Usage:
1.Use for the manufacture of organic synthesis, pesticides and pharmaceutical intermediates;It is an important intermediate, is widely used in the preparation of organic phosphorus flame retardants, organophosphorus pesticides , antioxidants, plasticizers, stabilizers, insecticides, paints and lubricants catalyst and high pressure forming agent,Reactive flame retardant. Also can be used in Clothing production.

2.This product belongs to the environmentally friendly flame retardant, apply to the permanent flame retardant modification of polyester, obtained flame retardant polyester spinning performance with conventional PET, can be through any spinning system for spinning processing.It has excellent thermal stability, does not occur in the process of spinning decomposition, spinning the scene without peculiar smell, can improve the antistatic performance of polyester products, application of various fields for conventional PET can.When with PTA, EG copolymerization of adding amount of 2.5 ~ 4.5%, and the phosphorus content of flame retardant polyester chip is 0.35-0.60%, after spinning fabric flame retardant limit oxygen index of 30 ~ 36%.
