Bag making machine commonly used antioxidant performance and use, let us understand it
1. Quaternary [β- (3, 5-di-tert-butyl-4 hydroxyphenyl) propionic acid] pentaerythritol ester is also known as antioxidant 1010. White liquid powder, melting point 120 ~ 125℃, low toxicity. It is a good antioxidant. Polypropylene resin is used more, is a kind of high thermal stability, very suitable for use under high temperature conditions, bag function to extend the service life of products, in addition, can also be used in most other resins. The general dosage is not more than 0.5%.
2. Beta – (3, 5-di-tert-butyl-4-hydroxyphenyl) octadecyl propionate is 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 an antioxidant of 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%. Can be used as food packaging materials molding additives.
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. Suitable for polypropylene, polyethylene, polyvinyl chloride, ABS and polyamide resin antioxidant, bag making machine and can be used in contact with copper wire, cable. Generally, the dosage does not exceed 0.5%.
4.2, 6-di-tert-butyl-4-methylphenol, also known as antioxidant 246. White or light yellow crystalline powder or flake, melting point at about 70℃, boiling point at 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 molding materials (polyvinyl chloride, polypropylene, polyethylene, polyester, polystyrene and ABS) resin. The general dosage is 0.01% ~ 0.05%.
