PVP/VA Copolymer, also known as copovidone, is a functional polymer synthesized from N-vinyl-2-pyrrolidone (NVP) and vinyl acetate. Owing to its excellent film-forming ability, binding strength, solubility, and formulation compatibility, it is widely used in pharmaceutical solid dosage forms, cosmetic formulations, and personal care products. Typical applications include tablet binders, granulation aids, controlled-release matrices, and styling polymers in hair and skin care products.Driven by the steady growth of pharmaceutical excipients and high-end cosmetic raw materials, China has developed a mature manufacturing base for PVP and related copolymers. Several Chinese manufacturers now possess complete capabilities ranging from polymer synthesis and purification to quality control and global supply. The following companies represent the most established and competitive PVP/VA copolymer manufacturers in China today.
Huzhou Sunflower Pharmaceutical Co., Ltd.
Huzhou Sunflower Pharmaceutical Co., Ltd. is widely recognized as one of China's leading manufacturers of PVP-based polymers and functional copolymers, with deep roots in the country's early PVP industrialization. Originating from the establishment of Zhejiang Sunflower New Materials in the early 1990s, the company has built more than three decades of technical expertise in NVP polymerization and downstream product development. Led by Professor-level senior engineer Wu Jiaxiang, a pioneer of China's PVP technology, Sunflower has continuously advanced the industrial production and application research of povidone and its derivatives since the late 1970s. Its PVP/VA Copolymer products, marketed under the Sunvidone® series, comply with major international pharmacopoeial standards including USP/NF, Ph. Eur., and JP, making them suitable for pharmaceutical applications such as tablet binders, dry binders, wet granulation agents, film formers, and functional excipients in modified-release systems. Located in Huzhou, Zhejiang Province, within the highly developed Yangtze River Delta industrial region, the company benefits from a strong upstream and downstream supply chain. Sunflower operates multiple GMP-compliant production lines covering low-, medium-, and high-molecular-weight PVP, PVP/VA copolymers, povidone iodine, and other functional materials, with annual production capacity reaching several thousand tons. Supported by ISO-certified quality management systems and comprehensive technical service capabilities, its products are supplied to pharmaceutical, cosmetic, and personal care manufacturers both domestically and internationally, with exports to Europe, the Americas, Southeast Asia, and the Middle East. Today, Sunflower stands as one of the most technically established and reliable PVP/VA copolymer suppliers in China, playing a key role in enhancing the global competitiveness of Chinese functional polymers.
