Product Overview
Antioxidant 1010 is a high-performance, hindered phenolic primary antioxidant widely used to protect polymers and other organic materials against thermal oxidation during processing and long-term service.
As a chain-breaking antioxidant, Antioxidant 1010 helps neutralize free radicals generated during thermal and oxidative degradation. It helps maintain the mechanical properties, color stability, and long-term durability of polymer materials exposed to heat, oxygen, and demanding processing conditions.
Key Features and Benefits of Antioxidant 1010
Antioxidant 1010 provides several important benefits for polymer processing and product protection.
1.Excellent primary antioxidant performance: Helps interrupt oxidative degradation by scavenging free radicals.
Long-term thermal stability: Helps preserve polymer properties during processing, storage, and end-use exposure to heat.
2.Low volatility: Helps reduce additive loss under suitable processing and service conditions.
Good resistance to extraction and migration: Supports longer-lasting antioxidant performance in compatible formulations.
3.Color stability: Helps minimize oxidation-related discoloration and preserve the appearance of finished products.
Broad polymer compatibility: Suitable for a range of polyolefins, engineering plastics, elastomers, and adhesive formulations.
4.Synergistic stabilization: Can be combined with secondary antioxidants, such as phosphites or thioesters, to improve overall processing and long-term stability when the formulation is properly designed.
These properties make Antioxidant 1010 a versatile choice for manufacturers seeking to improve polymer durability and reduce oxidative degradation.

Applications of Antioxidant 1010
WSD Chemical's Antioxidant 1010 is suitable for evaluation in a wide range of industrial polymer and chemical formulations.
1. Polyethylene (PE) and Polypropylene (PP)
Antioxidant 1010 is widely used in polyethylene and polypropylene to help protect materials during melt processing and long-term use. Typical applications include plastic films, injection-molded parts, containers, fibers, woven bags, pipes, and other polyolefin products.
2. Engineering Plastics
Antioxidant 1010 can be incorporated into compatible engineering thermoplastics, including polyamide (PA), polycarbonate (PC), polyoxymethylene (POM), polyester, and ABS formulations, depending on processing temperatures and formulation requirements. It helps reduce thermal oxidation and supports the retention of physical and mechanical properties.
3. Rubber and Elastomers
In suitable synthetic rubber and elastomer formulations, Antioxidant 1010 helps reduce oxidative aging and supports the durability of finished products. Its use depends on the elastomer type, compounding system, and required performance.
4. Adhesives, Sealants, and Hot-Melt Systems
Antioxidant 1010 is used in compatible adhesives, sealants, and hot-melt formulations to help reduce oxidation during manufacturing and service. It can contribute to improved thermal stability and color retention.
5. Wire and Cable Materials
Antioxidant 1010 may be used in compatible wire and cable compounds, including selected polyolefin-based insulation and sheathing materials, to help protect against thermal oxidation during processing and service.
6. Synthetic Fibers and Other Polymer Products
Antioxidant 1010 can also be considered for synthetic fibers, thermoplastic elastomers, wood-plastic composites, and other polymer products that require improved resistance to oxidative degradation.
Recommended Dosage and Formulation Guidance
The appropriate dosage of Antioxidant 1010 depends on the polymer type, processing temperature, residence time, oxidation sensitivity, and desired service life. A preliminary dosage range of 0.05%–0.5% by weight is commonly referenced for selected polymer applications, but the optimum concentration must be established for each formulation.
For demanding processing conditions, Antioxidant 1010 may be combined with a secondary antioxidant, such as a phosphite antioxidant, to improve melt-processing stability. In outdoor applications, a suitable UV absorber or light stabilizer may also be required because antioxidant protection alone does not provide comprehensive protection against photodegradation.
Manufacturers should evaluate dispersion, compatibility, processing stability, color requirements, and the interaction between additives through laboratory trials and application-specific testing.

Frequently Asked Questions(FAQ)
What is Antioxidant 1010?
Antioxidant 1010 is a hindered phenolic primary antioxidant used to protect polymers and other compatible organic materials against thermal oxidation. Its CAS number is 6683-19-8, and its molecular formula is C73H108O12.
What is Antioxidant 1010 used for?
Antioxidant 1010 is commonly used in PE, PP, engineering plastics, rubber, elastomers, adhesives, and other polymer formulations. It helps reduce oxidative degradation during processing and long-term service.
How does Antioxidant 1010 work?
Antioxidant 1010 acts as a primary antioxidant by scavenging free radicals involved in oxidation chain reactions. This helps slow the degradation of polymer chains and supports the retention of mechanical properties and color stability.
What is the difference between Antioxidant 1010 and Antioxidant 168?
Antioxidant 1010 is a primary hindered phenolic antioxidant that scavenges free radicals. Antioxidant 168 is a secondary phosphite antioxidant that helps decompose hydroperoxides and protect polymers during processing. The two are often used together to provide complementary stabilization, subject to formulation requirements.
What is the recommended dosage of Antioxidant 1010?
A preliminary range of 0.05%–0.5% by weight is commonly referenced for selected polymer systems. The actual dosage should be optimized through formulation trials and performance testing.
Can Antioxidant 1010 be used with UV absorbers?
Yes. Antioxidant 1010 can be combined with suitable UV absorbers or light stabilizers when additional protection against outdoor exposure is required. The selection and dosage of each additive should be determined according to the polymer, application environment, and compatibility requirements.
