PRODUCT DESCRIPTION:

This product is a flame retardant liquid made by esterfication of 2-carboxyethyl phenyl phosphinic acid

(CEPPA ) and ethylene glycol (EG) under specific conditions,

TYPICAL APPLICATIONS:

CEPPA esterifying liquid of EG could be added during the precondensation procedure to prepare PET. The

flame retardant liquid can improve the polymerization property of CEPPA and efficiently reduce the content of

free CEPPA. It can also improve the flame retardant property of the alternated PET, and make it a really block

copolymer.
