1.strong antioxidant performance: can effectively delay or inhibit the oxidation process in the chemical reaction, so as to protect the substance from oxidative damage.
2.thermal stability: can maintain its oxidation resistance at high temperatures, often used in applications under high temperature conditions.
3.low volatility: it is not easy to evaporate or decompose from the material, and can maintain its antioxidant effect for a long time.
4.it is good compatibility with the material, and is used in combination with phosphite ester coantioxidants; In outdoor products can be used with benzotriazole ultraviolet absorbers and blocked amine light stabilizers for a variety of general plastics, engineering plastics, rubber and elastomers, coatings and adhesives and other polymer materials.
It is often used as an antioxidant in stainless steel products, electronic products, auto parts, etc., which can prevent the oxidative aging of plastic materials under high temperature and long exposure; Suitable for rubber products, such as tires, seals and rubber pipes, can extend their service life, and improve heat resistance and weather resistance; Often used in various paints, it can effectively protect the coating surface to prevent oxidation and aging.
Addition amount: 0.05-1%, the specific addition amount is determined according to customer application test.
