As a key ingredient in modern rubber formulations, Rubber Antioxidant TMQ (RD), identified by its CAS No: 26780-96-1, plays a pivotal role in extending the service life and improving the performance of rubber products across numerous industries. Known chemically as Polymerized 2,2,4-trimethyl-1,2-dihydroquinoline, TMQ is a highly effective, general-purpose antioxidant widely favored by rubber manufacturers.

Rubber materials, especially those exposed to harsh environments, are susceptible to degradation caused by heat, oxygen, ozone, fatigue stress, and weathering. This degradation process, often referred to as aging, leads to a loss of mechanical properties, cracking, and eventual failure of the rubber article. The incorporation of a potent antioxidant like TMQ is therefore essential to counteract these detrimental effects and preserve the integrity and functionality of the rubber over time.

TMQ (RD) functions by scavenging free radicals generated during the oxidation process, thereby interrupting the chain reaction that leads to polymer degradation. Its polymerized structure contributes to its excellent non-blooming characteristics, meaning it tends to stay within the rubber matrix rather than migrating to the surface, which can cause undesirable cosmetic issues and reduced efficacy. This attribute makes it particularly suitable for applications where surface appearance and consistent protection are critical.

The physical form of Rubber Antioxidant TMQ (RD) is typically a dark brown granule, making it easy to handle and incorporate into rubber compounding processes. Its specifications usually include a softening point in the range of 80-100 °C, a low heating loss (typically 0.5% max), and minimal ash content (around 0.4% max). These properties ensure consistent performance and compatibility within various rubber formulations, including natural rubber and a wide range of synthetic rubbers.

Applications for Rubber Antioxidant TMQ (RD) are extensive. It is a cornerstone ingredient in the tire industry, used in critical components like tire treads, sidewalls, and innerliners to withstand the severe stresses of road use and environmental exposure. Beyond tires, TMQ is vital for the production of industrial rubber goods such as conveyor belts, transmission belts, hoses (for automotive, industrial, and hydraulic applications), cables, footwear components, and various molded and extruded rubber parts that require superior aging resistance.

The effectiveness of TMQ in providing long-term protection makes it an indispensable additive for products designed for durability and reliability. Its ability to perform under high temperatures and dynamic stress conditions is particularly valued in demanding applications.

For companies seeking to ensure the longevity and performance of their rubber products, sourcing high-quality Rubber Antioxidant TMQ (RD) is a critical step. As a reliable supplier and manufacturer of chemical raw materials, NINGBO INNO PHARMCHEM CO.,LTD. understands the importance of consistent quality and supply chain reliability.
