Introduction
Qingdao Zhongkehualian Advanced Materials Corp., Ltd. (青岛中科华联新材料股份有限公司) is a Chinese advanced materials and equipment manufacturer based in Qingdao’s West Coast New Area, Shandong Province. The company was founded in 2011 and is best known for developing, manufacturing, and selling complete production lines for wet-process lithium-ion battery separators, while also extending its technology platform into related high-performance film and membrane materials such as BOPET film, PI separators, PEM membranes, and UHMWPE fiber-related equipment.
In the plastics and new materials ecosystem, Zhongkehualian occupies a specialized position as an equipment integrator rather than a conventional polymer processor. Its core value lies in providing turnkey automated production-line solutions that cover process design, equipment supply, installation, commissioning, technical training, and after-sales support for separator and film production projects. This combination of mechanical engineering, process know-how, and advanced polymer materials technology has made the company relevant to the rapid expansion of battery materials manufacturing in China and abroad.
The company’s development has been closely tied to the rise of the lithium-ion battery separator industry. It reported a successful test run of its first separator demonstration line in 2013, and in 2014 its “lithium-ion battery separator production line and supporting process” was recognized as a domestically first-of-its-kind major technical equipment in China. Zhongkehualian later broadened its industrial footprint through separator-related production assets and, by the mid-2020s, became associated not only with production equipment but also with separator manufacturing capacity through affiliated operations.
History and Development
Zhongkehualian was established on 11 November 2011 in Qingdao. From its early years, the company concentrated on wet-process separator equipment, a field that requires precise control over extrusion, casting, stretching, extraction, drying, and winding operations.
Key milestones in its development include:
- 2013: the company’s first lithium battery separator demonstration line was successfully commissioned.
- 2014: its separator production line and supporting process were identified as a major technical equipment achievement in China.
- 2015–2016: the company completed its shareholding-company transformation and entered the public markets through the New Third Board, reflecting its transition from a private equipment developer to a more formalized industrial technology enterprise.
- 2018: the company ended its New Third Board listing, while continuing to focus on separator equipment and related advanced-materials projects.
By the early 2020s, the company had expanded beyond single-line equipment supply into broader industrial development, including demonstration lines, production bases, and research-oriented projects connected with separator materials and adjacent membrane technologies.
