I. What is Antioxidant 1010?

AAntioxidant 1010, also known as pentaerythritol tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid] ester (trade name, e.g., Irganox 1010), is a multi-component hindered phenolic antioxidant, prepared by esterification of pentaerythritol with four hindered phenolic units. It is one of the most widely used hindered phenolic antioxidants in plastics industry. The chemical formula is often written:

C73H108O12 (pentaerythritol tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid], CAS No.: 6683-19-8, molecular weight: approx. 1177.63)

At room temperature it is a white crystalline powder, melting at about 110-125 °C. It is readily soluble in such organic solvents as chloroform, benzene, acetone, but insoluble in water. Antioxidant 1010 has four active groups of hindered phenol (3,5-di-tert-butyl-4-hydroxyphenyl), which can trap free radicals (ROO·, RO·, HO· etc.) in the polymer oxidation chain reaction and break the oxidation chain reaction, thus inhibiting the thermal oxidative degradation of polymer materials in processing and use.

Antioxidant 1010 contains a pentaerythritol core with four symmetrically disposed hindered phenolic arms. Its high molecular weight and multifunctional structure gives low volatility, resistance to extraction, excellent thermal stability and good compatibility with most polymers. It can extend the life of materials and avoid color change caused by light and heat. It is a typical product of the antioxidant which scavenges free radicals mainly.

Antioxidant 1010 is chemically stable, odorless, non-toxic and does not taint the products. It can act synergistically with some phosphite-based auxiliary antioxidants (antioxidant 168, for example) and greatly improve the long-term thermal stability. Store it in a sealed, moisture-proof, and light-protected environment.

Industrial grade antioxidant 1010 has 98% or higher content and is used in industrial applications such as plastics, rubber, fibers and coatings. Industrial grade products are concentrated on the following indicators:

1. Melting point

Melting point is a standard factory inspection index. It reflects the purity and quality of the product. It must be controlled in the indicated range (about 110-125℃).

2. Volatile matter (loss on heating)

Volatile matter is low boiling point impurities and moisture, which affect the processing stability and performance of the product, and should be kept at a very low level.

3.Ash

Ash content reflects the total amount of inorganic impurities, which affects product purity and product quality, and must be controlled within a reasonable range.

4.Light transmission

The light transmittance (425nm/500nm) is a measure of the product’s color and impurity content and affects the quality of transparent products, so it is necessary to maintain a high light transmittance.

5. Solubility

The product should be well soluble in organic solvents like chloroform, benzene etc. without any obvious matter insoluble so that the formulation is uniformly dispersed.

6. Chromaticity (APHA)

The color intensity affects the initial coloration of products, so low color intensity should be maintained for stable product color.
