When selecting antioxidants, attention should be paid to the cooperation between antioxidants, as well as the cooperation between antioxidants and other heat and light stabilizers. The specific content is as follows: (1) Sum up effect. The combination of multiple antioxidants can enhance their respective characteristics and effects, thereby increasing the overall effect. For example, when hindered phenols with different degrees of evaporation or steric hindrance are combined, their antioxidant effects can be enhanced over a wide temperature range. If only one type of antioxidant is used in the formula, it will inevitably involve a large amount and cause intense oxidation reactions at high concentrations, which is not allowed. But when using several low concentration antioxidants together, it not only achieves the desired intention, but also prevents intense oxidation and promotes its additive effect. (2) Synergy effect. ① When two are different

Antioxidant DNP is a light gray powder that is a type of chemical substance that undergoes a series of processing to produce hydrogen resistant products. Below is a brief introduction to several different types of anti hydrogen agent products. Anti hydrogen agent DNP. Light gray powder, easily soluble in aniline and nitrobenzene, insoluble in water. Suitable for polyethylene and polypropylene. Impact resistant polystyrene and ABS resin not only have antioxidant properties, but also have good thermal stability and suppress the influence of copper and lemon metals. Antihydrogen agent DLTP. White crystalline powder, melting point around 40 ℃, low toxicity, insoluble in water, soluble in benzene, carbon tetrachloride, and acetone. Used as an auxiliary antioxidant for polyethylene, polypropylene, ABS, and polyurethane resins, it can change the heat resistance and oxygen resistance of products. Anti hydrogen agent 1076. White or slightly yellow crystalline powder, non-toxic, insoluble in wa
