Introduction
SHANXI YUZHU ACTIVATED CARBON MANUFACTURING CO., LTD. is a Chinese specialized materials company focused on calcium-based new materials and functional additives for the plastics industry, including plastic deodorant agents, deodorant masterbatches, and matting agents. The company is based in Shanxi and is associated with the Yuzhu Group, which operates from a calcium-based new materials industrial park in Shanyin County and has expanded through branches in Beijing, Shenzhen, and Taiyuan.
In addition to its plastics-oriented functional products, the company operates industrial production capacity for refined calcium oxide, high-surface-area calcium hydroxide, and alkaline precipitated silica, reflecting a broader materials platform built around calcium chemistry and powder processing. Public industry listings also describe the company as developing microporous calcium silicate powder and related application technologies, indicating an emphasis on functional filler and additive systems rather than commodity plastics alone.
The company has been recognized in Chinese innovation-oriented enterprise programmes, including high-tech enterprise and specialized and niche SME listings, which place it within China’s policy-supported segment of technology-focused industrial suppliers.
History and Development
The company’s development is closely tied to the build-out of the Shanyin calcium-based new materials industrial park, which serves as the manufacturing base for the Yuzhu group’s calcium chemistry businesses.
Key milestones in its public record include:
- 2018: The company appeared in Shanxi’s list of proposed technology-based SMEs, indicating an early formal recognition of its technology orientation.
- 2021: It was included in Shanxi’s filing list for high-tech enterprises, under the designation GR202114000998.
- 2024–2025: The company again appeared in high-tech enterprise and specialized and niche SME recognition lists, including a 2025 provincial re-verification notice.
Patent records also show activity in powder preparation and microporous calcium silicate processing, suggesting continuing process development beyond standard bulk-material production.
Business Operations and Segments
The company’s business model combines inorganic material manufacturing with functional additive development for downstream polymer and coating applications.
Its main activity areas include:
- Calcium-based new materials
- Functional plastic additives
- Powder materials and mineral processing
- Application development and market sales
Public listings indicate that the company has established production lines for:
- 25万吨/年 refined calcium oxide
- 5万吨/年 high-surface-area calcium hydroxide
- 1万吨/年 alkaline precipitated silica
It also reports production lines for plastic deodorant agents, deodorant masterbatches, and matting agents, which connect its inorganic material base to polymer compounding and appearance/function enhancement.
Products and Technologies
The company’s product portfolio combines mineral-based intermediate materials with plastic functional masterbatches and additives.
Core material products
- Refined calcium oxide
- High-surface-area calcium hydroxide
- Alkaline precipitated silica
- Microporous calcium silicate powder
Plastics-related functional products
- Plastic deodorant agents
- Deodorant masterbatches
- Matting agents
Technical characteristics
The available descriptions suggest several technical priorities:
- Odour control for plastics processing and finished goods
- Surface modification / matting for appearance adjustment
- Powder engineering and microporous structures for adsorption-related performance
- Calcium-based formulation systems that can be integrated into compounded plastics or adjacent industrial materials
The company’s patent footprint includes a method for preparing microporous calcium silicate powder and a crushing and screening machine plus powder preparation process, indicating process-side capability in particle-size control and powder functionality.
Applications and End Markets
The company’s product descriptions point to use in plastic compounding, packaging, and other functional-material applications.
Reported application areas include:
- Food packaging
- Medical packaging
- Plastic pipe
- Household plastic products
- Photovoltaic backsheet film
- Optical applications
Broader listings also indicate end-use relevance in:
- Daily chemical products
- Personal care packaging
- Wire and cable
- Automotive parts
- Agricultural applications
These applications suggest that the company serves downstream sectors where odor reduction, appearance control, and material consistency are commercially important.
Global Presence and Market Position
The company states that its products are sold throughout China and exported to regions including Asia, Germany, Argentina, Australia, Senegal, and Canada, indicating an international customer base for its masterbatch and functional additive products.
Within China’s plastics-materials ecosystem, the company appears as a specialized supplier rather than a broad polymer producer. Its positioning is strengthened by inclusion in CHINAPLAS recommended exhibitor lists for specialized and niche Chinese enterprises, which places it among suppliers marketed around advanced functionality and application-specific materials.
Research and Development
Research and development is a visible element of the company’s identity. Industry listings describe a team focused on plastic colouring, modification, and functional additive development, supported by a 1,000-square-metre laboratory.
R&D themes include:
- Environmental and low-carbon formulations
- Deodorizing masterbatch systems
- Matting and appearance-control additives
- Microporous calcium silicate powder synthesis
- Powder processing equipment and preparation methods
The company’s recurring recognition as a high-tech enterprise and a specialized and niche SME further supports its positioning as a process- and formulation-driven manufacturer.
Sustainability and Environmental Initiatives
The company’s public materials explicitly connect its additive development to green and low-carbon development.
Its relevant sustainability-oriented themes include:
- Odour reduction in plastics, which can support lower-emission processing or improved indoor use performance
- Functional masterbatches that reduce the need for separate processing steps
- Mineral-based formulations associated with inorganic filler and adsorbent chemistry
- Environmental product development described as part of its newer production lines
These activities align with broader plastics-industry trends toward functionalization, processing efficiency, and reduced environmental impact in downstream applications.
Quality Management and Certifications
Public enterprise records identify the company as a high-tech enterprise in Shanxi, with later re-confirmation in provincial listings.
In CHINAPLAS-related materials, the company states that it follows scientific management and standardized production and inspection processes, and that product quality is stable. It also reports participation in specialized industry organizations, including membership in a committee under the China Plastics Processing Industry Association.
Innovations and Future Outlook
The company’s future development appears tied to three intersecting trends in the plastics industry:
- Functional masterbatches for higher-value performance plastics
- Low-odor and low-carbon material solutions
- Calcium-based powder engineering for broader downstream formulation uses
Its industrial base in calcium chemistry gives it flexibility to serve not only plastics compounding but also adjacent sectors that require adsorptive powders, surface-modifying additives, and mineral functional materials.
The company’s continuation in government-backed innovation categories suggests a business profile oriented toward process improvement, application development, and specialty material integration rather than volume-only commodity production.
