This product belongs to flame retardant of reaction series, it is used in production of copolyester chip of flame resistance. It is researched, developed by our chemicals plant. It is a new type of halogen-free phosphorous copolymerizing flame retardant. Its series of permanent flame retardant products not only have non-toxic, non-smoking and non-corrosion advantages but also have excellent flame retardant property, good quality and advanced technique in the word. The flame retardant polyester chip added flame retardant CPPA is steady under heat and very easy to spin as same as ordinary polyester. According to the test reports of the National Quality Testing and Inspection Center for Fireproof Construction Materials, the Limited Oxygen Index(LOI) of the flame retardant polyester fibre and fabrics which are made from flame retardant CPPA is 32-33%. These permanent flame retardant products can be widely used in decorating, garments, military goods, household goods and upholstery inside the plane, ship and car etc.
