# Market Dynamics Intelligence, Analysis, and Forecast for the Rubber Accelerator MBTS Market

## I. Market Dynamics Intelligence

1. Market Size and Growth
- **2025 Market Size**: The Chinese market size for rubber accelerator MBTS reached RMB 3.86 billion in 2025, representing a year-on-year increase of 6.2%.
- **2026 Market Size Forecast**: The Chinese market size is projected to reach RMB 4.10 billion in 2026, marking a 6.2% growth compared to 2025, with a stable growth rate.

2. Capacity and Production
- **Capacity Distribution**: Major domestic producers include Shandong Shangshun Chemical Co., Ltd., Nanjing Jintong Chemical Co., Ltd., and Hebei Kaiwei Chemical Co., Ltd. Among them, Shandong Shangshun Chemical has an annual MBTS production capacity of 52,000 tons in 2025, accounting for approximately 28.3% of the national total capacity, making it the largest single production base in China.
- **Production Volume**: The total national production of MBTS in 2025 was 93,000 tons, a 6.9% increase from 87,000 tons in 2024. The capacity utilization rate reached 84.5%, the highest level in the past five years.

3. Import and Export Situation
- **Export Volume**: China's MBTS export volume reached 127,000 tons in 2025, a year-on-year increase of 9.1%, primarily flowing to emerging tire production bases in Southeast Asia, the Middle East, and South America.
- **Export Growth Forecast**: Under the RCEP framework, deepened tariff reductions and the establishment of localized technical service teams are expected to stabilize export growth in the 7.5%–8.0% range in 2026.

4. Price Dynamics
- **2025 Price**: The mainstream ex-factory average price of MBTS in China was RMB 41,500 per ton in 2025, a slight increase of 1.2% compared to 2024. This increase was significantly lower than the average 7.3% rise in upstream raw materials such as aniline and carbon disulfide.
- **Price Trend**: Bargaining power within the industry chain is moderately shifting back to midstream additive manufacturers. Prices are expected to remain stable or increase slightly in 2026.

5. Policy and Environmental Protection
- **Policy Support**: The National \"14th Five-Year Plan for the Raw Materials Industry\" lists high-performance rubber additives as a key area for technological breakthroughs, providing equipment investment subsidies for clean production processes of sulfur-containing accelerators.
- **Environmental Regulation**: The Ministry of Ecology and Environment requires full coverage of online monitoring for VOCs emissions by all rubber additive production enterprises before 2026, forcing small and medium-sized enterprises (SMEs) to exit or be integrated.

## II. Analysis and Judgment

1. Continuous Growth in Market Demand
- **Downstream Applications**: MBTS is widely used in high-performance rubber products such as tires, hoses, belts, and seals. With the steady recovery of domestic automotive production and sales, the rising penetration rate of new energy vehicles, and growing demand for durable rubber components in high-end equipment manufacturing sectors like rail transit and engineering machinery, the application space for MBTS continues to expand.
- **Tire Industry**: The tire industry is accelerating its transition to green and low-carbon production. The synergistic use ratio of MBTS and TBBS in all-steel radial tires is increasing, while the irreplaceability of MBTS in low-cost formulations for passenger car tires is further strengthening, driving MBTS demand growth.

2. Increasing Capacity Concentration
- **Advantages of Leading Enterprises**: Leading enterprises have released high-purity MBTS capacity through technical upgrades, effectively supporting the strict requirements of high-end customers for batch stability and low heavy metal residue, thereby pushing average prices upward.
- **Exit of SMEs**: Stricter environmental regulations are accelerating the exit or integration of SMEs. Market concentration is rising, with the top five enterprises (CR5) holding a combined market share of 68.3%, an increase of 4.1 percentage points compared to 2024.

3. Significant Potential in Export Markets
- **Emerging Markets**: China's MBTS exports primarily flow to emerging tire production bases in Southeast Asia, the Middle East, and South America. With deepened tariff reductions under the RCEP framework and the construction of localized technical service teams, export market potential is further releasing.
- **International Competitiveness**: Domestic enterprises are gradually enhancing their bargaining power in international mid-to-high-end supply chains, with export average prices being higher than domestic sales prices by a certain margin.

## III. Forecast

1. Market Size Forecast
- **Short-term Forecast**: The Chinese MBTS market size is expected to reach RMB 4.10 billion in 2026, representing a 6.2% year-on-year growth, with a stable growth rate.
- **Long-term Forecast**: Over the next three years, the field will continue to maintain an annual compound growth rate of 5%–6%. However, the focus of investment returns has shifted from scale expansion to process refinement, customer structure optimization, and the construction of green certification capabilities.

2. Price Trend Forecast
- **Price Stability**: As bargaining power within the industry chain moderately shifts back to midstream additive manufacturers, and as leading enterprises release capacity and improve cost control capabilities, MBTS prices are expected to remain stable or increase slightly.
- **Premium for High-End Products**: The proportion of high-end MBTS products, such as high-purity and surface-modified varieties, will increase, driving up the average price.

3. Competitive Landscape Forecast
- **Leadership by Leading Enterprises**: Leading enterprises with scaled, refined operational capabilities and environmental compliance qualifications will continue to dominate the market, further increasing their market share.
- **Transformation of SMEs**: SMEs will face greater challenges; some will transform through technological upgrades and differentiated competition, while others will exit the market.

4. Export Market Forecast
- **Growth in Export Volume**: With deepened tariff reductions under the RCEP framework and the construction of localized technical service teams, China's MBTS export volume will continue to grow.
- **Optimization of Export Structure**: Export products will develop towards high-end and customized directions, enhancing competitiveness in the international market.
