The rubber accelerator OTOS is characterized by several distinctive features:
Efficiency and Delayed Action: As a primary accelerator for rubbers such as natural rubber, styrene-butadiene rubber (SBR), ethylene-propylene-diene monomer (EPDM), and other general-purpose rubbers, OTOS demonstrates high efficiency in vulcanization processes. Its notable delayed action prevents premature vulcanization (scorching), providing a broader safe processing window.
Superior High-Temperature Performance: With a vulcanization threshold temperature of 149°C, OTOS is particularly effective in high-temperature vulcanization of natural rubber, imparting excellent reversion resistance and heightened thermal stability to the finished products.
Enhanced Physical and Mechanical Properties: Use of OTOS leads to increased tensile strength, reduced permanent set, lower compression set heat generation, and improved elasticity in vulcanizates, all of which significantly contribute to the overall physical performance of rubber goods.
Synergistic Effects: When combined with other accelerators like benzothiazoles or sulfenamides, OTOS exhibits synergies that optimize vulcanization conditions and may allow for a reduction in total accelerator dosage, benefiting both cost-effectiveness and formulation flexibility.
Processing Safety: Compared to accelerators like MBT and MDB, OTOS offers improved safety during processing, mitigating risks associated with mixing and handling in the manufacturing process.
Environmental Friendliness: Certain formulations of OTOS, such as OTOS-80 pre-dispersed masterbatch, emphasize environmental compatibility, aligning with the contemporary emphasis on green and sustainable materials in the rubber industry.
In summary, OTOS rubber accelerator, with its unique balance of properties, plays a pivotal role in rubber product manufacturing, especially in applications requiring stringent control over vulcanization characteristics, heat resistance, and processing safety.
