Antioxidant 1010, known by its chemical name Pentaerythritol tetrakis (3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate), is a high molecular weight, hindered phenolic antioxidant. This compound plays a very effective role in preventing oxidative degradation in polymers and polymeric materials.

Physical and chemical properties of Antioxidant 1010

Antioxidant 1010 is a white, odorless powder with high thermal stability. It is insoluble in water, but soluble in organic solvents such as benzene, toluene, chloroform and to some extent in alcohols.

•        High stability to heat and light

•        Excellent performance at high temperatures

•        Non-volatile and low toxicity

•        Compatible with a wide range of polymers

•        Suitable for combination formulations with phosphite antioxidants or light stabilizers

Function of Antioxidant 1010 in polymers

The main function of this antioxidant is to inhibit free radicals that cause degradation of the polymer structure during thermal processes or long-term storage. Antioxidant 1010, with its bulky structure, inhibits the oxidation reaction and increases the shelf life, maintains mechanical properties and prevents yellowing or brittleness of products.

Applications of Antioxidant 1010

•        Polyethylene (PE)

•        Polypropylene (PP)

•        Polystyrene and ABS

•        Polyesters and polyurethanes

•        Elastomers and synthetic rubbers

•        Industrial adhesives and coatings

•        Natural and synthetic oils (lubricants)

•        Paints, resins and process fluids

This material is usually used in combination with Antioxidant 168 or other phosphite antioxidants for optimal performance in high temperature environments.

Benefits of Antioxidant 1010

1. Extends the life of polymer products
2. Prevents deterioration of physical and visual properties of materials
3. Suitable for a wide range of production processes (extrusion, molding, etc.)

Antioxidant 1010 is one of the most widely used and effective additives in the plastic and chemical industries and plays a key role in the stability of heat-sensitive formulations.
