Application 



As one kind of environment-friendly fire retardant, it can be used permanent flame retarding modification of polyester, and the spinnability of flame retarding polyester is similar to PET, thus it can be used in all kinds of spinning system, with features as excellent thermal stability, no decompound during spinning and no smell. 







It can be used in all the application fields of PET to improve antistatic capacity of polyester. The dosage for copolymerization of PTA and EG is 2.5~4.5%, the phosphorus assay of flame retarding polyester sheet is 0.***0.*0%, and the LOI of flame retarding products is *0~*6%.
