N,N-Dicyclohexylbenzothiazole-2-sulphenamide (CAS 4979-32-2) Market Summary

The N,N-Dicyclohexylbenzothiazole-2-sulphenamide (DCBS, CAS #4979-32-2) market represents a specialized niche within the rubber chemicals and vulcanization additives industry, where this delayed-action sulfenamide accelerator—known for its exceptional scorch resistance and processing safety—plays a critical role in optimizing the curing process for natural and synthetic rubber compounds, particularly those reinforced with fine-particle furnace blacks, enabling the production of high-strength, durable products like radial tires, conveyor belts, and OTR tires that withstand extreme dynamic stresses without premature gelling or reversion. This light beige to off-white powder, characterized by its molecular formula C19H26N2S2 and melting point of 96–100°C, functions as a semi-ultra accelerator that decomposes under thermal activation (140–160°C) to release mercaptobenzothiazole (MBT) intermediates, facilitating controlled polysulfide cross-linking with flat rheometer curves (ΔM >10 dNm) and extended scorch times (tS2 >10 minutes at 121°C per ASTM D5282), while its cyclohexyl substituents confer low volatility (vapor pressure <0.01 mmHg at 25°C) and excellent dispersibility (<5 μm aggregates via SEM) in NR/BR/SBR blends, recirculating via masterbatch for 98% homogeneity without dust hazards in extrusion dies. As a thiazole derivative, its affordability—derived from economical aniline and cyclohexylamine synthesis—and ease of production via oxidative coupling position it for widespread use at 0.6–1.5 phr loadings, often in combination with thiurams for 20–30% faster cure rates in low-sulfur (0.5–1.0 phr) systems, compliant with REACH Annex II for non-hazardous classification and RoHS for cable sheathing. This market's momentum is inextricably linked to the radial tire revolution—global output surpassing 2.4 billion units annually—and the surge in industrial belting, where DCBS's superior latency mitigates 25% processing risks in thick cross-sections (>50 mm) for steel cord conveyor belts. As sustainability pressures intensify—mandating 20% bio-based additives by 2030 under EU's Circular Economy Action Plan—DCBS evolves from standard sulfenamide to low-dose hybrids with nano-clays for 30% reduced volatility, curbing 1.2 t CO₂/ton emissions via greener aniline routes. The global N,N-Dicyclohexylbenzothiazole-2-sulphenamide market is estimated to reach a valuation of approximately USD 106–171 million in 2025, with compound annual growth rates projected in the range of 5%–7.5% through 2030. This trajectory reflects the rubber accelerators segment's maturation, bolstered by tire radialization (95% market share) and the expansion of rubber-metal composites in mining hoses and retreading, alongside regulatory tailwinds favoring low-scorch agents under TSCA and GB/T 12625, cultivating a resilient ecosystem that harmonizes cure efficiency with environmental compliance in an era of circular tire economies and supply chain diversification.

Application Analysis and Market Segmentation
● Natural Rubber Applications
Natural Rubber (NR) compounds harness N,N-Dicyclohexylbenzothiazole-2-sulphenamide as a delayed-action accelerator for superior scorch safety in latex dipping and extrusion, where its sulfenamide moiety decomposes to MBT mercaptide at 140–150°C for plateaued rheocurves with maximum torque ΔM >12 dNm per ASTM D5282, enabling 98% crosslink density in skim stocks for tire plies without reversion in open steam (121°C/30 min) while its dicyclohexyl groups avoid tackiness (<3 N/cm in roll-build per ISO 2230) or blooming in warehouse storage (6 months at 30°C/60% RH). Dosed at 0.8–1.2 phr with 1.5 phr sulfur, it recirculates via prevulcanization inhibitors (PVI) for 25% storage stability in NR latex, essential for processing 5–10 million tons annual global crepe yields.

At 0.7–1.1 phr with 0.8 phr sulfur, it synergizes with thiurams for 25% faster rheocure in cable sheathing, compliant with UL 44 for 90°C wet ratings. Growth is projected at 4.5%–6.5% annually, underpinned by SR's 4% CAGR to 15 million tons by 2030 and the need for scorch-resistant grades in automotive weatherstrips, compliant with EN 60811 aging. Innovatory arcs spotlight DCBS-MBT hybrids, as in BASF's Buna CB rubber where 0.9 phr boosts 35% ozone resistance in glazing seals, harmonizing with REACH Annex XVII for low-volatiles in food-contact EPDM.

Growth Trends in the N,N-Dicyclohexylbenzothiazole-2-sulphenamide Market
The trajectory of the N,N-Dicyclohexylbenzothiazole-2-sulphenamide market is illuminated by its chemical versatility and expanding industrial utility, chronologically delineating a progression from core synthesis to specialized applications. Commencing with structural hallmarks, this compound is recognized as a delayed-action sulfenamide accelerator with excellent dispersion in rubber, long scorch time, high processing safety, and applications in high-activity fine-particle furnace black compounds, particularly for radial tires, making it superior for dynamic stress handling in products like steel cord belts, OTR tires, and retreading. This profile, rooted in its dicyclohexyl substitution and benzothiazole ring, enables seamless integration into rubber without excessive volatility, a trait that has historically lowered gelling risks by 20–30% in processing workflows since its commercial emergence in the mid-20th century. Building on this, it primarily finds application as a superior accelerator in natural and synthetic rubber, where it can be used alone or combined with other accelerators, offering superior scorch resistance and enabling durable, high-tensile rubber products that resist high temperatures and cracking, suitable for common items like automobile tires and cables, with its use surging alongside tire production and radialization rates, driving increased demand for CBS, TBBS, and DCBS. This dual role, documented in early rubber chemistry texts from the 1960s, propelled initial market adoption in Asia's tire heartlands, with China's 800 million annual units by the 1990s indirectly boosting demand through sulfenamide formulations for sidewall flexing. Furthering its utility, it functions as an intermediate in preparing high-adhesion compounds for steel-reinforced belting and hoses, leveraging oxidation to mercaptobenzothiazole for radical initiation in sulfur cures, achieving network densities >90% under mild alkaline conditions. This intermediary prowess, amplified by 1980s advancements in delayed-action tuning, has sustained 5–7.5% annual growth in polymer intermediates, particularly in U.S. and European pipelines for automotive weatherstripping. Moreover, it is employed in natural rubber for tire carcasses, metal skeleton rubber for industrial hoses, and retreading for fleet renewals, where its sulfenamide structure enables amphiphilic assemblies via RAFT polymerization, yielding composites with 80% interfacial cohesion for off-road treads. This structuring trend, gaining traction post-2000 with sustainability booms, aligns with precision vulcanization, as evidenced by 2020s publications on DCBS hybrids for recycled tire retreading, portending a 10–15% CAGR in advanced materials through 2030.
