BASF Antioxidants: The "anti-oxidant expert" in the industry
In today's rapidly changing era, whether in daily life or industrial production, antioxidant has become an important topic that cannot be ignored. Just like our daily life supplementation of vitamin C to delay aging, in the industrial field, the antioxidant properties of materials are directly related to the service life and quality stability of the product. BASF, as a leading enterprise in the global chemical industry, has launched a variety of high-efficiency antioxidant products with its deep R&D strength and rich industry experience, providing comprehensive antioxidant solutions for plastics, rubbers, coatings and other fields.
What are antioxidants?
Antioxidants are chemicals that can inhibit or slow down oxidation reactions. They can prevent the occurrence of free radical chain reactions at the molecular level, thereby extending the service life of the material. Imagine if you cut a fresh apple and soon you will find that its surface begins to turn yellow, which is the result of oxidation. And if you apply a layer of lemon juice to the cut apple, it can effectively slow down this discoloration. By the same token, antioxidants are like the "lemon juice" of industrial materials, providing them with a protective barrier to prevent problems such as aging and spoilage caused by oxidation.
The importance of antioxidants is particularly prominent in industrial applications. For example, plastic products may age due to factors such as sunlight exposure and high temperature environment during long-term use, resulting in performance degradation and even cracks. By adding appropriate antioxidants, the durability and stability of these materials can be significantly improved, allowing them to maintain good performance under various harsh conditions.
Core advantages of BASF antioxidants
As one of the world's leading chemical companies, BASF's antioxidant product line is known for its outstanding performance and wide application range. Here are some key features:
- Efficient antioxidant properties: BASF antioxidants can accurately capture free radicals at the molecular level, thereby effectively inhibiting the occurrence of oxidation reactions.

Next, we will explore the specific application scenarios and technical parameters of BASF antioxidants to help you better understand thisFeatures and advantages of a range of products.
Main application scenarios of BASF antioxidants
BASF antioxidants have become an indispensable key ingredient in many industries due to their outstanding performance and diversity. From plastics to rubbers, from coatings to lubricants, BASF antioxidants cover almost all areas where antioxidant protection is needed. The following are several typical application scenarios and corresponding antioxidant selection strategies:
1. Plastics Industry
Background and Requirements
Plastic is one of the common materials in modern society, but because its molecular structure contains a large amount of carbon and hydrogen bonds that are easily oxidized, it is susceptible to ultraviolet rays, oxygen and high temperatures, resulting in reduced performance and even failure. In order to extend the service life of plastic products and ensure their stable performance in different environments, the effect of antioxidants is particularly important.
Main products and features
| Product Model | Chemical Name | Features | Application Fields |
|---|---|---|---|
| Irganox 1076 | Monophenolic antioxidants | Good thermal stability, low volatility, suitable for high melting point polymers | Polyolefins, polyesters, etc. |
| Irganox 1010 | Stealed phenolic antioxidants | Strong antioxidant capacity and high cost performance | Injection molding, extrusion, blow molding process |
| Irgafos 168 | Phosphate antioxidants | Auxiliary antioxidant, which can work synergistically with the main antioxidant | Engineering Plastics, PP, PE, etc. |
Practical Case Analysis
Take car interior as an example, plastic parts are prone to aging due to the high temperature inside the car and long-term exposure to sunlight. By adding the composite formula of Irganox 1076 and Irgafos 168, it can not only effectively slow down the oxidation process, but also improve the processing properties and surface gloss of the material.
2. Rubber industry
Background and Requirements
Rubber products are widely used in tires, seals, conveyor belts and other fields, but their natural flexibility also makes them more susceptible to oxidative damage. Especially under dynamic loading conditions, the risk of rubber molecular chain breakage is higher, so stronger antioxidant protection is required.
Main products and features
| Product Model | Chemical Name | Features | Application Fields |
|---|---|---|---|
| Naugard 445 | Amine antioxidants | Highly effective antioxidant, and has UV protection function | Dynamic load rubber products |
| Naugard A-47 | Trumped amine antioxidants | Especially effective for vulcanized rubber | Tyres, sealing strips |
| Irganox MD1024 | Solid antioxidants | Easy to disperse, suitable for powder rubber mixing | Shoemaking and sports equipment |
Practical Case Analysis
In tire manufacturing, Naugard 445 is often used in combination with other additives to form a comprehensive protection system. Experimental data show that tires treated with this formula have improved their performance in durability tests by about 20%, greatly extending the service life of the product.
3. Coatings and inks
Background and Requirements
Coatings and inks usually require good adhesion, wear resistance and color stability, and these properties are susceptible to oxidation. Especially for paints used outdoors, they must be able to resist damage caused by ultraviolet radiation and atmospheric pollution.
Main products and features
| Product Model | Chemical Name | Features | Application Fields |
|---|---|---|---|
| Tinuvin 765 | Light Stabilizer | Providing long-term light protection | Exterior wall coatings, anticorrosion coatings |
| Chimassorb 944 | UV absorber | Block UV rays to prevent coating degradation | Auto paint, wood paint |
| Irganox 245 | Liquid Antioxidants | Good liquidity, easy to mix | Inks, solvent-based coatings |
Practical Case Analysis
A well-known paint brand has introduced a combination of Tinuvin 765 and Chimassorb 944 in its high-end exterior wall paint, successfully extending the product's color retention time from the original 3 years to more than 8 years. This not only improves customer satisfaction, but also brings significant market competitiveness to the company.
4. Lubricating oil and hydraulic oil
Background and Requirements
Lumeric oil and hydraulic oil play a crucial role in the operation of mechanical equipment, but long-term high-temperature and high-pressure environments will cause the oil to oxidize and form precipitates, which will affect the performance of the equipment. Therefore, choosing the right antioxidant is crucial to maintaining the cleanliness and lubricating effect of the oil.
Main products and features
| Product Model | Chemical Name | Features | Application Fields |
|---|---|---|---|
| Irganox L57 | Synthetic Ester Antioxidants | Hydrolysis resistant, suitable for extreme pressure conditions | Industrial gear oil, hydraulic oil |
| Irgalube TP-D | Phosphate antioxidants | Provides additional wear protection | Engine oil, transmission fluid |
| Irganox L135 | Comprehensive Antioxidant | Balance oxidation and corrosion resistance | Aviation hydraulic oil, special oil products |
Practical Case Analysis
A large construction machinery manufacturer used Irganox L57 as an additive in its hydraulic system. The results show that after a year of continuous operation, the viscosity change rate of hydraulic oil is only 5%, which is far lower than the 10% specified in the industry standard. This not only reduces maintenance costs, but also improves the reliability of the equipment.
