Propelling Vulcanization of Rubber with Reduced Sulfur Content Vulcanization of rubber by sulfur alone is a time-consuming process, resulting in poor mechanical properties due to oxidative degradation of rubber. As a result, vulcanization accelerators are increasingly being adopted in the rubber industry to boost the process with minimal rubber degradation. Vulcanization accelerators, such as thiazoles, create sulfur bridges between individual polymer molecules while being heated with rubber. In addition, vulcanization accelerators behave as sulfur donors, allowing vulcanization to progress at lesser sulfur content. Thiozoles hasten the cross-bonding reaction between sulfur and rubber occurring at the carbon-carbon double bonds (C=C) in excessive amounts of sulfur. As such, thiozoles reduce the amount of sulfur required to cross-link polymers, improving the durability of the vulcanized rubber. Thiozoles, combined with trace quantities of basic accelerators - diphenyl guanidine (DPG), and diorthotolyl guanidine (DOTG), enhances cure speed, scorch delay, and crosslink density. As such, the tensile and resilience properties of the cured rubber are improved. Addition of activators, including zinc oxide, or stearic acid, adorns the efficacy of sulfur-based cure systems, and produce flat cure with better reversion resistance. Furthermore, vulcanization accelerators, such as sulfonamides, are fast curatives and result in a delay in the onset of vulcanization – ideal for rubber processing following increased scorch time.

Sulfenamide and Dithiocarbamate Vulcanization Accelerators - Complementing the Mechanical Properties of Vulcanized Rubber Sulfenamide class accelerators are commonplace in the tire industry in light of delayed action, as well as faster cure rate during vulcanization of rubber compounds containing furnace blacks. Subsequent increase in amount of sulfenamide accelerators improves in scorch delay, cure rate, and state of cure. Further inclusion of basic accelerators, including DPG, DOTG, TMTM, TMTD, increases the cure rate, yet the scorch safety is slightly compromised. Sulfenamide vulcanization accelerators showcase greater stress-strain aspects in tandem with better resilience and flex-fatigue resistance against thiozoles. Sulfenamide accelerators disintegrate swiftly in the presence of steam, making them suitable for manufacturing open steam cured rubber products which require faster onset of cure for enhanced shape retention. Blooming of rubber compounds leads to poor linking to the following process, decreasing the appearance quality of the final offering. Large alkyl vulcanization accelerators – ZDEC, and ZDBC – exhibit high compatibility with rubber, thereby reducing the blooming phenomenon. Vulcanization accelerators, including ZMBT, TMTD, and MBT, are highly suitable for the production of latex products owing to good water solubility aspect.

Surging Automobile Production in East Asia Grabs Market Players Attention Upswing in passenger vehicle production in East Asia remains the goldmine of growth for the market of vulcanization accelerators, with China, Japan, and South Korea representing the progress. With environmental amendments standing akimbo, countries, including Japan, and China are mandating labeling of tires in a bid to curb environmental degradation. In addition, regulatory bodies are offering incentives to manufacturers and customers turning to high performance silica reinforced tires. The industrial sector in China is witnessing an uplift to satiate the demand for equipment parts - rubber conveyor belts, rubber hoses, rubber-lined strainers, rubber-lined dish ends, and rubber-lined bends. As such, market players are eyeing East Asia for expanding production footprint.

Stakeholders Innovate Existing Products to Gain Competitive Advantage Binary accelerator - MBTS/TMTD - offers myriad of benefits - low scorch time, high cure rate, low reduction of mechanical properties, optimum aging resistance, and compatibility blend, motivating manufacturers to focus on the development of binary vulcanization accelerators. Secondary vulcanization accelerators pose the risk of releasing carcinogens due to the decomposition of the amine compound. Manufacturers are increasing the production of primary vulcanization accelerators. Furthermore, rising cardiac disorders, pediatrics, as well as critical life-saving methods is propelling the demand for medical grade rubber equipment. As such, market players are tapping white spaces in the medical sector.

How Growth Will Unfold Realizing environmental concerns, governments in the US and the European Union are imposing regulations that mandate tire labeling from A to E based on three parameters - wet grip, noise, and rolling resistance. Increasing demand for high performance tires following higher fuel efficacy, and minimal increase in production costs is set to drive the market for vulcanization accelerators. In addition, vulcanization Accelerators offer enhanced rolling resistance, as well as improved wet and dry traction. Automobile manufacturers are inflating vehicle fleet size citing the amplifying trend of ‘private vehicle ownership’, resulting in increased demand for aftermarket car maintenance and services. As such, the adoption of vulcanization accelerators will mushroom in the automotive space where a single automobile unit is installed with rubber-based ancillary parts and tires. On the flip side, countries, including India, and the European region are imposing anti-dumping duties on imported tires due to ecological depletion. The US-China trade conflict is further complementing the challenging situation – a restraining factor for the growth of the vulcanization accelerators market.
