UK-based EPS (a global leader in phase-change energy storage technology), Mayer Technology has established the world's most comprehensive application portfolio across various scenarios. The company specializes in three core sectors: central air conditioning, cold storage and cold chain logistics, and smart agriculture. Its projects include landmark domestic and international initiatives such as the Qatar World Cup Stadium, Singapore's T2 Terminal, the renovation of China Tobacco's Modi Workshop, China's first long-range phase-change cold storage vehicle, waste heat recovery systems for AI data centers nationwide, and zero-carbon smart agricultural parks.

Numerous large-scale application cases have conclusively demonstrated that the company's phase-change energy storage technology boasts strong stability and significant economic benefits, delivering three core advantages: peak shaving and valley filling, scientific temperature control, and cost reduction with efficiency improvement. These features align perfectly with China's national green and low-carbon development strategy and renewable energy substitution initiatives. Experts at the conference highly recognized the company's innovative achievements and growth potential, providing professional guidance on industrial chain collaboration and core technology upgrades.

This survey serves as an authoritative recognition of Mayer Technology's innovation capabilities and industrialization achievements. Moving forward, Mayer Technology will leverage this platform to deepen upstream and downstream collaborations, contributing to the establishment of a new ecosystem for the new materials industry in the Guangdong-Hong Kong-Macao Greater Bay Area, thereby injecting strong momentum into the industry's high-quality development and the realization of China's "dual carbon" goals.
