Introduction to S-TMQ (CAS 26780-96-1)

S-TMQ, also known as a high-performance quinoline antioxidant, is widely used in the rubber industry for its superior thermal and oxidative aging resistance. This article provides a comprehensive overview of its chemical properties, applications, and safety considerations.

Chemical Properties

S-TMQ is a high-performance quinoline antioxidant with a higher effective body content compared to common TMQ. It contains a significant amount of dimer and trimer, which contribute to its excellent thermal and oxidative aging resistance。

Performance

Thermal and Oxidative Aging Resistance: S-TMQ exhibits superior resistance to heat and oxidative aging, making it ideal for applications requiring long-term stability。

Low Volatility and Pollution: S-TMQ has low volatility and minimal pollution, making it environmentally friendly and suitable for high-performance rubber products。

Improved Adhesion: Compared to common TMQ, S-TMQ has a very low content of non-effective bodies, which minimizes the impact on the reducibility of insoluble sulfur and enhances the adhesion between rubber and steel wire。

Applications

Tires: S-TMQ is widely used in tire manufacturing, particularly in tire belts and body ply compounds, to improve cord performance and adhesion。

Rubber Products: It is also used in various rubber products such as rubber tubes, belts, and hoses to enhance their durability and resistance to environmental factors。

Packaging and Transportation

Packaging: S-TMQ is typically packaged in paper/plastic bags with a net weight of 20 kg per package。

Transportation Conditions: It should be transported in clean, covered vehicles, avoiding direct sunlight, rain, and long-term compression, and kept away from heat sources。

Safety and Handling

S-TMQ is classified as a hazardous substance with the following hazard statements:

H302: Harmful if swallowed。

H315: Causes skin irritation。

H319: Causes serious eye irritation。

Precautionary Statements:

P261: Avoid breathing dust/fume/gas/mist/vapors/spray。

P280: Wear protective gloves/protective clothing/eye protection/face protection。

P305 + P351 + P338: If in eyes: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing。

P333 + P313: If skin irritation or rash occurs: Get medical advice/attention。

Conclusion

S-TMQ is a versatile and high-performance chemical compound with a wide range of applications in the rubber industry. Its improved properties, such as reduced volatility and enhanced adhesion, make it particularly suitable for products with higher environmental and performance standards. Proper handling and safety measures are crucial to ensure its safe and effective use
