For professionals in the chemical and rubber industries, a thorough understanding of key raw materials is essential for successful product development and manufacturing. Diphenyl Guanidine (DPG), identified by CAS number 102-06-7, is a vital rubber accelerator that enhances the vulcanization process and improves the final properties of rubber products. This article provides a comprehensive overview of DPG, its characteristics, applications, and the strategic benefits of sourcing it from China.

Diphenyl Guanidine, with the molecular formula C13H13N3, is a white or grayish powder or granular substance. It is classified as a medium-speed accelerator, meaning it promotes the vulcanization process at a moderate rate, striking a balance between processing safety and cure efficiency. This characteristic makes it particularly suitable for a wide range of rubber types, including Natural Rubber (NR), Styrene-Butadiene Rubber (SBR), Nitrile Butadiene Rubber (NBR), and Chloroprene Rubber (CR), among others.

The primary application of DPG is in the manufacturing of tires, especially radial tires. Its ability to provide slack effective and high-speed vulcanization ensures that rubber compounds can be processed without premature hardening (scorch), while still achieving a fast cure rate. This leads to improved product quality, enhanced durability, and greater manufacturing efficiency. Apart from tires, DPG is also utilized in the production of various industrial rubber goods such as conveyor belts, footwear, and seals.

When sourcing DPG, manufacturers and formulators often look for key specifications such as purity (typically ≥97%), initial melting point (around 144°C), and low levels of heating loss and ash content. These parameters are crucial for ensuring consistent performance and predictable outcomes in rubber formulations. Buyers also frequently search for reliable suppliers who can provide competitive pricing and a stable supply chain.

China hosts a significant number of DPG manufacturers and suppliers who are well-equipped to meet global demand. Sourcing from these companies can offer distinct advantages. These include access to high-purity products, competitive price structures due to economies of scale, and efficient logistics for international distribution. Working with established suppliers ensures that you receive detailed product documentation, such as COA and TDS, and that the products comply with international quality standards.

In conclusion, Diphenyl Guanidine is an essential component in modern rubber manufacturing. Its unique properties as a vulcanization accelerator significantly contribute to the performance of tires and other rubber products. For businesses looking to secure a reliable supply of high-quality DPG, exploring the offerings from reputable Chinese manufacturers is a strategic move that can lead to improved product quality and cost efficiencies. Consider reaching out to key suppliers to obtain quotations and samples to meet your specific manufacturing needs.
