Antioxidant 1076
Antioxidant 1076 is a highly efficient hindered phenolic antioxidant. This antioxidant is widely used in fields such as polyolefins, polyamides, polyvinyl chloride, ABS resins, and synthetic rubber, effectively preventing thermal and oxidative aging of materials during processing and use. When used in combination with auxiliary antioxidants like antioxidant 168 and DLTDP, its antioxidant effect can be significantly enhanced.
Antioxidant 1010
Antioxidant 1010 is a high-molecular-weight hindered phenolic antioxidant with high thermal stability and strong resistance to migration. It is mainly used for protecting against thermal oxidation of polypropylene, polyethylene, polyformaldehyde, ABS resins and synthetic rubber. Antioxidant 1010 has extremely low toxicity (LD50 for rats by oral administration is > 5g/kg). The general addition amount is 0.1% to 0.5%, and it is suitable for food packaging materials. Storage requires moisture-proof and heat insulation.
Antioxidant 626
Antioxidant 626 is a type of phosphite-based auxiliary antioxidant. It is generally regarded as an upgraded product of antioxidant 168. Its key features include resistance to yellowing and high transparency. It is a low-volatile organic synthetic antioxidant and polymerization inhibitor, and is widely used in the synthesis and processing of various plastics such as polypropylene, polyethylene, ABS, polycarbonate fibers, and polyester resins.
Antioxidant 225
Antioxidant 225 is a compound formed by blending phenolic antioxidant 1010 and phosphite ester antioxidant 168 in a ratio of 1:1. It exhibits excellent thermal and oxidative stability, low volatility, and good compatibility with various resins.
Antioxidant 215
Antioxidant 215 is a compound formed by blending phenolic antioxidant 1010 and phosphite ester antioxidant 168 in a ratio of 1:2. It exhibits excellent thermal and oxidative stability, low volatility, and good compatibility with various resins.
Antioxidant 168
Antioxidant 168 is a type of phosphite-based auxiliary antioxidant. It is a white crystalline powder with a melting point of 180-186℃. It is soluble in organic solvents such as benzene and toluene, but insoluble in water and alcohols. It has excellent anti-extraction and water stability properties, with low toxicity (LD50 for rats > 6000mg/kg). It is stable at room temperature but needs to be protected from high temperatures and strong oxidants.When combined with phenolic antioxidants, antioxidant 168 can produce a synergistic effect, enhancing the thermal and light stability of polymer products. It is mainly used in materials such as polyethylene, polypropylene, and polyester.
