Specification:

Application: 
    CEPPA is a reactive type phosphorus serieseco-friendly flame retardant, which is suitable for the permanent flame retardant modification of polyester.
    CEPPA also can improve the antistatic performance of polyester products. It is widely used in spinning and fiber flame retardancy. Flame retardant polyester products have so excellent heat stability that it won’t decompose in spinning process. Besides, There is no smell at spinning area.
    The process of producing flame retardant PET chip: First, the pre-esterification of CEPPA and ethylene glycol to get esterified liquid. Then, copolymerization of esterified liquid and PTA to produce FR PET chips
    CEPPA additive amount during the copolymerization of PTA and EG is 2.5~4.5%; The phosphorus content of FRPET is 0.35-0.60%. After the spinning, flammability limit oxygen index
Packing:
25kg cardboard drum or plastic bag lined woven bag.
