Antioxidant 1010
Antioxidant 1010 is a highly efficient, long-acting primary hindered phenolic antioxidant. It appears as a white powder and is characterized by low volatility, extraction resistance, and resistance to blooming.
It is primarily used for the long-term thermo-oxidative aging protection of polymer materials—often in combination with Antioxidant 168—and finds wide application in polyolefins, engineering plastics, elastomers, hot-melt adhesives, and other fields.
Detail
Antioxidant 1010 (Irganox® 1010)
一、 Basic Information
Chemical Name: Pentaerythritol tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]
CAS No.: 6683-19-8
Type: High-molecular-weight, tetra-functional hindered phenolic primary antioxidant; the most widely used general-purpose, long-term antioxidant globally.
二、Physicochemical Properties
Appearance: White, free-flowing crystalline powder/granules
Molecular Weight: 1177.65
Melting Point: 110–125°C
Volatile Content: ≤0.5%
Ash Content: ≤0.1%
Solubility: Soluble in acetone, toluene, and ethyl acetate; insoluble in water.
三、 Mechanism of Action and Key Advantages
✅ Scavenges oxidative free radicals, providing protection against thermo-oxidative aging during the product's long-term service life.
✅ High molecular weight; features low volatility, low migration, and resistance to water extraction; resistant to blooming/exudation.
✅ Colorless, non-staining, and low-yellowing; ideal for light-colored and white products.
✅ Low toxicity; suitable for use in food-contact packaging materials.
✅ Rarely used alone; typically compounded with secondary antioxidant 168 to achieve a synergistic effect (1+1 > 2).
Classic Blends: B215 (1010:168 = 1:2) – focuses on preventing processing yellowing; B225 (1010:168 = 1:1) – balances processing stability with long-term aging protection.
💡 Quick Comparison Tip: 1010 (tetra-functional) offers superior long-term performance, making it suitable for thick-walled products and long-term aging applications; 1076 (mono-functional) offers better compatibility, making it more suitable for films and hot-melt adhesives.
四、Applicable Materials
PP (Polypropylene), PE (Polyethylene), EVA, POE elastomers, ABS, HIPS, PS, POM. Polymer materials such as POM, TPE/TPR, hot-melt adhesives, cable compounds, and synthetic rubber.
五、 Recommended Dosage
Standard polyolefins: 0.1–0.25%
Products requiring long service life or operating under harsh conditions: 0.25–0.4%
六、 Packaging, Storage, and Transport
25 kg paper-plastic composite bags or fiber drums; store in a cool, dry, and sealed environment, protected from moisture; not classified as a hazardous chemical.
