2- carboxyethyl phenylphosphonic acid
CEPPA
CAS: 14657-64-8
Molecular Formula: C9H11O4P
Molecular Formula：214.16
Application: This product belongs to the environmental protection flame retardant, suitable for the permanent flame retardant modification of polyester. The spinnability of the flame retardant polyester obtained is similar to that of conventional PET and PBT, and can be processed by any spinning system. It has excellent thermal stability, no decomposition in the spinning process and no odor in the spinning site. It can improve the antistatic performance of polyester products. CEPPA is suitable for the application of conventional PET in all fields.
