TIANSHENG PLASTIC ADDITIVES CO., LTD.

परिचय

TIANSHENG PLASTIC ADDITIVES CO., LTD. (Chinese: 九江天盛塑料助剂有限公司) is a Chinese manufacturer of PVC heat stabilizers and related plastic additives based in Hukou County, Jiujiang, Jiangxi Province. The company’s reported product mix centers on calcium-zinc composite stabilizers, compound stabilizers, tribasic lead sulphate, dibasic lead phosphite, metal stearates, and ACR processing aids, positioning it within the specialized segment of the plastics industry that formulates additives used to control heat stability, processing behavior, and end-use performance in PVC and related polymers.

The company reports that it was established in 2009, operates from Jinshawan Industrial Park in Hukou County, and has built production capacity for more than 40,000 tons per year of plastic additives. Its business profile indicates a workforce of more than 100 employees, including more than 30 engineers and technicians, and it states that the company maintains multiple production lines and exports to markets in Europe, Asia, and Africa.

Tiansheng is associated with the Yandang Mountain brand and has been described in industry listings as participating in the drafting of standards for tribasic lead sulphate and dibasic lead phosphite. Its product portfolio reflects the broader industry transition from traditional lead-based stabilizers toward environmentally oriented calcium-zinc systems, especially for PVC pipes, profiles, cable materials, films, and foam or board applications.

History and Development

• The company states that it was founded in 2009 and located in Hukou County, Jiujiang, in a logistics corridor connecting the Poyang Lake and Yangtze River regions.
• It reports that the business grew from an earlier plastics additives base and later expanded into a broader range of stabilizers and processing aids under the Yandang Mountain brand.
• Publicly available materials indicate that the company has been recognized in provincial and national high-tech enterprise lists in Jiangxi, including entries for 2017, 2020, and 2023.
• The company also appears in industry exhibition and supplier listings, including a ChinaPlas exhibitor entry and other plastics market directories, reflecting its continued participation in the plastics additives supply chain.

Business Operations and Segments

Tiansheng’s core business is the research, production, and sale of PVC heat stabilizers and companion additive products. Its operations are organized around the formulation and supply of additives used by PVC converters in extrusion, calendering, and related processing routes.

The company’s reported product families include:

• Calcium-zinc composite stabilizers for environmentally oriented PVC formulations.
• Compound stabilizers for a range of rigid and semi-rigid PVC processing uses.
• ACR processing aids, which are commonly used to improve melt strength, fusion behavior, and surface quality in PVC processing.
• Metal stearates and other lubricating or auxiliary additives used in compound formulation.

According to product descriptions, the company serves applications such as PVC pipes, profiles, cable sheathing, calendered film, foam board, and hard PVC extrusions.

Products and Technologies

Tiansheng’s technical profile is centered on stabilizer chemistry for PVC, a segment where formulations must balance thermal stability, lubrication, weatherability, processing window, and compliance requirements.

Key reported products and functional classes include:

• Calcium-zinc stabilizers such as CZ-series products for PVC extrusion and film applications.
• Lead-based stabilizer intermediates including tribasic lead sulphate and dibasic lead phosphite, which remain part of the company’s product catalogue and are associated with traditional stabilizer systems.
• Metal stearates including calcium stearate, zinc stearate, barium stearate, and lead stearate variants, used in lubrication and processing control.
• ACR processing aids such as ACR-201 and ACR-401, which support fusion and rheology control in PVC processing.

The company’s product pages indicate specific end-use grades for:

• PVC calendered film.
• Non-toxic PVC wire and cable insulation and jacketing.
• Rigid PVC foaming, wood-plastic board, and profile extrusion.

From a process perspective, these product classes are technically important because PVC degrades under heat during processing; stabilizers inhibit this degradation, while processing aids and lubricants help maintain flow, dimensional consistency, and finish quality.

Applications and End Markets

Tiansheng’s products are used primarily in PVC processing, especially in sectors that require heat stability and regulated material performance.

Major end markets include:

• Building and construction, including pipes, profiles, boards, and foam products.
• Wire and cable, particularly non-toxic cable sheath and insulation formulations.
• Film and calendering, where stabilizer performance affects clarity, thermal resistance, and production stability.
• Industrial plastics conversion, where compound consistency and processing efficiency are important.

These markets are closely linked to the wider plastics industry’s shift toward formulations with improved environmental profiles, particularly in regions where PVC processors are replacing or reducing older lead-based systems with calcium-zinc alternatives.

Global Presence and Market Position

The company reports sales coverage across China and overseas, with branch or agency presence in cities including Guangzhou, Chengdu, Wenzhou, Beijing, Shanghai, Shandong, Xinjiang, Shanxi, Yunnan, Fujian, Wuhan, Nanchang, Shenyang, Wuxi, and Taizhou. It also states that its products are exported to Europe, Asia, and Africa.

In industry directories, Tiansheng appears as a supplier of plastics additives and was listed as an exhibitor in plastics trade-show related materials, indicating participation in the plastics processing ecosystem beyond its home province.

Research and Development

The company describes itself as engaged in research and development alongside production and sales, and its workforce profile highlights a substantial engineering and technical staff relative to company size. Its public materials also state that certain stabilizer products have received national patents and that the company participates in standards-related work for selected lead stabilizer materials.

Its R&D emphasis appears to be concentrated in:

• PVC formulation improvement.
• Environmental composite stabilizers for lower-toxicity processing systems.
• Process-oriented additive design for extrusion and calendering applications.

Sustainability and Environmental Initiatives

Tiansheng’s sustainability profile is most clearly reflected in its promotion of environmental Ca/Zn composite stabilizers and other formulations marketed for non-toxic PVC applications. These products align with broader regulatory and market pressure across the plastics industry to reduce reliance on lead-based stabilizers in consumer, construction, and wire-and-cable applications.

The company’s product positioning suggests two parallel technical directions:

• continued supply of legacy stabilizer chemistries used in established industrial applications.
• development of environmentally oriented replacement systems for processors seeking safer formulations.

Quality Management and Certifications

Public listings indicate that the company has been recognized as a high-tech enterprise in Jiangxi on multiple occasions and that some of its products carry patent protection. The company also presents itself as a manufacturer with established production lines and quality-oriented product branding under Yandang Mountain.

Innovations and Future Outlook

Tiansheng’s future position in the plastics additives market is likely to depend on the continuing transition in PVC processing toward safer stabilizer systems, tighter process control, and formulation support tailored to specific end uses. Its mix of calcium-zinc systems, ACR processing aids, and compound stabilizers places it in a product category where technical service and application-specific formulation are often as important as commodity supply.

Its reported export activity and broad domestic distribution suggest that the company is positioned as a regional specialist with participation in both the Chinese PVC supply base and selected overseas markets.
