Performance and application of antioxidant commonly used in bag making machine

The properties and uses of antioxidants commonly used in Bag Making Machine are as follows.
1. Tetra [β - (3,5-di-tert-butyl-4-hydroxyphenyl) propionic acid] pentaerythritol ester, also known as antioxidant 1010. It is a white powder with a melting point of 120-125 ℃ and low toxicity. It is a good antioxidant. Polypropylene resin is widely used, is a kind of high thermal stability, very suitable for the use of high temperature conditions, Bag making machine can extend the service life of products, in addition, it can also be used in most other resins. The general dosage is not more than 0.5%.
2. Octadecyl β - (3,5-di-tert-butyl-4-hydroxyphenyl) propionate, also known as antioxidant 1076. White or yellowish crystalline powder, melting point 50-55 ℃, non-toxic, insoluble in water, soluble in benzene, acetone, ethane and esters and other solvents. It can be used as antioxidant for polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyamide, ABS and acrylic resin. It has the characteristics of good oxygen resistance, low volatility and washing resistance. The general dosage is not more than 0.5%. It can be used as additive for food packaging materials.
3.1,1,3-tri (2-methyl-4-hydroxy-5-tert-butylphenyl) butane is also known as antioxidant ca. White crystalline powder, melting point 180-188 ℃, low toxicity, soluble in acetone, ethanol, toluene and ethyl acetate. It is suitable for antioxidant of polypropylene, polyethylene, polyvinyl chloride, ABS and polyamide resin, bag making machine and wire and cable in contact with copper. The general dosage is not more than 0.5%.
4.2,6-di-tert-butyl-4-methylphenol, also known as antioxidant 246. White or light yellow crystalline powder or sheet, melting point about 70 ℃, boiling point about 260 ℃, non-toxic. Used in a variety of resins, insoluble in water, can better inhibit oxidation, thermal decomposition and the influence of copper, so it is widely used. Bag making machine is more suitable for food packaging materials (PVC, PP, PE, pet, PS and ABS) resin. The general dosage is 0.01% ～ 0.05%.
