In the intricate world of rubber manufacturing, the selection of the right vulcanization accelerator is paramount to achieving desired product properties and efficient production cycles. Among the array of available accelerators, N,N'-Diethylthiourea, commonly known as DETU (CAS 105-55-5), stands out for its specific advantages, particularly in specialized rubber applications. As a leading chemical manufacturer and supplier, we understand the critical role DETU plays, and this article delves into why discerning rubber compounders opt for this high-performance additive.

Understanding DETU's Chemical Profile

Diethylthiourea (C5H12N2S) is a thiourea derivative characterized by its white crystalline powder appearance. With a molecular weight of 132.23 and CAS number 105-55-5, it is recognized for its efficacy as an ultra-accelerator. Its chemical structure allows it to actively participate in the vulcanization process, promoting faster curing times, which is a significant advantage for manufacturers aiming to increase throughput.

Key Applications and Performance Benefits

DETU is primarily utilized in the vulcanization of specific elastomers, including Chloroprene rubber (CR), Ethylene Propylene Diene Monomer (EPDM) rubber, and Chlorobutyl rubber. In CR, it contributes to excellent tensile strength, hardness, and reduced compression set. Its ability to function as a vulcanization activator when used with sulfur donors, such as thiuram sulfides, further enhances its versatility. For CR and other diene rubbers, while sometimes considered for special cases, DETU offers faster scorching and curing compared to some alternatives like NA-22, yet it provides better vulcanization flatness. This balance is crucial for maintaining processability and product consistency.

Furthermore, DETU serves as an effective accelerator for butyl rubber and a critical vulcanization activator for EPDM. Its antioxidant properties are also a notable benefit, providing protection for natural rubber, chloroprene rubber, nitrile rubber, and styrene-butadiene rubber, thereby extending the service life of the final products. This dual functionality makes it a cost-effective choice for many formulators.
