Puxijing New Energy Materials

Puxijing New Energy Materials (Shanghai) Co., Ltd. operates as a pivotal domestic supplier of ultra-high-purity polymer specialty materials, addressing a market heavily reliant on imports. Founded in late 2021 by CEO Zhang Wenlong, the company has concentrated its efforts on the independent research, development, production, and sales of high-end polyolefin materials. The firm's core product is an ultra-high-purity, high-molecular-weight polyethylene (UHMWPE), a specialized thermoplastic recognized for its high strength, toughness, and chemical resistance. This material is crucial for manufacturing lithium battery separators, specialty fiber materials, medical implants, and high-end filter materials for the semiconductor industry.

Puxijing has successfully navigated significant financing rounds, indicating strong capital market confidence in its technical capabilities and market position. In June 2025, the company secured nearly 500 million yuan (approx. $70 million) in a Series B+ financing round involving several state-owned firms and private investment companies. These funds are earmarked for completing the first-phase construction of its major production facility in the Shanghai Chemical Industry Park, team expansion, and market development. This project, recognized as a major project in Shanghai for 2024 and 2025, aims for an annual production scale of 280,000 tons upon full completion, with the first phase targeting half of that capacity and expected to commence operations in the third quarter of 2025.

The company serves a client base that includes mainstream domestic lithium battery separator enterprises, which have validated that Puxijing's products are comparable to imported equivalents in purity, consistency, and performance. Beyond lithium battery components, Puxijing is expanding its product applications to include high-end polyethylene wax and specialty packaging materials, again targeting niches with high import dependency. This strategy of using a platform-based approach to enter high-value-added markets aims to systematically fill gaps in the domestic industrial chain. The company's development is described by its founder as entering a '3.0 stage' characterized by intensive technology, talent, and capital, with a focus on materials critical to China's energy revolution and supply chain security.
