For permanent flame retardant PET, CEPPA can be added directly or after pre-esterfication with EG during the PET synthesize procedures. During the condensation polymerization procedure, the reaction time and pressure should be adjusted to get the appreciated viscosity and melting point of PET. The CEPPA should be added according to the required flame retardant properties. Consult our technical service of determining the polycondensation conditions. For polyester paint. CEPPA can be used after esterfication with EG. The CEPPA should be added according to the required flame retardant properties.
