Diphenylguanidine (DPG), a fundamental chemical compound in the rubber industry, serves as a crucial secondary accelerator. Understanding its properties, applications, and procurement best practices is essential for anyone involved in rubber compounding and manufacturing. This guide aims to provide a clear overview and assist in making informed purchasing decisions.

DPG, chemically known as 1,3-Diphenylguanidine and identified by CAS number 102-06-7, is a white to light yellow powder or granular substance. It is sparingly soluble in water but readily soluble in organic solvents like ethanol and acetone. Its primary function in rubber vulcanization is to activate primary accelerators, such as thiazoles and sulfenamides, leading to faster cure rates and improved physical properties of the final rubber products. For professionals looking to buy DPG, recognizing its catalytic and activating role is key.

The applications of DPG are diverse, spanning across various rubber products. It is widely used in the manufacturing of tires, particularly radial tires, where it contributes to enhanced tensile strength and abrasion resistance. Beyond tires, DPG finds utility in mechanical rubber goods, footwear components, adhesives, and latex products. Its ability to provide good scorch safety, meaning it allows for a longer processing window before vulcanization begins, makes it a favored choice for many manufacturers.

When considering purchasing DPG, understanding its specifications is vital. Key parameters include melting point, loss on drying, ash content, and residue on sieves. Sourcing DPG from reputable manufacturers, especially from China, can offer significant cost advantages without compromising on quality. A good DPG supplier will ensure that the product meets industry standards and is consistently available. NINGBO INNO PHARMCHEM CO.,LTD. is a trusted DPG manufacturer and supplier, dedicated to providing high-quality chemicals.

For those involved in rubber compounding, DPG can also act as a plasticizer in certain formulations, such as chloroprene rubber. Its effectiveness is often maximized when used in combination with other accelerators, allowing for tailored vulcanization systems. Whether you are looking to enhance cure rates, improve scorch safety, or boost the mechanical properties of your rubber products, DPG is a versatile and valuable additive.

In conclusion, Diphenylguanidine (DPG) CAS 102-06-7 is a cornerstone chemical for the rubber industry. Its properties as a secondary accelerator make it indispensable for a wide range of applications, from tires to footwear. For businesses seeking to purchase DPG, partnering with a reliable DPG supplier in China ensures quality, consistency, and competitive pricing.
