purpose
Phosphonite cyclic phosphate is an organophosphorus heterocyclic compound. With high thermal stability, antioxidation and excellent water resistance, it is a reactive and additive flame retardant. It is mainly used for polyester fiber, polyurethane foam, thermosetting tree ester and adhesive. As the flame retardant has phosphorus - carbon bond, the flame retardancy is better than that of the common phosphate. 1, PET is a common polyester fiber, is widely used in engineering plastics and synthetic fiber raw materials, but due to the flammability of polyester material made by application to limit, flame retardant treatment can improve the flame resistance of polyester, DDP is a new type of flame retardant, as grafting combination, modified polyester hydrolysis resistance after, can promote the droplet rapidly in combustion, flame retardant, has excellent flame retardant properties, limited oxygen index of T30-32, low toxicity, irritation of the skin, can be used in automobile, ship, senior hotel interior decoration, the defense industry and special labor protection. 2, the adhesive polyester adhesive is added to DDP to form resistance polyester adhesive. It has good stability and heat resistance, and it can also play a good adhesive role when using refractory as solvent.
