Inner Mongolia Shuangxin Environment-Friendly Material Co., Ltd. is a high-tech enterprise specializing in the research, development, production, and sales of products across the polyvinyl alcohol (PVA) industrial chain. Its portfolio includes PVA, specialty PVA fibers, vinyl acetate (VAC), and calcium carbide (also known as electric stone), enabling a fully integrated layout from upstream raw materials to downstream applications. Calcium carbide serves as a foundational material for producing acetylene, which is essential for synthesizing chemicals like PVC, PVA, and BDO in organic chemistry. PVA, a water-soluble and biodegradable polymer, offers properties such as adhesion, fiber-forming, emulsion stability, gas barrier effects, film-forming, and biodegradability, finding use in industrial additives, adhesives, safety glass interlayer films (PVB films), water-soluble films, and optical films. The company impacts sectors including fine chemicals, green construction, papermaking, textiles, automotive, biodegradable packaging, optoelectronics, and pharmaceuticals, aligning with state-supported new materials development. Recently listed on the main board following an IPO of 287 million shares aimed at raising up to RMB 1.97 billion, proceeds fund expansions in PVB resin and film, water-based adhesives, energy-saving transformations, R&D centers, and working capital. With audited net profits of RMB 803 million (2022), RMB 526 million (2023), RMB 485 million (2024), and RMB 269 million (H1 2025), it demonstrates steady operational performance in the coal chemical and advanced materials markets.
