Introduction
CHINASUN SPECIALTY PRODUCTS CO., LTD., known in Chinese as 江苏强盛功能化学股份有限公司, is a Chinese manufacturer of organic peroxides and chemical reagents headquartered in Changshu, Jiangsu, in the Changshu New Material Industrial Park. Founded in 1997, the company is a listed enterprise on China’s NEEQ market under stock code 831184, and it describes itself as a high-technology manufacturer integrating research, production, sales, and technical services. In the plastics and rubber materials chain, the company is best understood as a specialty chemical supplier whose peroxide products are used as initiators, cross-linking agents, vulcanizing agents, and polymer modification additives.
Within the broader plastics industry ecosystem, Chinasun occupies a niche linked to polymer processing and compounding, rather than primary resin production. Its products are used in applications such as silicone rubber cross-linking, EPDM and polyethylene cross-linking, and polypropylene degradation, making it relevant to manufacturers of rubber goods, modified plastics, and related industrial materials. Company and third-party listings also indicate that it has developed export activity and serves customers outside China, supporting its position as a specialty supplier with international reach.
History and development
Chinasun’s development began in 1997, when the company was established as a private enterprise and gradually expanded from a small initial capital base into a specialty chemicals producer. Company materials describe an early entrepreneurial phase in which its founder built the business through trade and then moved into manufacturing, with later emphasis on technical transformation and process modernization.
A major milestone came in 2014, when the company was admitted to China’s National Equities Exchange and Quotations (NEEQ) system, marking its transition to a publicly listed small- and medium-sized enterprise. The listing also appears in company and market databases under the stock abbreviation Chinasun and code 831184.
A further development theme has been capacity expansion and process upgrading. Company descriptions state that Chinasun has built multiple organic peroxide production lines and adopted continuous production technology and automated line operation, with the aim of improving quality, cost competitiveness, and supply reliability.
Business operations
Chinasun’s core business is the R&D, production, and sales of organic peroxides, alongside the packaging and sales of chemical reagents. Its official descriptions emphasize a business model combining manufacturing with technical service, rather than a pure distribution role.
Key operational characteristics include:
- Specialty chemical manufacturing focused on peroxide chemistry.
- Technical services and customer support for differentiated applications.
- Export-oriented supply capability, with trade records indicating shipments to overseas buyers.
- Manufacturing base in Jiangsu, a region with dense chemical and materials-industry infrastructure.
The company’s disclosed headquarters and office address is No. 18, Haiwang Road, Changshu New Material Industrial Park, Jiangsu Province.
Products and technologies
Chinasun’s product portfolio centers on organic peroxides, a class of compounds widely used in polymer processing because they decompose to form radicals that initiate or modify chemical reactions in polymers. Public product pages identify specific peroxide grades and associated performance characteristics.
Representative product examples include:
- Enox DCBP: described as a diacyl organic peroxide used as a vulcanizing agent for extruded silicone rubber, producing materials with high strength and good transparency.
- Enox 101-60D-pd: identified as 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane, a peroxide used mainly for silicone rubber cross-linking.
- Enox 101-94: a low-volatility peroxide grade used as a cross-linking agent for polymers such as silicone rubber, EPDM, and polyethylene, and also for polypropylene degradation.
From a plastics-processing perspective, these products matter because organic peroxides are used to:
- Cross-link elastomers and polyolefins
- Control melt properties in polyolefin modification
- Support heat resistance and mechanical performance in finished materials
- Enable specialized rubber processing routes where thermal stability and curing behavior are critical
Company materials also indicate a focus on automated production lines and continuous production technology, which is significant in peroxide manufacturing because these substances require careful control of temperature, purity, and safety conditions.
Applications and end markets
Chinasun’s products are used in sectors that depend on polymer modification and rubber processing, including:
- Silicone rubber
- EPDM rubber
- Polyethylene processing
- Polypropylene modification
- General polymer cross-linking applications
These applications place the company in the supply chain for industrial materials used in:
- Electrical insulation and wire-related materials
- Seals, hoses, and elastomeric components
- Foam and specialty polymer products
- Modified thermoplastics and rubber compounds
Because organic peroxides are performance additives rather than bulk polymers, Chinasun’s commercial role is tied to formulation expertise, customer-specific grades, and process consistency rather than commodity-scale output.
Global presence and market position
Available public sources describe Chinasun as serving customers around the world and collaborating with international chemical companies, although detailed share data are not publicly disclosed in the materials reviewed. Export records and third-party shipment databases suggest that the company has established cross-border trade activity.
Industry-directory sources characterize the company as a manufacturer of organic peroxides and specialty chemicals, and some market listings reference scale in the peroxide segment, including a reported annual capacity figure for one peroxide product line in a market report. Because those figures are product-specific and not fully independently audited in the available materials, they should be treated cautiously as indicative rather than definitive.
The company’s market position is therefore best described as a specialized mid-sized peroxide producer with a focus on customized products for polymer-processing customers.
Sustainability and environmental management
Publicly available information on Chinasun’s sustainability strategy is limited, but several aspects of peroxide manufacturing are inherently relevant to environmental and safety management. Organic peroxide production is a regulated, process-sensitive business that typically requires strict control of hazardous materials, waste handling, and transport conditions.
Company-affiliated information indicates that the group has published environmental management information for one of its subsidiaries, reflecting at least some formal attention to hazardous waste pollution prevention and control. In addition, the company’s move toward automated and continuous production is consistent with industry efforts to improve process efficiency and operational control, which can also support safer and more stable manufacturing.
Leadership and corporate governance
Public filings and market databases identify Yi Li (应立) as chairman and legal representative, with Tang Mingliang (唐明亮) listed as general manager and board secretary in reporting materials. Ownership disclosures in market data indicate that the company is controlled by Ying Zhiyao (应志耀) and Yi Li (应立).
The company is organized as a publicly listed Chinese specialty chemicals manufacturer, with governance disclosures available through NEEQ-related filings and company announcements.
Innovation and future outlook
Chinasun’s stated development path emphasizes technological innovation, customer-specific solutions, and continuous improvement in peroxide manufacturing. Its participation in national and industry standards, as described in third-party company profiles, suggests an effort to shape and comply with technical norms in peroxide chemistry.
Looking ahead, the company’s prospects are likely to remain linked to several industry trends:
- Demand for advanced rubber and polymer modification chemicals
- Greater use of customized peroxide grades for specialized formulations
- Ongoing emphasis on production safety and process automation
- Potential growth in export markets for specialty intermediates and additives
Its long-term competitiveness will depend on its ability to maintain product consistency, regulatory compliance, and technical service capability in a market where specialty chemical suppliers are judged heavily on reliability and application performance.
