N-Cyclohexylthiophthalimide, commonly known as CTP Granular, is a crucial chemical auxiliary agent widely utilized in the rubber industry. With a CAS No. of 17796-82-6 and molecular formula C14H15O2SN, this white granular compound serves as an highly efficient anti-scorching agent. Its primary function is to optimize the vulcanization process, particularly for sulfur vulcanization systems involving natural rubber (NR) and various synthetic rubbers such as SBR, BR, IIR, CR, EPM, EPDM, and NBR. CTP Granular is specifically designed to work seamlessly with sulfonamide and thiazole accelerators, enhancing overall processing efficiency and product quality.
The incorporation of CTP Granular offers a multitude of benefits to rubber manufacturers. Even with a small addition, typically 0.1-0.3 parts, it significantly improves processing safety by preventing premature vulcanization, commonly known as scorch. This critical feature allows for greater flexibility during processing stages, reducing material waste and optimizing production cycles. Furthermore, CTP Granular helps to accelerate specific processing steps, contributing to energy savings and overall cost reduction. Beyond processing, it substantially enhances the storage stability of uncured rubber compounds, preventing natural vulcanization during prolonged storage periods.
A remarkable characteristic of N-Cyclohexylthiophthalimide is its regenerative and restorative effect on rubber materials that have already been subjected to high heat or show signs of scorching. This capability provides a valuable safeguard, allowing for the salvage of potentially compromised batches. The product is meticulously shaped into granular form without the addition of any carriers, a design choice that effectively minimizes dust generation during handling. This granular structure ensures excellent fluidity and dispersibility within rubber mixes, making it particularly suitable for automated weighing systems, a crucial aspect in the production of high-performance products like radial tires.
