परिचय

Jiangsu Shenlong Zinc Industry Co., Ltd. (江苏申隆锌业有限公司) is a privately held Chinese chemical manufacturer specializing in zinc-based functional materials for कोटिंग्स, plastics, rubber, electronics, pharmaceuticals, ceramics, cosmetics, and related industries. Established in 1996, the company is based in Dainan, Xinghua City, Jiangsu Province, an industrial locality associated with stainless-steel manufacturing. Its activities combine research and development, production, quality management, and domestic and international sales.

The company’s portfolio includes zinc powder, flake zinc powder, जिंक ऑक्साइड, zinc phosphate, aluminum tripolyphosphate, zinc borate, ethylene bis(stearamide) (EBS), zinc stearate, zinc molybdate, zinc chloride, basic zinc carbonate, and anti-corrosion or anti-mold additives. In the plastics industry, these materials function primarily as additives, stabilizing agents, fillers, processing aids, pigments, and performance-enhancing components rather than as base polymers.

Shenlong Zinc occupies an intermediate position in the plastics value chain. It supplies specialized inorganic and organic additives to compounders, coating formulators, rubber processors, plastics manufacturers, and other downstream users. Its strategic significance derives from the increasing need for corrosion protection, flame retardancy, antimicrobial performance, processing efficiency, regulatory compliance, and consistent batch quality in formulated materials.

History and Development

The company was founded in Dainan in 1996 as a producer of zinc products. Its subsequent development followed the broader transformation of China’s chemical-materials sector, in which specialized manufacturers increasingly combined production with application-oriented research and technical service.

Important development milestones include:

• 1996: Establishment of the company in Dainan, Jiangsu Province.
• 2015: Adoption of ISO 9001 quality-management and ISO 14001 environmental-management certifications, according to company information.
• Later expansion: Development of a Shanghai branch and plans for a new facility in Jiangxi, supporting wider domestic coverage and international business development.
• International regulatory development: Registration of जिंक ऑक्साइड and zinc phosphate products under the European Union’s REACH framework.
• 2026: Registration as an active participant in the United Nations Global Compact, identifying the company as a Chinese small or medium-sized enterprise in the chemicals sector.

The company’s development reflects a shift from supplying basic zinc chemicals toward offering a broader range of formulated and application-specific materials for industrial users.

Business Operations and Segments

Shenlong Zinc integrates three principal activities:

• Manufacturing: Production of zinc-based powders, oxides, phosphates, borates, lubricants, and related specialty chemicals.
• Research and development: Technical work supporting product consistency, particle characteristics, formulation suitability, and application performance.
• Sales and distribution: Domestic sales through offices and commercial channels in several major Chinese industrial regions, together with exports to overseas markets.

The company reports more than one hundred employees, with approximately one-fifth engaged in quality or technical functions. It also operates a research and development center and describes its production process as traceable across the manufacturing chain.

Its operating model is closely connected to the needs of downstream formulators. Rather than supplying a single commodity product, the company serves multiple material systems in which the form, purity, particle size, surface characteristics, and dispersion behavior of an additive can affect final-product performance.

Products and Technologies

Zinc powder and flake zinc powder

Zinc powder is used in anti-corrosion coatings, including systems applied to steel structures, ships, containers, fasteners, and industrial equipment. Zinc-rich coatings provide cathodic protection by allowing zinc to corrode preferentially to the underlying steel.

Flake zinc powder is associated particularly with thin-film anti-corrosion systems and zinc-flake coatings. Compared with conventional spherical particles, flake-shaped particles can form overlapping barrier structures that improve coating compactness and reduce the pathways available for moisture and corrosive agents.

Relevant technical considerations include:

• Particle-size distribution and morphology
• Zinc purity and surface oxidation
• Dispersion in resin or coating systems
• Packing density and orientation within the coating
• Compatibility with waterborne or solvent-based formulations

जिंक ऑक्साइड

जिंक ऑक्साइड is a multifunctional inorganic material used in rubber vulcanization, plastics, coatings, ceramics, pharmaceuticals, cosmetics, electronics, and other applications. In rubber compounds, it participates in the vulcanization system, while in plastics it may function as an activator, stabilizer, pigment, or functional additive depending on the polymer and formulation.

The company identifies both environmentally oriented जिंक ऑक्साइड and pharmaceutical-grade जिंक ऑक्साइड among its products. Product suitability depends on factors such as purity, heavy-metal control, particle size, surface area, moisture content, and compliance with application-specific regulatory requirements.

Zinc phosphate and phosphate compounds

Zinc phosphate is widely used as an anti-corrosion pigment in primers and protective coatings. It can help inhibit corrosion at the metal–coating interface and is often incorporated into systems designed to reduce reliance on older chromate-based technologies.

Shenlong also produces aluminum tripolyphosphate and related phosphate materials. These compounds are relevant to protective coatings, primers, pigments, and selected polymer or composite formulations in which inorganic phosphate chemistry contributes to corrosion resistance or flame-retardant performance.

Zinc borate

Zinc borate is used in plastics, rubber, coatings, and other materials as a multifunctional additive. Depending on grade and formulation, it can contribute to flame retardancy, smoke suppression, char formation, and antifungal performance. Its effectiveness depends on polymer type, loading level, particle dispersion, and interaction with other flame-retardant components.

EBS and metal stearates

Ethylene bis(stearamide), commonly known as EBS, is an organic processing aid and lubricant used in plastics, masterbatches, coatings, inks, and powder-processing applications. It can reduce friction, improve release, assist pigment dispersion, and support surface finish.

Zinc stearate is used as a lubricant, mold-release aid, stabilizing component, and hydrophobic additive in plastics, rubber, coatings, and related formulations. Its performance is influenced by particle size, acid value, moisture, thermal behavior, and compatibility with the host material.

Other zinc-based products

The company’s broader catalogue includes zinc molybdate, zinc chloride, basic zinc carbonate, anti-corrosion additives, and anti-mold agents. These products serve more specialized roles, including corrosion inhibition, chemical processing, rubber and plastics compounding, surface treatment, and preservation-oriented formulations.

Applications and End Markets

Shenlong Zinc’s products are used across several interconnected industrial sectors:

The company’s presence in these markets illustrates the way zinc chemistry links plastics manufacturing with coatings, rubber processing, metal protection, and specialty chemicals. A single material, such as जिंक ऑक्साइड, may serve substantially different functions depending on particle characteristics and formulation design.

Global Presence and Market Position

The company operates from Jiangsu and maintains a Shanghai branch, while company information identifies offices or commercial presence in Zhejiang, Shandong, and Guangdong. These locations correspond to major Chinese manufacturing and export corridors serving plastics, coatings, rubber, electronics, and chemical-processing customers.

Internationally, Shenlong Zinc supplies overseas markets and has pursued REACH registration for जिंक ऑक्साइड and zinc phosphate. Such registration can facilitate access to European markets by addressing substance-registration requirements applicable to covered chemical products.

The company exhibited through the CHINAPLAS eMarketplace within the plastics and rubber segment, positioning its materials as inputs for processors and formulators rather than as finished plastic products. Its competitive position is therefore shaped by:

• Product breadth across zinc chemicals and formulation additives
• Ability to supply both standard and application-specific grades
• Regulatory documentation for international customers
• Technical support for plastics, rubber, and coatings formulations
• Domestic distribution across several manufacturing regions
• Reliability of quality control and batch-to-batch consistency

Publicly available information does not establish a numerical market share or independently verified industry ranking. The company describes itself as a major participant in China’s zinc-products sector, but that characterization is best understood as a company-reported positioning statement rather than a quantified market measurement.

Research and Development

Research and development at Shenlong Zinc is directed toward product consistency, process control, and suitability for downstream formulations. The company reports a modern research center and a technical and quality workforce representing approximately 20 percent of its employees.

For plastics and rubber applications, relevant development priorities include:

• Control of particle size and particle morphology
• Improved dispersion in polymer matrices
• Reduction of agglomeration during compounding
• Stable thermal and chemical behavior
• Compatibility with resin systems and processing temperatures
• Development of grades with lower environmental or regulatory burdens
• Consistent performance across production batches

The technical requirements of zinc additives vary considerably. जिंक ऑक्साइड for rubber, for example, is evaluated differently from जिंक ऑक्साइड intended for pharmaceutical, cosmetic, electronic, or plastics applications. This creates a need for differentiated specifications, controlled impurities, and application-specific quality testing.

Sustainability and Environmental Initiatives

The company maintains ISO 14001:2015 environmental-management certification and identifies environmentally oriented जिंक ऑक्साइड and zinc powder products within its portfolio. It also describes measures involving reduced use of hazardous chemicals and resource recycling in connection with its manufacturing approach.

The company’s sustainability profile includes several dimensions:

• Environmental-management systems based on ISO 14001
• Development and marketing of products described as environmentally friendly
• Resource-recycling practices
• Regulatory registration for selected products in international markets
• Occupational-health and safety management under ISO 45001

Zinc-based additives can support environmental improvements in downstream products, particularly where they replace chromate-containing corrosion-control systems or contribute to longer service life. At the same time, zinc compounds remain subject to careful management because zinc releases can affect aquatic environments and occupational exposure must be controlled during powder handling and processing. The environmental performance of a zinc-containing product therefore depends on the full life cycle, including raw-material sourcing, manufacturing, formulation, use, recovery, and disposal.

Quality Management and Certifications

Shenlong Zinc reports certification to three major management-system standards:

• ISO 9001:2015: Quality-management systems
• ISO 14001:2015: Environmental-management systems
• ISO 45001:2018: Occupational health and safety management systems

The company also states that its जिंक ऑक्साइड and zinc phosphate products have completed registration under the EU REACH regulation. These registrations are particularly relevant to customers exporting coatings, plastics compounds, rubber products, and other formulated goods into European markets.

Quality control for zinc powders and additives commonly involves monitoring chemical composition, particle-size distribution, moisture, bulk density, morphology, surface properties, and contaminant levels. The company’s stated emphasis on traceability and technical staffing is consistent with the quality demands of industrial customers that require stable processing behavior and reproducible finished-product performance.

Economic and Industrial Significance

Shenlong Zinc contributes to the plastics industry as an upstream supplier of functional additives rather than as a producer of polymers or finished plastic articles. Its products can influence processing efficiency, durability, corrosion resistance, flame performance, surface quality, and regulatory suitability.

Its economic role is connected to several structural trends:

• Expansion of protective coatings for infrastructure, transportation, marine equipment, and containers
• Demand for longer-lasting plastic and rubber products
• Growth of additive-intensive polymer formulations
• Replacement of certain legacy corrosion-control chemistries
• Greater emphasis on traceability and regulatory documentation
• Diversification of Chinese specialty-chemical supply chains
• Internationalization of domestic materials manufacturers

The planned Jiangxi expansion, together with the existing Jiangsu base and Shanghai branch, indicates an effort to strengthen manufacturing capacity and geographic coverage. The company’s participation in the United Nations Global Compact further places it within a broader framework of corporate sustainability and responsible-business commitments.

Innovations and Future Outlook

Future development is likely to depend on the company’s ability to combine zinc chemistry with increasingly demanding requirements from plastics and related industries. Important areas include:

• Lower-emission and lower-hazard corrosion-protection systems
• Fine-particle and surface-treated additives for advanced polymer compounds
• Improved zinc-utilization efficiency in rubber and plastics
• Halogen-free or multifunctional flame-retardant packages
• Additives compatible with recycled and bio-based polymers
• Higher levels of digital traceability and process monitoring
• Expanded regulatory support for international customers
• Technical collaboration with compounders, coating manufacturers, and processors

The main strategic challenge is balancing product performance with environmental, health, safety, and regulatory expectations. Zinc materials can extend product life and replace some more hazardous chemistries, but their manufacture and end-of-life behavior require responsible control. Continued investment in application research, quality systems, regulatory compliance, and resource efficiency will therefore be important to the company’s competitiveness.
