Introduction
Zhejiang Qintang Calcium Industry Co., Ltd. (浙江钦堂钙业有限公司) is a Chinese calcium carbonate producer based in Jiande, Hangzhou, Zhejiang Province, with business centered on the mining, processing, and development of ground calcium carbonate and related non-metallic mineral materials. The company was founded in 2008 and describes itself as a large-scale regional producer integrating mineral extraction, powder processing, and new-material R&D, with reported annual capacity of 1 million tonnes of calcium carbonate powder in grades ranging from 200 mesh to 3000 mesh.
In the plastics and polymers supply chain, the company is relevant as a mineral filler and functional additive supplier, serving applications such as plastic products, pipes, wire and cable, plate materials, adhesives, coatings, paper, inks, rubber, and artificial leather. Its product profile and patent activity indicate an emphasis on particle-size control and powder filling compounds, which are important for stiffness, processability, cost reduction, and surface performance in polymer formulations.
History and Development
Zhejiang Qintang Calcium Industry was established on 5 September 2008 in Qintang Township, Jiande, an area identified by the company as part of East China’s heavy calcium carbonate base. Its business has since expanded from mineral processing into a broader materials platform that includes mining, powder grinding, and new-material development.
A major structural feature of the company is its self-owned green mine, reported to cover about 0.5 square kilometres, providing an upstream raw-material base for its powder operations. The company also reports a production campus of 125,000 square metres with 90,000 square metres of buildings and multiple workshops.
A later administrative development was the company’s name change from Zhejiang Qintang Calcium Industry Co., Ltd. to Zhejiang Qintang Calcium Industry Co., Ltd. in its corporate filing history as reflected in official and third-party records; an innovation-related government notice also lists the updated legal name Zhejiang Qintang Calcium Industry Co., Ltd. under a high-tech enterprise record.
Business Operations and Segments
The company’s operations appear to be organized around three linked activities:
- Mining and raw-material supply through its own limestone resource base.
- Grinding and classification of calcium carbonate powders across a wide fineness range.
- New-material development, including downstream compound and filler-related applications.
Its registered business scope includes non-metal mineral products manufacturing and sales, plastic products manufacturing and sales, chemical product manufacturing and sales excluding licensed chemicals, building-material sales, building stone processing, and import-export activity. This scope is consistent with a supplier positioned between upstream mineral extraction and downstream industrial end users.
The company is also referenced in industry-ranking and exhibitor contexts as a notable calcium carbonate enterprise in China.
Products and Technologies
Zhejiang Qintang’s core product family is calcium carbonate powder, particularly ground calcium carbonate (GCC) produced in a range of particle sizes from 200 mesh to 3000 mesh. The company states that it offers a broad mix of lower-, medium-, and higher-grade products for customized industrial use.
Key technical and product features include:
- QT-1 series products, subdivided by fineness into 4th, 5th, 6th, and 7th grade sand categories, with particle sizes reportedly ranging from 10 mesh to 200 mesh.
- Fine powder grades for uses requiring tighter particle-size control and improved dispersion characteristics in formulations.
- Packaged supply options including ton bags and 50 kg bags, which are standard in industrial bulk mineral logistics.
The company’s patent record shows a filing for a high-mesh powder-filled masterbatch and preparation method, suggesting involvement in polymer additive formulation and compatibility with plastics compounding. In practical terms, high-mesh calcium carbonate can be used as a filler in plastics to influence stiffness, surface feel, cost structure, and processing behavior, depending on resin system and surface treatment.
Applications and End Markets
The company identifies a wide set of industrial applications for its calcium carbonate products. These include:
- Plastics
- Pipes
- Wire and cable
- Plate and sheet materials
- Adhesives and sealants
- Coatings and paints
- Paper
- Inks
- Rubber
- Artificial leather
- Construction materials
For the plastics sector specifically, calcium carbonate is commonly used as a functional filler and cost modifier in rigid PVC, masterbatch, and other polymer systems. Zhejiang Qintang’s reported patent on filler masterbatch aligns with this downstream market orientation.
Global Presence and Market Position
Available sources indicate that the company is primarily a domestic Chinese producer with industrial relevance in the East China calcium carbonate cluster. The company’s export activity is permitted by its registered business scope, but the available sources do not provide reliable shipment volumes or a verified country-by-country export profile.
Industry listings and rankings place Zhejiang Qintang among notable Chinese heavy calcium carbonate producers. A market report also identifies the company as a significant participant in the calcium carbonate industry, though the report excerpt available here does not provide audited financial detail.
Sustainability and Environmental Initiatives
The company presents its mine as a green mine, which indicates attention to resource-management and environmental positioning in a sector often scrutinized for quarrying impacts. That said, the available sources do not provide detailed public data on emissions, energy intensity, water reuse, or life-cycle assessment.
More broadly, its business model reflects several industry sustainability considerations:
- Local mineral sourcing, which can reduce transport distance for domestic customers.
- Bulk mineral substitution in plastics, where calcium carbonate can sometimes replace a portion of higher-cost resin content, improving material efficiency.
- Packaging options that support industrial logistics and reduce handling losses.
Financial Performance and Economic Impact
Publicly available sources in the provided material do not disclose full audited revenue, profit, or margin data for the company. The firm’s significance appears to rest more on production scale, asset base, and industry position than on published financial reporting.
Its economic role is tied to:
- The non-metallic minerals value chain in Zhejiang Province.
- Supply to plastics, coatings, paper, and construction-related industries.
- Employment and industrial activity associated with its multiple workshops and mining-linked operations.
Leadership and Corporate Governance
Corporate records list Wu Pengjian as legal representative, with the company registered in Jiande City Market Supervision Administration. The company’s official filings also identify it as a high-tech enterprise in a Zhejiang government notice, indicating recognition under China’s technology enterprise framework.
The available sources do not provide a detailed public board structure, executive team profile, or ownership breakdown sufficient for a fuller governance analysis.
Innovations and Future Outlook
Zhejiang Qintang’s innovation profile is centered on particle engineering, powder processing, and downstream filler applications. The patent record suggests interest in higher-value materials used in plastic compounding, which may support deeper participation in engineered-filler markets rather than commodity-only supply.
Likely future priorities for a company in this position include:
- Further development of fine and ultra-fine calcium carbonate grades.
- Expanded use in polymer masterbatch and compound formulations.
- Continued emphasis on resource efficiency and green quarry management.
- Potential growth in customized industrial powders for plastics, coatings, and construction materials.
Summary
Zhejiang Qintang Calcium Industry is a Zhejiang-based calcium carbonate manufacturer with integrated mining and powder-processing capabilities, a sizeable production base, and a product portfolio that reaches deeply into the plastics and industrial materials supply chain. Its role in the plastics sector is primarily that of a mineral filler and compound-material supplier, supported by a broad range of particle sizes, industrial packaging formats, and patent activity in filler masterbatches.
