In the specialized world of rubber compounding, the choice of accelerators plays a pivotal role in dictating both processing efficiency and the final properties of the elastomer. Ethylene Thiourea (ETU), a highly effective chemical auxiliary agent, is particularly significant for its contributions to EPDM and CR rubber formulations. Understanding the nuanced benefits of ETU is crucial for rubber chemists and manufacturers aiming to optimize their products. We, as a dedicated supplier, provide insight into its advantages.

ETU, known by its CAS number 96-45-7, serves as a key accelerator for polychloroprene (CR) rubber. It functions as a primary accelerator or a secondary ultra-accelerator, contributing to fast vulcanization rates while offering good scorch safety. This means that CR compounds can be processed more efficiently without premature curing, a critical factor for maintaining product quality and manufacturing throughput. Furthermore, ETU enhances the physical properties of CR vulcanizates, leading to improved tensile strength and a lower compression set.

For EPDM (Ethylene Propylene Diene Monomer) rubber, ETU acts as a potent booster. While EPDM often utilizes different accelerator systems, ETU can be incorporated to further enhance cure speed and impart specific desirable properties. Its ability to improve heat resistance and aging performance makes it valuable for EPDM applications that require longevity and reliability in challenging environments. This makes it a sought-after chemical for manufacturers in automotive and industrial sectors.
