For professionals in the chemical industry, a deep understanding of a compound's properties and applications is fundamental to its effective utilization. 1,3-Dibutyl-2-thiourea (CAS 109-46-6) is a prime example of a versatile fine chemical with a unique set of characteristics that make it invaluable in various industrial processes, particularly in rubber manufacturing.

Chemically, 1,3-dibutyl-2-thiourea, with the molecular formula C9H20N2S and a molecular weight of 188.33, presents itself as a white to light yellow crystalline powder. Its initial melting point typically ranges from 60.0°C to 65.0°C, indicating its solid state at ambient temperatures. Key specifications often include a low loss on drying (≤0.30%) and minimal ash content (≤0.30%), signifying high purity and consistency, which are critical for precise chemical formulations.

Its primary application is as a fast vulcanization accelerator for chloroprene rubber (CR). Its performance is comparable to other well-known accelerators like ETU and DETU. However, its advantages extend to being a secondary accelerator for natural rubber (NR), styrene-butadiene rubber (SBR), and EPDM. This makes it a flexible component for compounders looking to optimize cure rates and physical properties of elastomers.

Beyond acceleration, 1,3-dibutyl-2-thiourea serves as a potent antioxidant and antiozonant. This dual functionality protects rubber products from degradation caused by oxidation and ozone exposure, thereby enhancing their durability and service life. This is particularly beneficial for rubber components in demanding environments.

When seeking to purchase this chemical, buyers often search for '1,3-dibutyl-2-thiourea CAS 109-46-6 supplier' or 'buy rubber accelerator.' Connecting with manufacturers in China, such as those specializing in fine chemicals, can provide access to high-quality material at competitive prices. Ensure you request detailed specifications and SDS/TDS from potential suppliers to confirm suitability for your specific application.
