2-carboxyethyl phenylphosphonic acid
CEPPA
CAS: 14657-64-8
Molecular Formula: C9H11O4P
Molecular Formula：214.16
Application: This product is a reactive halogen-free flame retardant suitable for the permanent flame retardant modification of PET and PBT of spinning grade. This product is a pre - polymer of flame retardant CEPPA and ethylene glycol, it controls the phosphorus content according to customer requirements. This product has a good color, which is beneficial to improve the polymerization degree of flame retardant PET, and can also be used as a polymerization monomer for halogen-free flame retardant modification of polyurethane.
