As a B2B professional in the chemical industry, understanding the specific applications and benefits of key chemical intermediates is vital for successful product development and procurement. N,N-Diphenyl-p-phenylenediamine (DPPD), identified by CAS number 74-31-7, is a critical component widely used as an antioxidant and stabilizer across various industries, most notably in rubber and plastics. As a leading manufacturer and supplier based in China, we are dedicated to providing high-purity DPPD to meet the stringent demands of global markets.

DPPD's chemical structure, C18H16N2, grants it excellent properties for protecting polymers from degradation caused by oxidation, heat, and ozone. In the rubber industry, it is indispensable for enhancing the durability and service life of products made from natural rubber, styrene-butadiene rubber (SBR), nitrile-butadiene rubber (NBR), and butyl rubber, among others. Its ability to prevent flex cracking and heat aging makes it a preferred choice for applications where longevity and performance under stress are crucial. For procurement managers, understanding the direct benefits – such as improved flex life, enhanced resistance to hot-oxygen and ozone, and good color stability in non-staining applications – is key to making informed purchasing decisions.

When considering where to buy DPPD, partnering with a well-established Chinese manufacturer like ourselves offers significant advantages. We ensure that our N,N-Diphenyl-p-phenylenediamine consistently meets a purity standard of 99% or higher, often complying with USP, BP, and EP standards where applicable. This commitment to quality, coupled with our competitive pricing, makes us an ideal supplier for businesses looking to optimize their supply chain and product quality. We also support online purchases and can provide detailed technical specifications, including melting point (typically 143-145°C) and low water content, to assist your R&D and production teams.

Beyond rubber, DPPD serves as a stabilizer for engineering plastics such as polyethylene, polypropylene, and polyamides, improving their resistance to climate-induced degradation. This broad applicability makes DPPD a versatile chemical intermediate. If your operations require a reliable source of high-quality DPPD, we invite you to contact us for a quote.
