In the dynamic world of rubber manufacturing, selecting the right vulcanization accelerator is paramount to achieving desired product properties and efficient processing. N,N'-Diethylthiourea, commonly known as DETU (CAS 105-55-5), stands out as a highly effective thiourea-based accelerator, prized for its rapid vulcanization capabilities and unique performance characteristics. As a dedicated supplier of high-quality chemical additives, we aim to shed light on why DETU is an indispensable component for modern rubber formulations.

Understanding DETU's Role in Vulcanization

Vulcanization is the critical process that transforms raw rubber into a durable, elastic material by forming cross-links between polymer chains. Accelerators like DETU significantly speed up this process, allowing for lower vulcanization temperatures and shorter curing times. What sets DETU apart is its high activity, particularly in chloroprene rubber (CR). It promotes rapid vulcanization across a wide temperature range – low, medium, and high – making it incredibly versatile.

Applications and Performance Benefits

Our customers frequently purchase DETU for its exceptional performance in several key rubber types:

  • Chloroprene Rubber (CR): DETU is considered one of the most active thiourea accelerators for CR. It yields vulcanized rubber with superior tensile strength, hardness, and excellent compression permanent deformation resistance. When you buy DETU for CR, you are investing in enhanced material integrity.
  • EPDM Rubber: DETU acts as a valuable vulcanization activator for EPDM rubber systems, boosting the efficiency of sulfur vulcanization. For manufacturers looking to optimize EPDM processing, sourcing DETU from a reliable supplier is a strategic move.
  • Butyl Rubber: It also functions effectively as an accelerator for butyl rubber, contributing to the overall performance and curing characteristics of this specialized elastomer.

Furthermore, DETU finds its place in high-speed continuous vulcanization (CV) processes, especially for extruded products like wires and cables. Its ease of dispersion and the ability to achieve rapid vulcanization without excessive scorching (under specific formulation conditions) make it a preferred choice for such demanding applications. We are proud to be a manufacturer that supplies DETU that meets these industrial requirements.

Antioxidant Properties for Extended Product Life

Beyond its primary role as an accelerator, N,N'-Diethylthiourea also offers beneficial antioxidant effects for various rubbers, including natural rubber (NR), chloroprene rubber (CR), nitrile rubber (NBR), and styrene-butadiene rubber (SBR). This dual functionality can contribute to the longevity and durability of the final rubber products, reducing degradation from oxidative stress.
