The product is widely used in PP, PE, POE, ABS, PS, PVC, engineering plastics, synthetic fibers, elastomers, adhesives, wax, synthetic rubber, and petroleum products. It is suitable to be added in the aggregation, production, or use. It is often used with auxiliary antioxidant such as 168, and the antioxidant performance is better. Storage
Stabilization of γ-radiation vulcanized EPDM rubber
Antioxidants protect rubbers by interrupting the oxidative processes that occur during processing, irradiation, storage and service. Aromatic amines and phenol derivatives are the most commonly used antioxidants,and no universal antioxidant is known for all types of rubber and all modes of aging. The two major classification of antioxidants
Antioxidant 1010. Antioxidant 1010 is a polyphenol antioxidant that is compatible with most polymers. It has good effect on preventing discoloration caused by light and heat. It is widely used in PE, PP, PS, polyamide, polyformaldehyde, ABS resin, PVC, synthetic rubber and other polymer materials. Antioxidant 168.
Elastomers Elastomer Additives Antioxidants
Antioxidant 168 is used in low volatile organic synthesis of antioxygen. Widely used in polypropylene, Polyethylene, ABS, polycarbonate fiber and polyester resin and other plastics synthesis and processing. It has excellent synergistic effect with main antioxidant 1010 and 1076

Antioxidant UV stabilizer additives guide. 1. Polymer degradation and stabilization. Autoxidation may be initiated by heat, high energy radiation such as ultraviolet light, mechanical stress, or through reaction with other impurities. Antioxidant delay the formation of free radical species and hydroperoxides in polymers both during storage and
- What are the primary antioxidants for polymers?
- The majority of primary antioxidants for polymers are sterically hindered phenols. Part of primary antioxidants, are aromatic amines, mainly used in carbon-black filled rubbers and some polyurethane applications. Irganox ® 5057 is such an aromatic amine for polyol and rubber stabilization.
- Which antioxidants are used in polyolefins?
- Products Irgafos ® 168, Irganox ® 245 and Irgastab ® FS 301 are commonly used. Antioxidants Irganox ® 1010, Irganox ® 1076 and Irgafos ® 168 are the industry standard used mainly in Polyolefins, such as polyethylene and polypropylene. More than 50 years ago BASF invented Irganox ® 1010.
- Is 1010 more effective than 1076?
- Both are hindered phenolic antioxidants, but the effective functional group of 1010 is four times more than that of antioxidant 1076, which means that it is more effective. The main considerations for usage are compatibility with the resin at a later stage and processing conditions. Properties of antioxidant 1010: white crystalline powder.
- What is 1010 1076 and 168?
- According to the mechanism of action, 1010,1076 belongs to capture free radicals and 168 belongs to decompose hydroperoxides. The first two are the main antioxidants, 168 is an auxiliary antioxidant, the main antioxidant is to focus on the product’s long-term anti-aging, auxiliary antioxidants are generally stabilized in the process!
- What is Irganox 1076?
- Irganox 1076 is a high-performance, sterically hindered phenolic primary antioxidant, widely recognized for its exceptional efficiency in various applications. Used extensively in the polymer industry, this versatile additive exhibits remarkable compatibility and low volatility, making it an essential component in numerous manufacturing processes.
- What is hindered phenolic main antioxidant?
- A widely used hindered phenolic main antioxidant. It has good compatibility with the material, many with phosphite ester antioxidant compound with use. Apply to: All kinds of common plastics, engineering plastics, rubber and elastomer, coating and adhesive polymer materials, etc.
