Characteristics: Soluble in water, ethylene glycol and other solvents, weak water absorption at room temperature, stable at room temperature.

This product is an environmentally friendly flame retardant, suitable for permanent flame retardant modification of polyester, the resulting flame retardant polyester can be spinnable properties comparable to conventional PET, and can be spun through any spinning system. It has excellent thermal stability, does not decompose in the spinning process, and has no odor at the spinning site, which can improve the antistatic performance of polyester products, and is suitable for various fields where conventional PET can be applied. The addition amount of PTA and EG is 2.5-4.5%, the phosphorus content of the flame retardant polyester slice is 0.35-0.60%, and the flame retardant limit oxygen index of the spun fabric is 30-36%.
