Antioxidants are a class of chemicals that, when present in only a small amount in a polymer system, can delay or inhibit the oxidation process of the polymer, thus Prevents the aging of polymers and extends their service life, also known as “anti-aging agents”.
Let’s learn about 9 commonly used antioxidants:
Antioxidant 1010:White flowing powder, The melting point is 120-125℃, the toxicity is low, and it is a good antioxidant. It is widely used in polypropylene resin. It is an additive with high thermal stability and is very suitable for use under high temperature conditions. It can extend the service life of the product. In addition, it can also be used in most other resins.
Antioxidant 1076: White or slightly yellow crystalline powder, melting point is 50~55℃, non-toxic, insoluble in water, soluble in benzene, acetone, ethane and esters solvents. It can be used as an antioxidant for polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyamide, ABS and acrylic resins. It has the characteristics of good antioxidant properties, low volatility, and resistance to washing. It can be used as an additive for forming food packaging materials.
Antioxidant 164: White or light yellow crystalline powder or flakes. The melting point is 70℃, the boiling point is 260℃, and it is non-toxic. It is used in a variety of resins and has a wide range of uses. It is more suitable for use in resins used in food packaging molding materials (polypropylene, polyethylene, polyvinyl chloride, ABS, polyester and polystyrene).
Antioxidant CA: White crystalline sealant, melting point 180-188°C, toxic droplets, soluble in acetone, ethanol, toluene and ethyl acetate. Suitable for antioxidant additives in polypropylene, polyethylene, polyvinyl chloride, ABS and polyamide resins, and can be used for wires and cables in contact with others.
Antioxidant DNP:Light gray powder, melting point is about 230℃, easily soluble in aniline and nitrobenzene, insoluble in water. Suitable for polyethylene and polypropylene. Impact-resistant polystyrene and ABS resin, in addition to their antioxidant properties, also have good thermal stability and inhibit the influence of metals such as copper.
Antioxidant DLTP: White crystalline powder, melting point is around 40°C, low toxicity, insoluble in water, soluble in benzene, carbon tetrachloride, and acetone. Auxiliary antioxidant for polyethylene, polypropylene, ABS and PVC resin, which can change the heat resistance and antioxidant properties of products.
Antioxidant TNP:Light yellow viscous body, freezing point lower than -5 and boiling point higher than 105℃, odorless and non-toxic, insoluble in water, soluble in acetone, ethanol, benzene and carbon tetrachloride, suitable for polyvinyl chloride, polyethylene, polypropylene, impact-resistant polystyrene, ABS, polyester and other resins, with high antioxidant properties at high temperatures.
Antioxidant TPP:Light yellow transparent liquid, freezing point 19-24℃, boiling point 220℃, soluble in alcohol, benzene and acetone, suitable for polyvinyl chloride and polyphenylene Auxiliary antioxidant for ethylene, polypropylene and ABS resins.
Antioxidant MB:Light yellow powder, melting point greater than 285°C, soluble in ethanol, acetone, ethyl acetate, insoluble in water and benzene. An antioxidant suitable for polyethylene, polyamide and polypropylene resins; this product does not pollute or color, and can be used in white or brightly colored products.
