Shanghai Haiyouwei New Materials

Shanghai Haiyouwei New Materials Co., Ltd. (HIUV), founded in 2005, operates as a high-tech enterprise centered on polymer film technology. The company, led by legal representative Li Min, focuses on the research, development, and manufacturing of advanced film materials for a diverse client base. HIUV successfully went public on the Shanghai Stock Exchange's STAR Market on January 22, 2021, under the stock code 688680. The initial public offering raised a total of 1.469 billion yuan.

The company's core business involves providing specialized polymer film products, associated technical services, and complete solutions to various industries. Its primary market is the solar photovoltaic (PV) sector, where it has established itself as a significant supplier of encapsulation materials. HIUV's product portfolio for the PV industry includes high-quality Ethylene-Vinyl Acetate (EVA) films engineered to be resistant to Potential Induced Degradation (PID) and snail trails, white pre-crosslinked EVA films for single-glass modules, and co-extruded Polyolefin Elastomer (POE) films for various types of solar cells like PERC, N-type TOPCon, and HJT. These products function as essential encapsulants for solar modules, protecting the photovoltaic cells and enhancing their performance and longevity.

Expanding beyond solar energy, HIUV has ventured into the new energy vehicle and high-end construction markets. For the automotive industry, the company supplies products like liquid crystal smart tinting films which offer features such as privacy protection, noise reduction, and energy savings. It also produces an environmentally friendly POE-based lightweight leather alternative, AXPO, designed for intelligent vehicle cabins. In the construction sector, HIUV has developed flame-retardant, high-strength PVE interlayer films for glass curtain walls, which provide excellent low-temperature impact resistance and stable adhesion. The business generates revenue from the sale of these specialized film products and by providing technical support. With a global strategy, HIUV has production bases in China and Vietnam and is exploring international joint ventures and partnerships, including plans for a factory in the United States.
