The process of vulcanization is critical for transforming raw rubber into a durable, elastic, and useful material. Rubber vulcanization accelerators are essential for controlling this process, dictating cure rates, and influencing the final properties of the rubber product. Among these, Ethylene Thiourea (ETU), CAS 96-45-7, is a highly valued accelerator, particularly for specific elastomer types. For procurement managers and R&D scientists, understanding ETU and sourcing it from a trusted China manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. is key to ensuring product quality and cost-effectiveness.

The Importance of Vulcanization Accelerators

Vulcanization involves cross-linking polymer chains in rubber, typically using sulfur. Accelerators are chemical compounds that significantly increase the rate of this reaction, allowing vulcanization to occur at lower temperatures and shorter times. This not only improves efficiency but also enhances the physical properties of the rubber, such as tensile strength, abrasion resistance, and resilience. The careful selection of an accelerator is paramount for achieving the desired performance characteristics in applications ranging from tires to industrial seals.

Ethylene Thiourea (ETU): Properties and Applications

Ethylene Thiourea (ETU), with CAS No. 96-45-7, is a white crystalline powder known for its effectiveness as a fast-curing accelerator. It is particularly favored for its:

  • Non-Staining and Non-Discoloring Characteristics: This makes ETU an excellent choice for light-colored or white rubber products where aesthetic appearance is crucial.
  • High Cure Rate: ETU significantly speeds up the vulcanization process, improving production efficiency for manufacturers.
  • Excellent Physical Properties: Rubber vulcanized with ETU typically exhibits high tensile strength, low compression set, and good heat resistance.

ETU is widely used in the vulcanization of chloroprene rubber (CR), chlorosulfonated polyethylene (CSM), and polyacrylate rubber (ACM). For product formulators, the consistent purity and performance of ETU are vital for predictable results.
