Study on Synthesis and Properties of Dull Flame-Retardant Polyester

The phosphorus-containing flame-retardant polyesters from CEPPA and DDP in continuous polyester unit were produced.The production process of phosphorus-containing flame-retardant polyester and it's product properties were introduced.The results showed that the production process was steady and product quality was excellent.As compared with regular dull PET,the synthesized phosphorus-containing flame-retardant polyester had lower crystallization capacity,and better thermal stability.The synthesized phosphorus-containing flame-retardant polyester had excellent flame-retardant property.
