The company is reported to run five production lines with annual capacity cited at 80,000 to 100,000 tonnes, depending on the source and reporting context. Its product portfolio includes more than 30 types of fine carbon black and SDW-series specialty grades, including materials for plastic, conductive, ink, and fiber applications. Public records describe Starwin as a technology-oriented enterprise that has expanded from trading into manufacturing, with investments in research, environmental systems, and specialized carbon black production lines.
History and Development
Starwin was established in 2014 according to local government records, although some industry listings refer to a 2003 origin for the broader Starwin business name; the most credible, company-specific local records identify the Wenshui manufacturing entity as a 2014-founded producer. From 2014 to 2017, the company primarily operated in trading and sales, then shifted into manufacturing from 2018 onward through acquisition and new construction.
Key development milestones reported by local authorities include:
- The build-out of five carbon black lines, including two 2,500-ton ink carbon black lines, one 15,000-ton conductive carbon black line, and two 30,000-ton lines for plastic fiber and negative-material carbon black.
- Recognition as a high-tech enterprise in 2018, later followed by provincial and national specialized, sophisticated, distinctive, and innovative enterprise designations.
- Establishment of a provincial enterprise technology center in 2020 and continued inclusion in government-supported innovation and industrial lists in 2024.
Business Operations and Segments
Starwin’s core business is the production and sale of specialty carbon black for industrial use, with a focus on downstream sectors that require controlled particle characteristics and performance consistency. Its operations are concentrated in Shanxi Province, where the company benefits from proximity to coal-tar-related raw materials and industrial transport links, as noted in company descriptions.
The company’s business can be understood in three practical segments:
- Manufacturing of specialty carbon black grades
- R&D and product development for new carbon-based materials
- Sales and export, including a reported self-operated export right and a diversified customer base
Local government reporting states that the company had 262 employees, including 37 R&D personnel, which suggests a manufacturing model with a relatively strong technical staffing profile for a mid-sized industrial materials producer.
Products and Technologies
Starwin produces a range of fine carbon black products used in plastics, conductivity, paints, inks, coatings, rubber, dyeing, chemical fiber, and battery-related materials. The company states that it has developed more than 20 SDW-series carbon-based new products, while local records describe a portfolio adapted to several specialized application fields.
Reported product and process capabilities include:
- Ink carbon black for high-color-strength and dispersion-oriented uses
- Conductive carbon black for antistatic and electrically conductive formulations
- Plastic and chemical-fiber carbon black for coloration and UV-related performance needs
- Negative-material carbon black used in battery-related and energy-material applications
The company’s production configuration includes both 槽法 and 炉法 carbon black lines, with the latter supporting larger-volume specialty grades. Local reporting also notes supporting utilities such as tail-gas power generation, wastewater treatment, desulfurization, and denitrification systems, indicating an integrated manufacturing setup with pollution-control infrastructure.
Applications and End Markets
Starwin’s products serve end markets where carbon black is used as a functional additive rather than only as a pigment. The principal application areas reported for the company are:
- Plastics and polymer compounding
- Rubber and tire materials
- Coatings and paints
- Printing inks
- Chemical fibers
- Conductive and battery-material formulations
In plastics, specialty carbon black is typically used to provide black coloration, UV resistance, conductivity, and mechanical reinforcement, depending on grade and loading. Starwin’s product mix indicates participation in this broader polymer-additives market, especially where customers need consistent dispersion and controlled performance characteristics.
Global Presence and Market Position
Starwin presents itself as a supplier with a diversified domestic market and a degree of export capability. Public listings and exhibition records show the company participating in industry platforms such as CHINAPLAS, which suggests an active effort to reach plastics and materials customers beyond its home region.
The company is not described in the available sources as a global commodity-scale producer; rather, it appears to occupy a specialty and regional industrial materials position with a focus on fine carbon black grades and tailored application performance. Its market standing is reinforced by repeated recognition in Chinese innovation and “specialized, sophisticated” enterprise programs.
Sustainability and Environmental Initiatives
Available records indicate that Starwin has invested in environmental infrastructure alongside capacity expansion. Local government documentation specifically mentions:
- Wastewater treatment capacity
- Desulfurization equipment
- Denitrification systems
- Tail-gas power generation for resource recovery
These measures align with the regulatory realities of carbon black manufacturing, which is energy-intensive and emissions-sensitive. The public materials suggest the company has positioned these systems as part of a green circular-economy chain, although detailed independently verified emissions data were not available in the sources reviewed.
Financial Performance and Economic Impact
Local government reporting for 2022 states that Starwin recorded RMB 453 million in sales revenue, RMB 397.35 million in total profit, RMB 676.57 million in taxes and fees, and total assets of RMB 229 million. The same source also describes an annual output value of around RMB 400 million and places the company among the significant industrial employers in its local development zone.
The company’s economic impact is most visible at the regional level in Shanxi, where it contributes to:
- Industrial employment
- Local tax revenue
- Demand for logistics, utilities, and raw materials
- Technology-led manufacturing upgrading in specialty carbon materials
Leadership and Corporate Governance
Publicly available records identify Zhao Wenjun as the legal representative of the Wenshui-based company, with other local filings also listing Li Yalong as a responsible contact in government materials. A contact page on the company website lists Steven Shen as a business contact for the broader Starwin web presence.
The company appears to combine private ownership with government-recognized innovation credentials, including high-tech and specialized-enterprise status, which suggests a governance model centered on manufacturing discipline, technical development, and compliance with industrial certification requirements.
Innovations and Future Outlook
Starwin’s development trajectory suggests continued emphasis on specialty-grade carbon black, particularly for applications where performance differentiation matters more than commodity volume. Its technical center recognition and ongoing product expansion indicate a strategy built around:
- New specialty grades for plastics and conductive materials
- Process optimization across ink, fiber, and battery-related uses
