DOPO, as a phosphene cyclic phosphate ester, belongs to the organophosphorus heterocyclic compounds and shows good performance advantages. It has high thermal stability and maintains a stable flame retardant effect even in high-temperature environments, providing reliable fire protection for products in the fields of polyester fibers, polyurethane foams, thermosetting resins and adhesives. At the same time, its oxidation resistance can effectively extend the service life of products and resist the erosion of various oxidizing factors. Its excellent water resistance allows DOPO to perform well in different use environments, whether it is in humid climate or water contact scenarios, without affecting its flame retardant properties.
DOPO is both a reactive and additive flame retardant, providing users with more choices and flexibility.
DOPO is widely used in a number of important fields such as polyester fibers, polyurethane foams, thermosetting resins and adhesives. In epoxy resins, it shows excellent performance as a reactive flame retardant.
First of all, DOPO is halogen-free and environmentally friendly, and is fully compliant with the European Union's ROHS directive. This means that products using DOPO can be sold and used worldwide without any hindrance and without having to worry about the restrictions imposed by environmental regulations. DOPO is the best choice for environmentally conscious and sustainable companies.
Secondly, DOPO provides excellent flame retardancy in a small amount. This not only reduces production costs, but also improves product performance. In polyester fibers, DOPO can effectively stop the spread of flame. In polyurethane foams and thermosetting resins, it also provides reliable flame protection.
In addition, DOPO has good dispersibility and can be evenly distributed in the material to ensure consistent flame retardant effect. Whether in the production process or in use, DOPO functions stably without uneven flame retardancy.
As a coloring preventive agent, DOPO also provides additional protection for products. It prevents discoloration of the product during use and maintains the beauty and quality of the product
The coloring preventive agent DOPO is also a good coloring preventive agent.
Flame retardant DOPO has become the flame retardant of choice in many industries due to its advantages of halogen-free and environmentally friendly, low dosage, good flame retardancy, good dispersion and coloring prevention.
