Product Information

Name: 2-Carboxyethyl(phenyl)phosphinic acid 
Synonyms: 3-Hydroxyphenylphosphinyl-propanoic acid; CEPPA
Molecular Formula:  C9H11O4P

CAS No:  [14657-64-8]
Melting point:  ≥158 °C
Decomposition Temperature: 210°C (5%)
Water solubility:  readily soluble
Physical state: white crystals 
Content: 99.50 %(min)
Application: 2-Carboxyethyl(phenyl)phosphinic acid is a bifunctional copolymerisable phosphorous flame retardant monomer, which can be polycondesated with ethylene glycol and terephthalate to form flame retardant PET, and renders the alternated PET and the resulting plastics and fibers good fire-resistance property. The spinning property of the PET is fairly good as the CEPPA was used.

Usable method: Added after pre-esterfication with EG during the PET synthesize procedures.  Addition of approx. 4.5% CEPPA  during polycondensation process. The P-content of the resulting flame retardant polyester is approx. 0.6%. Consult our technical service of determining the polycondensation conditions
Packing: 25kgs in barrel
