BASF Antioxidants: The “Guardian” of the rubber industry

In the vast field of rubber industry, BASF antioxidants are like a conscientious “guardian” who is unknown but indispensable. It not only gives rubber products a longer life, but also improves its performance, making our lives more convenient and safe. Imagine what a world would look like without BASF antioxidants? Car tires may age and crack in a few weeks, conveyor belts may break frequently, and even the rubber gloves we use in daily life may become fragile. All this may sound exaggerated, but it is the existence of BASF antioxidants that make it possible.

This article will deeply explore the important role of BASF antioxidants in the rubber industry, and demonstrate how it can improve the life and performance of rubber products through detailed data, rich cases and domestic and foreign literature. At the same time, we will also lead readers into this seemingly professional but interesting field in easy-to-understand language combined with funny and humorous expressions. Whether you are a practitioner in the rubber industry or an ordinary reader interested in materials science, this article will open a new door for you.

Next, we will start from the basic principles of BASF antioxidants and gradually analyze their specific application in the rubber industry, revealing how it has become one of the key factors in extending product life. So, let’s get started!

The secret of rubber aging: Why do you need antioxidants?

Rubber is a natural or synthetic polymer material, and is widely used in various fields due to its unique elasticity and wear resistance. However, rubber is not an “immortal” material – it gradually loses its original properties over time, a phenomenon known as “aging”. The aging of rubber is like a person getting older, and is an inevitable process, but it can be delayed through scientific methods. And BASF antioxidants are an important tool to solve this problem.

What is rubber aging?

Rubber aging refers to the phenomenon that during the use of rubber materials, due to external environmental factors (such as oxygen, ultraviolet rays, heat, moisture, etc.), its molecular structure changes, resulting in a degradation in performance. Common aging manifestations include:

  • Decreased physical properties: increased hardness, decreased elasticity, and weakened tensile strength.
  • Appearance changes: cracks, fading or discoloration on the surface.
  • Reduced chemical stability: It is easy to react with other substances or even decompose.

These changes not only affect the appearance of the rubber product, but more importantly, they will weaken their functionality and thus shorten their service life.

Oxygen – the “number one killer” of rubber aging

Oxygen is the main “culprit” among many factors that cause rubber aging. When the rubber is exposed to air, oxygen will oxidize with double bonds or other active groups in the rubber molecule to form peroxides and other free radicals. These free radicals further trigger chain reactions, destroying the molecular structure of the rubber, and eventually leading to a comprehensive decline in rubber properties.

For example, in high temperature environments, rubber molecules are more likely to bind to oxygen, forming more free radicals, and accelerating the aging process. This is one of the reasons why car tires crack after driving for a long time.

BASF Antioxidants: “Shield” against aging

To resist the corrosion of oxygen on rubber, scientists invented antioxidants. As a world-leading chemical company, BASF has developed a series of antioxidants products that it has become an indispensable part of the rubber industry. The main function of antioxidants is to capture and neutralize free radicals, thereby preventing the oxidation reaction from continuing. In other words, antioxidants are like a solid “shield” that provides strong protection for rubber.

The working mechanism of antioxidants

Antioxidants delay rubber aging through the following two main mechanisms:

  1. Free Radical Capture: Antioxidants can quickly capture free radicals in rubber molecules and convert them into stable compounds, thereby interrupting the chain propagation of the oxidation reaction.
  2. Metal ion passivation: Some antioxidants can also inhibit the catalytic effect of metal ions on the oxidation reaction and further reduce the generation of free radicals.

For example, BASF’s Irganox series of antioxidants are highly efficient antioxidant additives designed based on the above principles, which can provide long-lasting protection during rubber processing and use.

The types and characteristics of BASF antioxidants

In the rubber industry, BASF antioxidants are known for their diversity and efficiency, and can meet the needs of different application scenarios. According to their chemical properties and mechanism of action, BASF antioxidants can be roughly divided into the following categories:
