Introduction
Zhejiang Bushi New Material Co., Ltd. (浙江布石新材料有限公司) is a Chinese specialty materials manufacturer founded in 2004 and headquartered in Jiande, Hangzhou, Zhejiang Province. The company is best known as a professional producer of calcium carbonate and related alkaline materials, with operations spanning research, production, marketing, and customer service.
Within the plastics industry, the company primarily serves as a functional filler supplier, providing calcium carbonate products used in plastic compounding, as well as in papermaking, rubber, coatings, and building materials. Its product portfolio also includes calcium hydroxide and calcium oxide under the “Shiyuan” brand, including special low-lead calcium hydroxide for applications in pharmaceuticals, food-related processing, wastewater treatment, flue-gas desulfurization, incineration, coatings, building materials, and leather processing.
Bushi New Material reports more than 200 employees, three calcium carbonate production lines, and an annual output of about 200,000 tons, with an annual output value of around 120 million yuan. The company states that it has obtained the “Bushi” trademark, ISO 9001:2000 management system certification, and product conformity claims to SGS standards. ChinaPlas exhibitor information also identifies the company as a “Shining Niche” enterprise, indicating recognition as a specialized supplier within the plastics and materials ecosystem.
History and Development
Founded in 2004, the company developed in Jiande’s Hangtou Town, benefiting from access to local limestone resources and transportation links to major highways in Zhejiang Province. From its early years, it positioned itself as a materials producer combining scientific research, manufacturing, and customer-oriented customization.
A second development milestone was the expansion into a multi-line production base. Company information states that Bushi New Material built three calcium carbonate production lines and invested in domestic advanced equipment and testing instruments to support product consistency and quality control.
A third milestone is the company’s stated capacity-expansion plan. It has indicated an investment of 50 million yuan to add a 100,000-ton-per-year high-tech industrialization project, which would raise total production scale to 300,000 tons and increase projected annual sales revenue to 180 million yuan.
Business Operations and Segments
The company operates as an integrated supplier of calcium carbonate-based industrial materials. Its business model combines:
- Research and development
- Production
- Marketing
- Customer service
Its core product lines are organized around two main material families:
- Calcium carbonate products, which are used broadly in industrial formulations, including plastics and coatings.
- Calcium hydroxide and calcium oxide products, marketed under the “Shiyuan” brand, with a stronger orientation toward environmental treatment and regulated-use sectors.
The company also states that it can provide customized products according to customer requirements, which is typical of specialist filler and mineral materials suppliers serving multiple downstream industries.
Products and Technologies
Bushi New Material’s principal products are light calcium carbonate and related calcium-based materials. In plastics, calcium carbonate is commonly used as a cost-reducing and performance-modifying filler, helping adjust stiffness, whiteness, processing behavior, and surface characteristics in polymer compounds. The company’s product range is therefore relevant to plastics compounding even though it is not a plastics processor itself.
Key technical features described by the company include:
- Domestic advanced production equipment for calcium carbonate manufacturing.
- A complete set of testing instruments for calcium carbonate quality control.
- Emphasis on stable product quality and superior performance through academic and expert guidance.
- A low-lead calcium hydroxide line intended for more demanding applications where impurity control matters.
The company also states that its products are environmentally friendly and meet SGS-standard requirements. In practical industry terms, this suggests attention to purity, consistency, and compliance-sensitive end uses, particularly for customers with technical specifications for plastics, coatings, and environmental treatment materials.
Applications and End Markets
Bushi New Material serves several industrial markets, with plastics as one of the principal downstream sectors. Reported application areas include:
- Plastics
- Rubber
- Papermaking
- Coatings
- Building materials
Its calcium hydroxide and calcium oxide products are described as suitable for:
- Pharmaceutical and food-related industries
- Sewage treatment
- Acid-neutralization treatment
- Flue-gas desulfurization
- Waste incineration
- Coatings
- Building materials
- Leather making
This broad customer base reflects the role of calcium-based minerals as cross-industry industrial inputs, especially where low cost, mineral reinforcement, pH control, or chemical reactivity is required.
Global Presence and Market Position
Publicly available company information describes Bushi New Material as a domestic Chinese supplier centered in Zhejiang Province, with no clear evidence in the provided sources of overseas manufacturing bases or a large international operating footprint. Its market presence appears to be concentrated in the Chinese industrial materials market, where it supplies customers in multiple downstream sectors.
ChinaPlas exhibitor information lists the company on its eMarketplace platform and identifies it with the designation “Shining Niche”, suggesting a specialized position rather than a large diversified materials conglomerate. Based on the available material, Bushi New Material appears to occupy the role of a regional specialist producer with a focus on mineral fillers and calcium-based functional materials.
Sustainability and Environmental Initiatives
The company presents its products as environmentally friendly and states that they comply with SGS standards. It also highlights uses of its calcium hydroxide and calcium oxide products in wastewater treatment, acid neutralization, and flue-gas desulfurization, which are core industrial environmental-treatment applications.
From an industry perspective, these uses place the company within the broader trend of mineral-material suppliers supporting pollution control and process-neutralization functions. At the same time, the company’s core calcium carbonate products are tied to conventional bulk-material markets, including plastics, where sustainability performance depends more on the customer’s compound design and end-of-life context than on the filler alone.
Financial Performance and Economic Impact
The company states that it has an annual output value of approximately 120 million yuan, annual output of about 200,000 tons, and profits and taxes of more than 5 million yuan. It has also projected that an expansion program could lift annual sales revenue to 180 million yuan.
Economically, Bushi New Material contributes to the local industrial economy through employment, industrial output, and the development of upstream mineral processing capacity in Zhejiang Province. Its operations also support downstream manufacturing sectors that depend on low-cost, high-volume inorganic additives, especially plastics and coatings.
Leadership and Corporate Governance
The available sources do not provide a detailed public management roster or board structure. Company materials do state that Bushi New Material adheres to a business philosophy of “integrity, win-win results, and creating the future together” and uses a “humanized and dynamic” management model.
In governance terms, the most concrete public indicators available are its reported ISO 9001:2000 management system certification, product testing infrastructure, and quality-control practices across raw materials and production processes.
Innovations and Future Outlook
Bushi New Material’s innovation profile is centered on process quality, product customization, and capacity expansion rather than on highly specialized polymer chemistry or downstream plastics conversion. Its collaboration with domestic universities and experts, as described by the company, indicates a continuing emphasis on technical support and product refinement.
Future development will likely depend on several factors:
- Demand growth in plastic filler and industrial mineral markets
- Competition from other calcium carbonate suppliers
- The ability to maintain consistent purity and particle-performance characteristics
- Execution of planned capacity expansion
- Compliance with increasingly stringent environmental and quality standards
If the company completes its stated expansion project, it would strengthen its scale position in mineral materials supply while reinforcing its role as a specialist provider to plastics and other industrial sectors.
Summary
Zhejiang Bushi New Material Co., Ltd. is a specialized calcium carbonate and calcium-based materials producer serving plastics, rubber, coatings, papermaking, building materials, and environmental-treatment markets. Its significance in the plastics industry lies in its role as a functional filler supplier rather than a plastics converter, with product quality, customization, and production capacity forming the core of its competitive identity.
