For professionals in the rubber manufacturing sector, understanding the specific functions and benefits of chemical additives is crucial for optimizing product performance and longevity. N-Isopropyl-N'-phenyl-1,4-phenylenediamine, identified by its CAS number 101-72-4, commonly known as IPPD, is a highly effective antioxidant and antiozonant that plays a vital role in protecting rubber products from degradation. This guide is designed to equip buyers with the knowledge needed to source and utilize IPPD effectively.

IPPD is a chemical compound characterized by its ability to shield rubber polymers from the damaging effects of ozone and continuous flexing. Its molecular structure, C15H18N2, allows it to act as a free radical scavenger and react with ozone, thus preventing the formation of cracks and preserving the material's elasticity and strength. This makes it an indispensable additive for rubber goods that face environmental exposure and mechanical stress.

The principal applications of N-Isopropyl-N'-phenyl-1,4-phenylenediamine are found in the tire industry, where it provides crucial protection against ozone attack and heat aging for components like treads and sidewalls. It is particularly effective in Nitrile Butadiene Rubber (NBR) and is also used in various other rubber products such as conveyor belts, hoses, and seals. When considering to buy IPPD, buyers often look for suppliers who can guarantee high purity and consistent quality to ensure optimal performance in their formulations.

Procurement specialists aiming to purchase IPPD (CAS 101-72-4) will benefit from understanding market dynamics and supplier capabilities. Manufacturers in China are a significant source for this chemical, offering competitive pricing, especially for bulk orders. Key considerations when sourcing include product specifications (e.g., assay purity, appearance), packaging (e.g., 25kg bags), lead times, and the availability of technical documentation like COAs and MSDS. Establishing a relationship with a reliable manufacturer ensures a stable supply of this critical raw material.

The physical properties of IPPD, such as its dark gray to black flake appearance and a melting point around 75°C, are important for handling and processing. While IPPD is highly effective, it does have a tendency to cause discoloration, making it best suited for applications where color is not a primary concern. For R&D scientists, understanding the optimal incorporation levels of IPPD is essential for maximizing its protective benefits without compromising other material properties.

In essence, N-Isopropyl-N'-phenyl-1,4-phenylenediamine (CAS 101-72-4) is a premium antioxidant essential for enhancing the performance and extending the service life of rubber products. By focusing on quality sourcing and understanding its unique properties, rubber manufacturers can leverage IPPD to create more durable and reliable end products.
