Tetramethylthiuram Disulfide

Rubber Accelerator TMTD Market Intelligence Report

I. Recent Price Dynamics
- Latest Quotation: As of May 9, 2026, the latest quotation for rubber vulcanization accelerator TMTD (99% purity) is RMB 11,800 per ton, offered by Jiangsu Xinshu New Materials Co., Ltd., with delivery at Suzhou City, Jiangsu Province.
- Historical Price Trend: TMTD prices have remained relatively stable recently, with no significant fluctuations. According to publicly available information, short-term TMTD pricing has not been materially affected by notable supply-demand shifts or policy adjustments.

II. Market Supply-Demand Analysis
- Supply Side:
- Capacity and Utilization Rate: In 2025, China’s total TMTD production capacity reached 92,000 tons/year, with an average operating rate maintained at approximately 73%, indicating suboptimal capacity utilization.
- Production Concentration: The TMTD industry exhibits high production concentration; the top five enterprises collectively account for over 65% of national capacity, with Shandong Yanggu Huatai Chemical Co., Ltd. holding the largest share at 22%. While this concentrated industrial structure facilitates unified technical standards and effective environmental regulation enforcement, it also constrains regional supply elasticity.
- Demand Side:
- Consumption Volume: China’s apparent consumption of TMTD in 2025 totaled approximately 68,000 tons—representing a 12.3% increase from 2020, with a compound annual growth rate (CAGR) of 2.3%.
- Application Segments: As a highly efficient sulfur-donor-type accelerator, TMTD is widely used in the vulcanization of natural rubber, styrene-butadiene rubber (SBR), and polybutadiene rubber (BR), particularly in tire tread compounds, industrial rubber hoses, and compression-molded products—where its functional role remains irreplaceable. In 2025, the tire manufacturing sector consumed ~41,000 tons of TMTD, accounting for 60.3% of total consumption.

III. Industry Pain Points and Challenges
- Structural Imbalance: A dual contradiction persists in the TMTD market—underutilized overall capacity coexists with insufficient supply of high-end products. Annual production capacity for high-purity TMTD (≥99.0%) remains below 8,000 tons, failing to meet stringent international requirements regarding purity, heavy metal residue levels, and secondary amine content.
- Environmental Compliance Pressure: Escalating environmental regulations have significantly increased compliance costs. In 2025, average environmental expenditure accounted for 9.6% of industry revenue; hazardous waste disposal unit costs surged 132% over the past five years. Small- and medium-sized enterprises (SMEs) face an average environmental cost of RMB 2,800 per ton of product—trapped in a ‘non-compliance means shutdown, compliance means losses’ dilemma.
- International Regulatory Risks: The EU REACH regulation added TMTD to its Candidate List of Substances of Very High Concern (SVHC) in 2024. Coupled with regulatory pressures under U.S. TSCA and Japan’s Chemical Substances Control Law (CSCL), export order compliance thresholds have risen substantially.
- Green Substitution Trend: Accelerating adoption of eco-friendly vulcanization accelerators is eroding traditional market share. Globally, low-nitrosamine accelerators—including TBBS and ZBEC—now account for 31.4% of total accelerator consumption. Within China’s tire sector, TMTD’s usage share declined from 65.2% in 2020 to 60.3% in 2025, and is projected to register negative growth for the first time in 2026.

IV. Analysis and Outlook
- Short-Term Price Trend: Given balanced supply-demand fundamentals and absence of major near-term supply-demand shocks or policy interventions, TMTD prices are expected to remain relatively stable in the short term.
- Long-Term Market Trends:
- Capacity Optimization and Green Transformation: Intensifying environmental regulation and accelerating green substitution will subject the TMTD industry to dual pressures—capacity optimization and green transformation. Over the next five years, the industry is expected to advance green process upgrades and capacity rationalization in phased steps, enhancing high-end supply capabilities to meet international clients’ rigorous demands on product quality and environmental performance.
- Technological Innovation and Process Upgrading: Lab-scale achievements using low-toxicity, high-efficiency synthesis technologies—including microchannel continuous-flow reactors and ionic liquid catalysis—have achieved yields up to 96.7%. However, scale-up entails high engineering risks and prolonged investment payback periods. Going forward, sustained technological innovation and progressive process upgrading are expected to reduce production costs while simultaneously improving product quality and environmental performance.
- Evolving Competitive Landscape: Significant gaps persist between domestic leading enterprises and global industry leaders in areas such as continuous production capability, green certifications, and full-lifecycle cost management. SMEs may achieve differentiated breakthroughs by focusing on niche applications—including reclaim rubber activation and specialty rubber hose formulations. Meanwhile, collaborative mechanisms—including industry alliances and jointly developed standard systems—will be critical to elevating the sector’s overall competitiveness.
