Packing: 25kg cardboard drum or plastic bag lined woven bag

Features: Soluble in water, glycol and other solvents, weak water adsorption in
normal temperature, stable in room temperature

Uses: 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 0.35-0.60%, and the LOI of flame retarding products is 30~36%.
