For procurement managers and R&D scientists in the rubber and specialty chemical industries, sourcing high-quality intermediates is paramount. Dioctyldiphenylamine, identified by CAS number 101-67-7, is one such critical compound, primarily valued for its role in enhancing the performance of various rubber products. If you are in the market to purchase this chemical, understanding its properties, applications, and how to effectively source it from reliable manufacturers in China can significantly streamline your procurement process.

Understanding Dioctyldiphenylamine (CAS 101-67-7)

Dioctyldiphenylamine, also known by its chemical name 4-Octyl-N-(4-octylphenyl)aniline, is typically supplied as a white powder with a purity of 99% or higher. Its molecular structure lends itself to applications where improved durability, flexibility, and resistance are crucial. Key physical properties include a melting point of 96-97°C, indicating it is a solid at standard room temperatures, and a high boiling point. These characteristics make it suitable for incorporation into various high-temperature processing applications within the rubber industry.

Key Applications in the Rubber Industry

The primary utility of Dioctyldiphenylamine lies in its ability to act as a vital additive in a wide array of rubber products. This includes its use in:

  • Specialty Cables: Enhancing the electrical insulation properties and overall longevity of cable sheathing.
  • Rubber Shoes: Improving the wear resistance, flexibility, and anti-aging characteristics of shoe soles and components.
  • Rubber Flooring: Contributing to the resilience, durability, and anti-slip properties of industrial and commercial rubber flooring.
  • Sponge and Foam Products: Modifying the cell structure and enhancing the physical properties of rubber sponges.
  • Synchronous Belts: Improving the tensile strength, elasticity, and resistance to degradation in high-performance belts.
  • Sealing Rubber Rollers: Providing the necessary resilience and chemical resistance for industrial rollers used in various manufacturing processes.

When formulating these products, the consistent quality and purity of the Dioctyldiphenylamine supplied are critical for achieving the desired end-product performance. Sourcing from a reputable manufacturer that guarantees these specifications is key.

Sourcing from China: What Buyers Need to Know

China has emerged as a significant hub for the production and export of specialty chemicals, including intermediates like Dioctyldiphenylamine. For B2B buyers looking to purchase this chemical, several factors should be considered:

  • Supplier Reliability: It is essential to partner with established manufacturers that have a proven track record of quality and consistency. Look for suppliers who can provide detailed technical data sheets (TDS), certificates of analysis (CoA), and information on their quality management systems.
  • Purity and Specifications: Confirm that the product meets your required purity levels (e.g., 99% min) and other critical specifications outlined in the technical data.
  • Pricing and Value: While price is always a consideration, it should be balanced with quality and reliability. Competitive pricing from Chinese manufacturers often stems from efficient production processes and economies of scale, but always ensure value for money. Requesting free samples is a standard practice to verify product quality before committing to a large order.
  • Supply Chain Stability: Ensure the manufacturer can guarantee a stable and timely supply chain, especially for bulk purchases. Understanding their production capacity and logistics capabilities is important.
  • Regulatory Compliance: While this intermediate is primarily used in industrial applications, it's good practice to ensure the supplier is aware of and adheres to relevant chemical regulations.

By focusing on these aspects, procurement professionals can confidently buy Dioctyldiphenylamine (CAS 101-67-7) from trusted Chinese suppliers. Engaging directly with manufacturers allows for better negotiation on price and ensures direct communication regarding product specifications and delivery schedules. For those seeking to purchase this intermediate, exploring options from established chemical suppliers in China will be a crucial step toward optimizing their material sourcing strategy.
